Using Freemarker from Mule transformer

Alex Thieme — 2012-05-26T03:39:16

I am having problems using a templating engine like Freemarker or Velocity from within a Mule deployed app. I've had similar ClassNotFoundExceptions using both Freemarker and Velocity. I suspect there's some magic Mule or Maven dependency problem, but I'm not sure what. As an aside, I first tried using Velocity and had a ClassNotFoundException (org.apache.velocity.exception.VelocityException), too. And, I followed the steps outlined in David Dossot's Mule In Action example (http://code.google.com/p/muleinaction/source/browse/branches/mule-3/chapter05/velocity-transformer/?r=483).

Using Freemarker as the example, when I attempt to deploy my application to Mule, I get the following Exception.

Caused by: java.lang.ClassNotFoundException: freemarker.cache.TemplateLoader
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

Dynamic "to" address on smtp:outbound-endpoint based on inbound object

Alex Thieme — 2012-05-22T18:06:24

I've tried all manner of examples to make the properties on the smtp outbound-endpoint dynamic based on the incoming object (e.g. email address). No luck.

In my case, there's a Message object that is put on "queue.passwordChangeEmail". Message/Password/email contains the address I want used in the "to" field.

I've included a minimal set of configuration that does send an email. All that's missing is accessing the Message object to use the email as the "to" field.

Some things I've tried and issues I've encountered:

If I don't include the object-to-string-transformer, then the email is never sent. Depending on where I reference the transformer, I get no email.

I've tried creating a custom transformer that calls muleMessage.setOutboundProperty("to", email), then returns a string as the body of the email. Despite where I've referenced the custom transformer, it never gets called.

I've tried xpath expressions like to="#[string:#[xpath:/Message/Password/email/text()]]" and to="[string:[xpath:/Message/Passwo

Embedded webapp in Mule and SSL?

Håkan Dahl — 2012-05-16T10:58:36

Can SSL be used for a webapp embedded in Mule 3.2, like the
Bookstore-example webapps?

I tried to use the jetty-SSL transport instead of the non-SSL-jetty
transport used in the Bookstore example, but it seems like the jetty-SSL
transport doesn't support the "webapps" sub-element which is used in the
Bookstore-example:

  <jetty:connector name="jettyConnector">
    <jetty:webapps directory="${app.home}/webapps" port="8083"/>
  </jetty:connector>


Cheers,

Timeout blocking outbound endpoint

David Borja — 2012-05-05T16:36:08

Hi all,

I am facing a problem with ALL router.

I have configured an ALL router with three outbound enpoints. One of them
is throwing a SocketTimeout and this makes the other two stop working.

How can control the exception without affecting the behaviour of all
processor chains in ALL router?

Here is my config file:

        <all doc:name="All">
            <processor-chain>
                <http:outbound-endpoint exchange-pattern="request-response"
                    method="GET" address="${address1}"
connector-ref="HTTPDefaultConnector"
                    keep-alive="true" doc:name="Outbound1">
                </http:outbound-endpoint>
                <byte-array-to-object-transformer
                    doc:name="Byte Array to Object" />
            </processor-chain>

            <processor-chain>
                <http:outbound-endpoint exchange-pattern="request-response"
                    method="GET" address="${address2}"
connector-ref="HTTPDefaultConnector"
                    keep-alive="true"

Setting threads

Mohit Anchlia — 2012-05-02T12:00:05

How are threads organized in mule? Is it per http endpoint?

Also, how to configure threads without mmc?

Failed to delete file SampleFile.INC. Ftp error: 500

Sesharao — 2012-05-02T05:18:14

Hi All, 

i am using FileZilla Server fo FTP, 

my requirment is pick files from FTP server and write them to
'/OUT/CUSCAR/OUT/Processed' folder in FTP site and 'C:/log/in' folder in my
local system. 

if am picking file sizes lessthan 10KB every thing is fine, if file size's
like 195KB  files are not deleting from FTP Site(/OUT/CUSCAR/OUT). 

Mule is showing below error message:

Wily metrics

Mohit Anchlia — 2012-05-01T23:16:14

We use "wily" for monitoring  that helps track response times per method.
Problem with mule is that flow is generally broken down into multiple
component and thus there is no way to track response time for the entire
flow. Is there a high level class that mule uses that we can use for
tracking. Something that's used by thread as a starting point. For eg: mule
thread calls Class A, method c -> then calls user component 1,2,3. So if I
know the name of method "c" I can easily monitor on that.

Mule Tcat JSP/Servlet request to Mule ESB, then response back to Tcat JSP/Servlet

Alex Thieme — 2012-04-28T16:58:24

I apologize, but so far, this is not obvious from the documentation I've seen.

I am looking to run Mule Tcat on one server that connects to Mule ESB on another server. I am currently using Mule ESB and Jersey resources (not using Tcat, yet). That works fine for connecting to the Mule service, but I need a way to feed the Mule service response back into a JSP/Servlet (in my case, it's a JAXB2 object encoded as XML).

The bookstore example does this using CXF. I do not have nor want to use WebServices. Also, I am not sure bookstore example follows the Mule standalone deployment model I want to follow (bookstore looks to embed Mule in the war -- I want to keep these two functions distinct from one another). Also, bookstore generates HTML from within HtmlTemplate. I need to keep all view code in JSP.

Ideally, I would not have to use something like MuleClient from within JSP (or taglibs, or web controller). But, I'm open to suggestions.

I guess i need pointers to relevant example code and configuration, incl.

encode JAXB2 annotated object and write the resulting XML string to a file

Alex Thieme — 2012-04-27T00:34:55

Step 1. I have followed this page and successfully decoded an XML file into the corresponding JAXB2 annotated object (using the < at >Payload annotation). Using mule-module-xml, I don't need to add transformers into the Mule Spring XML config, which is nice.

Step 2. However, I don't know how to encode the JAXB2 annotated object and write the resulting XML string to a file outbound endpoint. Note, the file used in Step 1 is no longer available (so I can't simply write the file contents).

Any help you can provide would be greatly appreciated.

Implemeting request response with JMS

Mohit Anchlia — 2012-04-22T22:32:51

How is generally mule used to implement request response with JMS?

http://activemq.apache.org/how-should-i-implement-request-response-with-jms.html

Best practice seems to be to use correlation id for the responses but not
sure if there already is a way in mule.

Asynchronous services using http

Mohit Anchlia — 2012-04-20T17:46:03

Does mule support some kind of callback method when using asynchronous http
endpoints? Or is there a way to design this in mule?

How can i use single DB Connection in between multiple flow's.

Sesharao — 2012-04-12T06:03:45

Hi All,
Is there any possibility to share singel data base connection in between
multiple flow's?

returning reason for filter failure to user

Mathews, Benjamin L — 2012-04-05T16:59:49

We use filters in a number of places to validate the input. When the
filters fail, I'd like to provide the user with some indication of why
we aren't going to process their request. However, the filter mechanism
is set up to only return true or false for continue or not. I could
throw an exception, but this seems like an abuse of the design. 

 

What is the preferred pattern to validate input and inform a user why
the input is invalid?

 

If it matters, the specific case I'm looking at is ensuring that
incoming xml matches a schema with the schema-validation-filter. I'd
like to return error messages when appropriate like:

*         Input was not XML

*         No input supplied

*         Xml did not validate against XYZ schema because ....

 

Thanks,

 

Ben Mathews

Pattern for processing files.

colonelx — 2012-03-29T11:32:34

Hi,

I've a requirement to process a number of different files from a number of
different sources.
Eg:
EMail / ftp / sftp / NFS shares / 

Each of these files will probably have to be processed differently. (eg
Parsed as XML or parsed as CSV etc)

I'm just wondering whether the following "pattern" would be the best way to
deal with this.

I would define a flow for each of the relevant methods of transfer
eg:

<flow name="emailTransfer" doc:name="emailXFer">
     <imap:inbound-endpoint..../>
</fow>
.......
.......
<flow name="fileXFer" doc:name="fileXFer">
        <sftp:inbound-endpoint...../>
</flow>



Each of these flows would save their files to a common local intermediate
directory. 
I would then have another flow with a choice router built in to process the
files in this intermediate directory based upon their name.

      <flow name="dirReader">
    <file:inbound-endpoint path="/myDirectory"/>
     <choice>
    <when expression="/element/< at >name = 'orders.xml'" evaluator="xpath">
      <jms:outbou

Flow with jersey in and multiple outputs

Alex Thieme — 2012-03-27T18:34:31

I have seen other discussions on this point, but nothing stands out as answering my question. I need to define a flow (actually, a series of flows) that take input, then output to multiple endpoints. The initial flow received an HTTP/REST call, should do some component level processing, then return a response back to the call. In addition, the component creates an object that's put onto a queue for further processing The response back to the client should be a status message in JSON. 

Here's some config I have been playing around with. In this example, service.request must receive the REST call, create a POJO, route that POJO to the queue.create queue, then return a JSON response back to the caller. The JSON response should not be the same object as the POJO (i.e. it's another POJO).

<flow name="service.request">
        <inbound-endpoint address="http://localhost:666/api" exchange-pattern="request-response" responseTimeout="1000"/>
        <jersey:resources>
            <component>
                <single

Router proxy

Mohit Anchlia — 2012-03-21T20:49:13

Is there a component that does http proxy as well as routing based on some
http header expressions? We need capabilities of proxy but also need to
route without changing http headers

Problems using Mule 3 transport archetype

Alex Thieme — 2012-03-21T14:08:21

I am having problems running the Mule transport and hope you might have some answers.

Here's what I added to me settings.xml.

    <pluginGroups>
        <pluginGroup>org.mule.tools</pluginGroup>
    </pluginGroups>

through my attempts, I do see various versions of the transport archetype in my local Maven repository.

Amazon EC2 with Mule ESB

Alex Thieme — 2012-03-20T18:45:10

Is there a connector available for EC2? I would need to add/remove security groups, add/remove instances (spot, reserved, etc), etc. If so, then can you provide a simple configuration example to incorporate into a Mule ESB flow. Inbound endpoint can be anything, then use that data to perform actions against the EC2 API. Also, I need the correct Maven repository, plugin and dependency settings.
