change close tags ?

juan pablo — 2008-12-04T01:37:18

hi XStream people :-) First off all, thanks to XStream, this library is really helpful to our project. thanks again. I 'm writing some converts and my xml is: ** 2 8 Test Case Radio Button ** and I need this: * * 2 8 Test Case Radio Button ** the differences is in the close node of OperationEvent. some ideas ? maybe some subString ggrrrrr ... thanks! jp

Is it possible to somehow configure the PropertiesConverter so it is able to parse the following? What I can parse now is the following: Thanks, /Henrik

References between two separate XML's

xjn — 2008-12-02T17:39:42

Hi, from the docs and samples it seems that references are only possible in one XML, but not cross-XML. Is there a way to have references between two separate XML's ? For example, i have two classes Reference and Entity : < at >XStreamAlias("reference") public class Reference { public String id; ... } < at >XStreamAlias("entity") public class Entity { public String id; public Reference reference; ... } I need to serialize object instances to separate XML-Files. I cannot use a single object-graph. < at >Test public void testEntityWithReference() { ... // setup im memory Reference ref = new Reference("ref"); Entity entity = new Entity("entity"); entity.reference = ref; assertSame(ref, entity.reference); // write to directory Map writeMap = new XmlMap(new FileStreamStrategy(directory_, xstream_)); writeMap.put(ref.getId(), ref); writeMap.put(entity.getId(), entity); // read from directory Map readMap = new XmlMap(new FileStreamStrategy(directory_, xstream_)); assertEquals(writeMap.size(), readMap.size()); ref = (Reference)readMap.get("ref"); assertNotNull(ref); entity = (Entity)readMap.get("entity"); assertNotNull(entity); // !!!! this fails !!!! assertSame(ref, entity.reference); } Thx --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email

modification done to XStream 1.3 and enhancement request

Alex Shields — 2008-12-02T14:21:32

Hi. This is Alex Shields. This email is to inform you (as requested by my boss) of a change I made to the code for XStream 1.3 and a request to the developers of XStream to make some similar change to the code permanent. Problem: We want objects to not be referred to with the xpath notation like so: "../../..". Instead, we want some objects to have an id reference that may have come from a database, for example. Basically, we want to run our Converter class methods _before_ the check that an object is already one of the parents of the current object. So it'll bypass the part in the code where the xpath references are written. Scenario (the code below is modified for brevity): 1. We have a class called Person. It looks like this: class Person { < at >XStreamConverter(SimplePersonConverter.class) public Person father; < at >XStreamConverter(SimplePersonConverter.class) public Person mother; public Family family; public String firstName; } 2. We have a Family class: class Family { < at >XStreamConverter(SimplePersonConverter.class) public Person mother; < at >XStreamConverter(SimplePersonConverter.class) public Person father; < at >XStreamConverter(SimplePersonConverter.class) public Person son; } 3. SimplePersonConverter's marshal method looks like this: public void marshal(Object source, HierarchicalStreamWriter writer, MarshallingContext context) { Person person; person=(Person)source; writer.setValue(person.firstName); } 4. We have a main method: public static void main(String[] args) { Family family; Person mother, father, son; // Make a family with 3 people. family=new Family(); mother=new Person(); father=new Person(); son=new Person(); family.son=son; family.father=father; family.mother=mother; son.family=family; son.father=father; son.mother=mother; son.firstName="joe"; father.family=family; father.firstName="stan"; mother.family=family; mother.firstName="agnes"; stdout(marshalFromObject(son)); } stdout() just writes to System.out and my marshalFromObject() method returns the xml as a String by calling xstream.toXML(). 5. main() as it is written above will output this: stan agnes joe 6. What I want to output instead is this: stan agnes joe agnes stan joe Cause of the xpaths: 1. It's in com.thoughtworks.xstream.core.AbstractReferenceMarshaller in the method: public void convert(Object item, Converter converter) This if statement does it: if (existingReferenceKey != null) { writer.addAttribute(getMapper().aliasForAttribute("reference"), createReference(currentPath, existingReferenceKey)); } Solution: (This solution is simplistic since I have only delved into the code for a few hours.) 1. I modified this interface: com.thoughtworks.xstream.converters.Converter I added this method: public boolean isCustomConverter(); 2. This idea behind the new method is that if _I_ write the Converter class, it will always return true for isCustomConverter(). If the converter is one that comes with XStream, then it always returns false. This requires that I modified all of the XStream converter classes to add the new method. For example, I changed RegexPatternConverter and ReflectionConverter and a bunch of others. 3. I modified this class: com.thoughtworks.xstream.core.AbstractReferenceMarshaller I modified this code: if (existingReferenceKey != null) { writer.addAttribute(getMapper().aliasForAttribute("reference"), createReference(currentPath, existingReferenceKey)); } To now be: if (existingReferenceKey != null && !converter.isCustomConverter()) { writer.addAttribute(getMapper().aliasForAttribute("reference"), createReference(currentPath, existingReferenceKey)); } 4. I rebuilt the xstream-1.3.jar file. (If it matters, I rebuilt it in Netbeans with java1.6.) 5. I modified my SimplePersonConverter class to have the isCustomConverter method and it always returns true. 6. After all that, I get the xml output I wanted. If the actual source code I used is requested, I could make that available somehow. Requested change to XStream: XStream could possibly make due with some modification to its annotations to allow for some "ignore graph cycle" feature. So if an object has occurred already in the graph of objects, it won't output a reference but rather use a converter. --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email

Issue implementing Serializable interface

Mark Codere — 2008-12-01T16:15:39

Hi Joerg, I am using XStream to deserialize an object from XML and I keep getting the following fail message: com.thoughtworks.xstream.converters.ConversionException: Cannot deserialize object with new readObject()/writeObject() methods ---- Debugging information ---- class : com.Request required-type : com.Request path : /work_request line number : 1 ------------------------------- at com.thoughtworks.xstream.converters.reflection.SerializableConverter.doUnmarshal(SerializableConverter.java:270) at com.thoughtworks.xstream.converters.reflection.AbstractReflectionConverter.unmarshal(AbstractReflectionConverter.java:150) at com.thoughtworks.xstream.core.TreeUnmarshaller.convert(TreeUnmarshaller.java:81) at com.thoughtworks.xstream.core.AbstractReferenceUnmarshaller.convert(AbstractReferenceUnmarshaller.java:55) at com.thoughtworks.xstream.core.TreeUnmarshaller.convertAnother(TreeUnmarshaller.java:75) at com.thoughtworks.xstream.core.TreeUnmarshaller.convertAnother(TreeUnmarshaller.java:59) at com.thoughtworks.xstream.core.TreeUnmarshaller.start(TreeUnmarshaller.java:142) at com.thoughtworks.xstream.core.AbstractTreeMarshallingStrategy.unmarshal(AbstractTreeMarshallingStrategy.java:33) at com.thoughtworks.xstream.XStream.unmarshal(XStream.java:931) at com.thoughtworks.xstream.XStream.unmarshal(XStream.java:917) at com.thoughtworks.xstream.XStream.fromXML(XStream.java:861) at com.thoughtworks.xstream.XStream.fromXML(XStream.java:853) After much digging through XStream source code, it appears that the java object I'm trying to deserialize from the XML is not being created because it's an instance of a class that implements the Serializable interface. It seems as though, a SerializableConverter is being used as opposed to the AbstractReflectionConverter. In the DefaultConverterLookup.lookupConverterForType(), the SerializableConverter is found since it's isSerializable() returns true after passing the serializationMethodInvoker.supportsReadObject() test. The object I'm trying to deserialize contains a readObject() in one of it's parent classes... Thanks, Mark

How to use XSTream to persist a Graph Object??

sunnymanman — 2008-12-01T03:38:10

I hope After I run it, I made some changes on the picture such as: rotation angle is -45 degree; Distance from the end is 100; I hope to save this CURRENT state into an XML file and save it to disk; 2. then next time I open it, I can read this XML file from disk, and recover whole picture I saved before: rotation angle is -45 degree; Distance from the end is 100; How to use XStream to do this?? Thanks

CannotResolveClassException

Wu, Calvin (Technology — 2008-11-28T00:17:57

We're using a custom SingleValueConverter to handle test. It works fine on one linux platform, but getting CannotResolveClassException on the other. com.thoughtworks.xstream.mapper.CannotResolveClassException: [Lcom.test.Category; : [Lcom.test.Category; It looks like it's failing in the realClass method of DefaultMapper: public Class realClass(String elementName) { try { return classLoader.loadClass(elementName); } catch (ClassNotFoundException e) { throw new CannotResolveClassException(elementName + " : " + e.getMessage()); } } The classLoader is trying to load "[Lcom.test.Category;" when it should be loading "com.test.Category" instead. Why is this happening? Thanks,

RegisterLocalConverter Priority

Andy Yeung — 2008-11-27T13:21:10

Hi, I have implemented an custom date converter which implements SingleValueConverter. I have also created the DateConverterWrapper which extends SingleValueConverterWrapper. Then I have used annotations on a class called Transaction < at >XStreamAlias("Transaction") public class Transaction implements Serializable { /** * */ private static final long serialVersionUID = -4068970037592154030L; < at >XStreamAsAttribute < at >XStreamConverter(DateConverterWrapper.class) < at >XStreamAlias("date") private Date date; < at >XStreamAsAttribute private String action; < at >XStreamAsAttribute private String merchantTransactionId; .... } However, I found that the custom converter is never called unless I remove the < at >XStreamAsAttribute annotation. If I register the Converter as global converter, then the date is converted using the custom converter and output as attribute. However I don't want this customized converter in global scope. Is there any ways to do this? Thanks, Andy --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email

Converting XML to Java Objects

bigblop — 2008-11-26T18:33:18

I have an XML file that looks something like this: So a block can either contain a list of data1 or data2 "objects". A block cannot contain both "objects" in the same "scope". When I want to create a class that this XML file can be converted to I do: class block { private List d1; private List d2; ... (where data1 and data2 are separate objects). But when I convert the block class back to XML I get something like: As can be seen both data1 and data2 are contained within the same block! How do I separate data1 and data2 in separate blocks without having to make two different block classes?

How to add Attributes to XML Element while creating XML from Java Object

Rick Pats — 2008-11-24T19:47:21

Hi, I am new to XStream. I need to know how to create an Attribute for a XML element. I am creating XML from Java beans. Here is what I am trying - Rick male I have a java bean class Person.java - public class Person { private String name; private String gender; private final String xmlns = "http://"; public Person(String name, String gender) { this.name = name; this.gender = gender; } --Getter and Setter Methods for properties-- } In my main class - XStream xStream = new XStream(); Person person = new Person("Rick", "male"); xStream.useAttributeFor(Person.class, "xmlns"); String xml = xStream.toXml(person); This generate the XML with out the "type" attribute for name. I am not sure how to add the attribute to a String inside Person class. Please help and advise.

How to get ObjectGraph?

rmahmood — 2008-11-24T09:59:35

Hi, I want to get the object graph maybe from serialized object or maybe object in memory. The target of getting such an object graph is to build a Jtree representing the object with all its graph for visualization and maybe later some processing. Does Xstream provides any public function which returns the objectgraph of any object passed as an argument?

[JSON ERROR]

João Kreuzberg — 2008-11-24T07:08:15

Hello Guys I believe there is something wrong with JettisonMappedXmlDriver while dealing with collections. I have the following Java class: public class State extends com.orion.model.Model { private Integer id; private String name; private Country country; private List values; .... } But when I use the JSON driver, It is putting the collection values on the root instead of keeping it inside of the State object. As you can see, on XML it all works great: Here is what I'm getting with the JSON driver: {"list":{"state":{"id":1,"name":"Parana","country":[{"id":1,"name":"Brazil"},{"id":0}],"values":{}},"country":{"id":1}},"state":{"id":2,"name":"Santa Catarina","country":[{"id":1,"name":"Brazil"},{"id":0}],"values":{}},"country":{"id":1}} As you can see, the 'values' collection does not contain any value and somehow ends up on the root of the list document as 'country'. If i use JsonHierarchicalStreamDriver it seems also works fine but it does not solve my problem since I need full serialization/deserialization. Here is a sample of JsonHierarchicalStreamDriver: {"list": [ { "id": 1, "name": "Parana", "country": { "id": 1, "name": "Brazil" }, "values": [ { "id": 0 }, { "id": 1 } ] }, { "id": 2, "name": "Santa Catarina", "country": { "id": 1, "name": "Brazil" }, "values": [ { "id": 0 }, { "id": 1 } ] } ]} Could this be some kind of bug or am I missing something?

How can I use XStream to persist only customer objects??

sunnymanman — 2008-11-22T02:26:55

Dear Friends: How can I use XStream to persist only customer objects?? when I use XStream to persist an GUI object, It save all java standard classes such as JPane, JButton, JLabel etc, it takes a lot of space, But I did not want XStream to store all common API classes, I only hope it persists the classes I created, How can I do that?? Any Example??(includes serialize and deserialize) Thanks Sunny
