Suggestion about the best BeansWrapper

Jacopo Cappellato — 2012-05-14T16:19:36

Hi all,

recently Daniel Dekany helped me in this list to fix a deadlock condition happening under special conditions when OFBiz (http://ofbiz.apache.org) screens were rendering Freemarker templates; during that interesting thread Daniel also mentioned that the way about the way we use BeansWrapper in OFBiz; here is the relevant part of the conversation:

=====================================================
QUESTION (me): Currently in OFBiz we are using the default object wrapper:

BeansWrapper defaultOfbizWrapper = BeansWrapper.getDefaultInstance();

do you think we should use a different one?

ANSWER (Daniel): I'm not sure. There are two problems with the current one:

- If you look at what map keys FreeMarker sees (`<#list k as
 someMap?keys>${k} </#list>`), it mixes the actual Map keys with the
 methods of the Map class. This I already find annoying enough to
 stay away. But it's also dangerous, because if you are unlucky and
 have key like "get", then someMap.get and someMap[myDynamicKey]
 where myDynamicKey happens to be "get" will return the get method
 instead of the map item. You can think further what if you have
 a custom Map class and you add methods to it. Using
 someMap.get("theKey") is robust however, but too verbose.

- It doesn't wrap W3C DOM nodes automatically in a way so that the
 user can use FreeMarker's XML processing facility. It also doesn't
 wrap Jython or Rhino JavaScript objects nicely.

What I like to use is:

  BeansWrapper wrapper = new BeansWrapper();
  wrapper.setSimpleMapWrapper(true);

This will not expose the methods of Map-s, only the keys of it. If you
want to get a map item that has a non-string key, you don't have
someMap.get(key) anymore, but you can use someMap(key) instead. If
it's a custom Map class with custom methods that you want to call from
the template, then you are out of luck, however. And in your case
these changes wouldn't be backward-compatible.

As of supporting W3C DOM nodes, Jython and such, it's very easy to
create a custom ObjectWrapper that does that. Just look at
DefaultObjectWrapper.

As of DefaultObjectWrapper, it's burdened with backward-compatibly,
and so wraps collections on an technically awkward way, plus it
doesn't provide any hacks for the non-String key problem. I don't see
a point of using that.

Anyway, the situation with Map-s and the "advertised" object wrappers
is something that had to be hammered out for ages. Sadly nobody has
found the time/incentive for it so far...
=====================================================

Based on Daniel's suggestions I have tried to replace:

BeansWrapper defaultOfbizWrapper = BeansWrapper.getDefaultInstance();

with

BeansWrapper defaultOfbizWrapper = new BeansWrapper();
defaultOfbizWrapper.setSimpleMapWrapper(true);

Unfortunately this change causes some errors in several screens because of ftl code snippets like:

1) ${currency.get("description",locale)}
2) <#assign roleType = quoteRole.getRelatedOne("RoleType")>

In the above examples "currency" and "quoteRole" are instances of GenericValue; this is a custom OFBiz class that implements Map<String, Object>

In order to fix these issues I have removed the method call:
defaultOfbizWrapper.setSimpleMapWrapper(true);

In this way the screens seem to work fine.

However I am not sure if there are side effects or if there are real advantages in using:
new BeansWrapper();

rather than:

BeansWrapper.getDefaultInstance();

Could you please provide some hints?

Thank you

Jacopo

how to pass value from code to page template

S Ahmed — 2012-05-10T04:20:23

I have a page template that I use for all my pages like:

<#macro page title="soem title">
<html>
  <title>${title}</title>
</html>
<body>
..
<#nested>

</body>

</#macro>

Then in my page I am doing:

<#import "/page.ftl" as p>

<< at >p.page title="some title">

...


What if I wanted to get the title from my java code, and pass it down, is
that possible?

I'm using spring, and my view gets the ModelAndView values, can I set it
from the server side and pass it as a parameter for title?

Scheduled downtime of freemarker.org

Stephan Müller — 2012-04-25T07:03:09

The server which hosts freemarker.org will be down for several hours due 
to maintenance work at the data center, approximately from

   Wed, 25 Apr 2012 20:15:00 GMT

to

   Thu, 26 Apr 2012 03:00:00 GMT


Hopefully the server will be back online a little bit sooner.



Stephan.

confused about html escaping

S Ahmed — 2012-04-23T14:14:25

My page is wrapped in a module that does has html escaping:

<#escape x as x?html>
..

<#nested>
..

</#escape>

Then my nested section is outputing the values of a collection like this:

<pre>
                    <#list someCollection as doc>
                        <div class="line">${doc.line}</div>
                    </#list>
</pre>

Now the value of line is like "< some text here>"

But on my page, it is showing up as blank.  Looking at the actual rendered
html it shows blank also.  When I set a breakpoint in my code, I can see
that the collection has the value "< some text here >" for the item in the
collection 'someCollection'.

I tried removing the <#escape x as x?html> also and nothing changed, still
don't see the row.

I just want to safely display this information like this in the html:  &lt;
some text here &gt;

loop a treemap

S Ahmed — 2012-04-22T20:34:06

How can I display both key and value paris inside of a treemap?

Do I still use the #list macro?

FreeMarker and PostScript?

John D. Ament — 2012-04-21T17:35:11

Hi All,

I'm considering using freemarker in an upcoming project.  One question I
had, does FreeMarker support post script? Are there any tutorials for
generating post script using freemarker?

John

Deadlock issue

Jacopo Cappellato — 2012-04-18T15:06:07

Hi all,

I know the question could be silly but we are struggling with a deadlock issue and I am wondering if any of you could give some hints to locate the problem.
We are using Freemarker (2.3.10) in a server with high traffic and we are experiencing a deadlock that makes the server very unstable.
Here are the details of the deadlock:

Thread 1:
a) ClassBasedModelFactory.get is called: this method acquires a lock on the "cache" variable
b) the method then calls BeansWrapper.introspectClass: this method attempts to acquire a lock on "classCache" variable

Thread 2:
x) BeansWrapper.introspectClass is called: this method acquires a lock on the "classCache" variable
y) the method then calls BeansWrapper.introspectClass that in turn calls ClassBasedModelFactory.clearCache: this method attempts to acquire a lock on "cache" variable

If the two threads are concurrent and perform the tasks in the following order:
a
x
b
y
we get the deadlock.

Now: we are sure this is the cause of the problem; what we do not know, and I am hoping on your help, is what could be cause that 2 threads perform the calls axby on the two objects ClassBasedModelFactory and BeansWrapper
I suspect it may be something wrong we are doing with Freemarker templates, include directives etc...

Thanks,

Jacopo

using includes inside a macro?

S Ahmed — 2012-04-10T17:35:30

Is it possible to have includes in a macro?

My macro has a varialbe isSignedIn which is defaulted to false.

I want to include 2 other templates, both are navigation html elements, 1
for logged in users and the other for not.

So depending on the isSignedIn flag, I want to display a specific include.

help in understand how to reference my objects inmy view

S Ahmed — 2012-04-09T20:10:12

I have a UserSession object that I add into my model like:


UserSession userSession = get....

ModelAndView mav = new ModelAndView("..");


mav.add("session", userSession);

return mav;

Now in my index.ftl page I want to do this:

if userSession.isLoggedIn
<p>....
</p>
end if

How do I do that using freemarker?

I tried this:

<#if session.isSignedIn>
</#if>

But I get an error saying that session.isSignedIn has to return true/false.
 Is does return true/false, so what is wrong?

thanks!

freemarker and spring

S Ahmed — 2012-04-09T19:25:26

When using freemarker and spring, I was looking at the source code of the
freemarker viewresolver etc. and I recall seeing a place where request
attribute level objects can merged into the ModelAndView that is sent to
the view.

Is this true?

So if I have:

request.setAttribute("someObject", someObject);

that I set using a filter for example, when my view is rendered does this
mean the someObject will be available in my freemarker view or is there is
a config setting I have to switch to allow for this to happen?

Freemarker DTD Validation Issue - Urgent

Ram Palagummi — 2012-04-04T14:50:47

Hi,

We use Freemarker on our site to generate dynamic sections of the pages. Recently, we have been noticing DTD validation errors and the issue seems to be with connecting to java.sun.com and it is intermittent. 

Is there anyway to turn off DTD validation (We understand its not a best practice) or any alternative to resolve this issue? This is Urgent.

Thanks

reqest a getExpression() method forfreemarker.core.InvalidReferenceException

eric east — 2012-04-03T17:59:46

For exception handling, I would like to capture the actual expression that 
failed.  It appears the only way to get the expression is to parse the Strings 
returned in the detailMessage and/or the ftlInstructionStack.

accessing JAXB generated properties of a bean (accessing static inner class)

Walker, Robert — 2012-03-30T03:55:30

Hi all, I was turned onto freemarker today and really impressed with it, and wanted to use it to generate spreadsheetML
(xml that  Excel will open as if it were a xlsx file)

I am having problems accessing properties buried a few layers deep.

Basically, I have a   OrganisationInfo class which contains an OrganisationInfo. NetworkList object,
And that networkList property contains a List of Network objects, from which I need to get
property values.

I am wondering if JAXB has generated something freemarker can't be used to access in it's template.

I want to try something like

cfg.setObjectWrapper(  new DefaultObjectWrapper() );
SimpleHash root = new SimpleHash();
// expose JAXB generated java object
root.put("organisationInfo", organisationInfo);

then my template has accessing syntax like

<h1> ${organisationInfo.networkList[0].tadigCode} </h1>

Is this possible with freemarker? Is there an example of this anywhere?
I get various errors Expected hash. organisationInfo.networkList[0] evaluated instead to freemarker.template.SimpleScalar.

Thanks all




I have JAXB generated classes like this

OrganisationInfo.java
=====================
< at >XmlRootElement(name = "OrganisationInfo")
public class OrganisationInfo
{
< at >XmlElement(name = "NetworkList", required = true)
protected OrganisationInfo.NetworkList networkList;

.
.
.

< at >XmlAccessorType(XmlAccessType.FIELD)
< at >XmlType(name = "", propOrder = {"network"})
public static class NetworkList
{
              < at >XmlElement(name = "Network", required = true)
        protected List<Network> network;
.
.
}
}


Network.java
============
< at >XmlRootElement(name = "Network")
public class Network
{
    < at >XmlElement(name = "TADIGCode", required = true)
    protected String tadigCode;

      .
      .

}

Difficulty with XPath and Namespaces usingEclipse with simple ANT build

Robert Johnson — 2012-03-26T15:19:48

Hello

Put simply, I cannot get Freemarker to process XPath queries or recognise XML namespaces - even using the examples out of the documentation. I am sure this must mean I'm doing something silly, but I cannot work out what.

Specifically; my XML document looks like this:-

<?xml version="1.0" encoding="UTF-8"?>
<book title="Test">
  <chapter title="Ch1">
    <para>p1.1</para>
    <para>p1.2</para>
    <para>p1.3</para>
  </chapter>
  <chapter title="Ch2">
    <para>p2.1</para>
    <para>p2.2</para>
  </chapter>
</book> 

and my template like this

<#assign book=document.book>
<h1>${book.< at >title}</h1>
<#list book.chapter as ch>
  <h2>${ch.< at >title}</h2>
  <#list ch.para as p>
    <p>${p}
  </#list>
</#list>  
<---- Next list --->
<#list document["book/chapter[title='Ch1']/para"] as p>
  <p>${p}
</#list> 
<--- do the original again -->
<#list book.chapter as ch>
  <h2>${ch.< at >title}</h2>
  <#list ch.para as p>
    <p>${p}
  </#list>
</#list>  
<---- Count -->
${document["count(//para)"]}  

and my output looks like

<h1> title="Test"</h1>
  <h2> title="Ch1"</h2>
    <p><para>p1.1</para>
    <p><para>p1.2</para>
    <p><para>p1.3</para>
  <h2> title="Ch2"</h2>
    <p><para>p2.1</para>
    <p><para>p2.2</para>
<---- Next list --->
<--- do the original again -->
  <h2> title="Ch1"</h2>
    <p><para>p1.1</para>
    <p><para>p1.2</para>
    <p><para>p1.3</para>
  <h2> title="Ch2"</h2>
    <p><para>p2.1</para>
    <p><para>p2.2</para>
<---- Count -->
  

As you can see, the XPath just doesn't return anything (nor any error) and yet all this is a direct copy out of the documentation on-line.

It gets worse if I try and use namespaces.

Change the basic XML to look as below

<?xml version="1.0" encoding="UTF-8"?>
<e:book xmlns:e="http://example.com/ebook" 
    title="Test">
  <e:chapter title="Ch1">
    <e:para>p1.1</e:para>
    <e:para>p1.2</e:para>
    <e:para>p1.3</e:para>
  </e:chapter>
  <e:chapter title="Ch2">
    <e:para>p2.1</e:para>
    <e:para>p2.2</e:para>
  </e:chapter>
</e:book>  


Use the template that follows:

<#ftl ns_prefixes={"e":"http://example.com/ebook"}>

<#recurse>

<#macro "e:book">
  I'm the book element handler. ${.node.< at >title}
</#macro>  

and get this output (which is correct)

  I'm the book element handler. Test

BUT, use this template

<#ftl ns_prefixes={"e":"http://example.com/ebook"}>
<#assign book=document["e:book"]>
<h1>${book.< at >title}</h1>
<#list book["e:chapter"] as ch>
  <h2>${ch.< at >title}</h2>
  <#list ch["e:para"] as p>
    <p>${p}
  </#list>
</#list>  
<---- Next list --->
<#list document["e:book/e:chapter[title='Ch1']/e:para"] as p>
  <p>${p}
</#list> 
<--- do the original again -->
<#list book["e:chapter"] as ch>
  <h2>${ch.< at >title}</h2>
  <#list ch["e:para"] as p>
    <p>${p}
  </#list>
</#list>  
<---- Count -->
${document["count(//e:para)"]}  

and you get a Java exception

[freemarker] Mar 26, 2012 4:15:35 PM freemarker.log.JDK14LoggerFactory$JDK14Logger error
[freemarker] SEVERE: Template processing error: "Namespace prefix e is not registered."
[freemarker] Namespace prefix e is not registered.
[freemarker] The problematic instruction:
[freemarker] ----------
[freemarker] ==> assignment: book=document["e:book"] [on line 2, column 1 in books.ftl]


even if the syntax were wrong in itself, the namespace has been registered. So it seem that ns_prefixes works if you use declaratives (recurse) but not if you use imperatives.

Can any kind person suggest what I am getting wrong??

Thanks in advance

Listing enumerations

Tim Pizey — 2012-03-09T17:31:24

Hi,

I have a method which returns an Enumeration, but when it is rendered
with #list or #foreach
an exception is thrown:

?size is unsupported for: freemarker.ext.beans.OverloadedMethodModel
The problematic instruction:
----------
==> list melati.database.displayTables as table [on line 67, column 50
in org/melati/admin/Top.fml]
----------

Java backtrace for programmers:
----------
freemarker.template.TemplateModelException: ?size is unsupported for:
freemarker.ext.beans.OverloadedMethodModel
at freemarker.ext.beans.OverloadedMethodModel.size(OverloadedMethodModel.java:149)
at freemarker.core.IteratorBlock$Context.runLoop(IteratorBlock.java:174)
at freemarker.core.Environment.visit(Environment.java:428)

The template is:

<select name="table" OnChange="submit();" title="Select table to edit">
<#assign lasttype = "">
<#assign selected = false>
<#list melati.database.displayTables as table>
  <#if !table.tableInfo.category.equals(lasttype)>
    <option value="">&nbsp;</option>
    <option value="">${table.tableInfo.category.name}</option>

      <#assign selected = true>
    </#if>
   </#if>
  </#if>> ${ml.rendered(table.displayName)}</option>

I am using BeanWrapper.

The documentation for #list
http://freemarker.sourceforge.net/docs/ref_directive_list.html
says, as far as I can understand, that an enumeration and and iterator
should be usable.

Sorry if this is a newbie error.

thanks in advance

I can access it from <data> index like ${doc.header.doc[2]} but I don't know
how to access it from < at >label value.

I try many ways but still got error
${header.data[< at >label='TradingStatus']}
${header.data.< at >label['TradingStatus']}
${header.data["< at >label='TradingStatus'"]}

Please help.....

FreeMarker 2.3.19 is out!

Download:
http://sourceforge.net/projects/freemarker/files/freemarker/2.3.19/freemarker-2.3.19.tar.gz/download

GAE-compatible binary:
http://sourceforge.net/projects/freemarker/files/freemarker/2.3.19/freemarker-gae-2.3.19.jar/download

Changes
-------

Don't miss the security related changes, they may affect your
application!

Changes on the FTL side:

* Attention: The output of ISO 8601 date/time formatting built-ins,
introduced in 2.3.17, was slightly changed. From now on, the time
zone offset, when it's displayed and it isn't Z, always includes the
minutes. For example, 15:30:15+02 becomes to 15:30:15+02:00 in the
template output. Both formats are valid according to ISO 8601 (so
anything that expects ISO 8601 date/times should continue working),
but only the last format complies with the XML Schema date/time
formats, hence this change.

* New built-in for escaping inside JSON string literals: json_string.

* Bugfix: Wrong # tags were printed as static text instead of causing
parsing error if there was no correct # tag earlier in the same
template. Since fixing this would not be 100% backward compatible,
the old behavior has remained, unless you set the
incompatible_enhancements setting
(Configuration.setIncompatibleEnhancements(String)) to "2.3.19" or
higher.

Changes on the Java side:

* Attention: This release contains two important security workarounds
that unavoidably make it obvious how some applications can be
exploited. FreeMarker can't solve these issues on all
configurations, so please read the details instead of just updating
FreeMarker! Also, these changes are not 100% backward compatible in
theory, however it's not probable that they will break anything. The
two changes are:

- The character with character code 0 (\u0000) is not allowed in
template paths anymore. When a path contains it, FreeMarker
behaves as if the template was not found.

This is to fix the security problem where a template path like
"secret.txt\u0000.ftl" is used to bypass extension filtering in an
application. FreeMarker itself doesn't care about the extension,
but some applications decide based on the extension if they will
delegate a path to FreeMarker. When they do with such a path, the
C/C++ implementation behind the storage mechanism may sees the
path as "secret.txt" as the 0 terminates the string in C/C++, and
thus load a non-FTL file as a template, returning the file
contents to the attacker.

Note that some HTTP servers, notably Tomcat and Apache will block
URL-s containing 0, but some others, like Jetty, doesn't.

- ClassTemplateLoader, when it's created with base path "/" (like
with new ClassTemplateLoader(someClass, "/")), will not allow
template paths that contain colon earlier than any /, and will act
like if the template was not found in such case.

This is to fix the security problem where a template path like
"file:/etc/secret" or "http://example.com/malware.ftl" is
interpreted as a full URL by a java.net.URLClassLoader in the
class-loader hierarchy. This is a quirk (or bug) of
java.net.URLClassLoader.

Beware, some frameworks use their own TemplateLoader
implementations, and if those are vulnerable, they will remain so
after updating FreeMarker too! Note that this exploit only works
if the class-loader hierarchy contains an URLClassLoader and the
class-loader is used to load templates without adding any prefix
before the template path (other than "/").

These security issues mostly affect applications where the user (the
visitor) can supply arbitrary template paths. This is not the case
with properly built MVC applications, as there only the Controller
can be addressed directly, and it's the Controller who specifies the
template paths. But MVC applications based on JSP Model-2 often
expose the MVC Views as URL-s ending with .ftl, thus allowing the
user to give arbitrary paths to FreeMarker. Such applications should
be secured with a security-constratint in web.xml as shown here:
http://freemarker.org/docs/pgui_misc_servlet.html#pgui_misc_servlet_model2
This should be done regardless of the current security fixes.

* Configuration has new methods: removeTemplateFromCache(...). This
will remove the given template for the given locale from the cache,
so it will be re-loaded regardless of the template update delay when
it's next time requested.

* BeansWrapper ignores setter methods from now when introspecting
classes. They weren't used anyway, so they unnecessarily caused
"java.beans.IntrospectionException: type mismatch between read and
write methods" errors.

* TemplateClassResolver.SAFER_RESOLVER now disallows creating
freemarker.template.utility.JythonRuntime and
freemarker.template.utility.Execute. This change affects the
behavior of the new built-in if FreeMarker was configured to use
SAFER_RESOLVER, which is not the default until 2.4 and is hence
improbable.

* Bug fixed: Calling varargs methods now indeed works. (Earlier it
only worked for overloaded methods.)

* Bug fixed [1837697] [2831150] [3039096] [3165425]: Jython support
now works with Jython 2.2 and 2.5.

* Bug fixed [3325103]: TemplateException-s and ParseException-s are
now serializable.

Input requited for a RFI

Rajnish Taneja — 2012-02-29T05:52:31

HI,

I am working on a RFI related to content adaptation and as part of that evaluating different templating engines. I am looking for a comparison matrix comparison Freemarker with other similar solutions. Kindly share the same if one available. Also any information on different parameters against which a templating engine should be evaluated will be helpful as well.

Since working on aggressive timelines, will appreciate an early response.

Thanks
Rajnish

Cannot load template in Linux using SpringFreeMarkerConfigurationFactory

Peter Kleczka — 2012-02-22T21:12:59

Hi

I have a web app on Tomcat 6 that loads FreeMarker templates via
org.springframework.ui.freemarker.FreeMarkerConfigurationFactory. The web
app is plain JSP (not Spring MVC). The app works fine in a Windows
environment, but will not work on Linux (Slackware 13.37 64 bit). When I
run it on Linux it gives me a file not found exception. I have tried
multiple variations on this configuration including putting my templates
directory in the classpath, using Spring prefixes like "file:" and
"classpath:" for the templateLoaderPath.  Nothing has worked.  Please let
me know if you have any ideas to fix. Thanks, Peter.

    <!-- Freemarker template config factory. Works on Windows -->
    <bean id="freemarkerTemplateConfigFactory"
class="org.springframework.ui.freemarker.FreeMarkerConfigurationFactory">
        <property name="templateLoaderPath" value="/WEB-INF/ftemplates/" />
    </bean>

    <bean id="templateService" class="com.mypkg.service.TemplateService">
       <property name="configurationFactory"
ref="freemarkerTemplateConfigFactory" />
    </bean>

Calling macro with tricky parameter name

Jerker Klang — 2012-02-22T15:21:31

Hello all,

I have a macro that I want to use for producing html5 page (fragments). 
It looks like this:

<#macro input id params...>
<#list params?keys as param>
     Key: ${param}<br />
     Value: ${params[param]}<br />
</#list>
</#macro>

Question: How do I call that macro with parameter named data-custom with 
the value freemarker?

The naive aproach would have been:

<< at >input id="something" data-custom="freemarker" />

Background:
In html5 they have the new convention that you can enter custom data 
attributes  on elements by using a data- prefix on all attributes. I 
suspect that my question is likely to reoccur in the future as html5 
becomes more common.

I've browsed through the FAQ and .vars in mentioned for accessing the 
variables but that isn't a problem me (since I'm iterating through params).

Is there a way to specify a tricky parameter name somehow?

Thanks in advance!

//Jerker
