I simply do this in a static method of a class: File f = new File(Environment.getExternalStorageDirectory(), "map.xml"); XStream xStream = new XStream(new DomDriver()); &lt; at &gt;SuppressWarnings("unchecked") TreeMap&lt;String,Object&gt; map = (TreeMap&lt;String,Object&gt;) xStream.fromXML(f); and then I use the values from the TreeMap with no problems... the first time. The thing is, if I invoke the method for a second time, it doesn't matter if I do it just after the first execution or after a while, I get this: 05-24 08:33:53.404: E/AndroidRuntime(15543): FATAL EXCEPTION: main 05-24 08:33:53.404: E/AndroidRuntime(15543): com.thoughtworks.xstream.converters.ConversionException: null : null 05-24 08:33:53.404: E/AndroidRuntime(15543): ---- Debugging information ---- 05-24 08:33:53.404: E/AndroidRuntime(15543): cause-exception : java.lang.NullPointerException 05-24 08:33:53.404: E/AndroidRuntime(15543): cause-message : null 05-24 08:33:53.404: E/AndroidRuntime(15543): class : java.util.TreeMap 05-24 08:33:53.404: E/AndroidRuntime(15543): required-type : java.util.TreeMap 05-24 08:33:53.404: E/AndroidRuntime(15543): converter-type : com.thoughtworks.xstream.converters.collections.TreeMapConverter 05-24 08:33:53.404: E/AndroidRuntime(15543): path : /tree-map 05-24 08:33:53.404: E/AndroidRuntime(15543): version : 0.0 05-24 08:33:53.404: E/AndroidRuntime(15543): ------------------------------- 05-24 08:33:53.404: E/AndroidRuntime(15543): at com.thoughtworks.xstream.core.TreeUnmarshaller.convert(TreeUnmarshaller.java:79) 05-24 08:33:53.404: E/AndroidRuntime(15543): at com.thoughtworks.xstream.core.AbstractReferenceUnmarshaller.convert(AbstractReferenceUnmarshaller.java:65) [...] 05-24 08:33:53.404: E/AndroidRuntime(15543): Caused by: java.lang.NullPointerException 05-24 08:33:53.404: E/AndroidRuntime(15543): at java.util.TreeMap.find(TreeMap.java:277) 05-24 08:33:53.404: E/AndroidRuntime(15543): at java.util.TreeMap.putInternal(TreeMap.java:240) 05-24 08:33:53.404: E/AndroidRuntime(15543): at java.util.TreeMap.put(TreeMap.java:186) 05-24 08:33:53.404: E/AndroidRuntime(15543): at java.util.AbstractMap.putAll(AbstractMap.java:381) 05-24 08:33:53.404: E/AndroidRuntime(15543): at com.thoughtworks.xstream.converters.collections.TreeMapConverter.populateTreeMap(TreeMapConverter.java:150) [...] with the same file.

I could also change the javascript processing of the json string, but the new version looks strange to me. I try to serialize the following object tree: class userlist { private List&lt;User&gt; users; } class User { private name; private vorname; } After the upgrade the json string contains collections at two different levels. Old {"userlist":{"users":{"user":[{"name":"x","vorname":"y"},{"name":"x","vorname":"y"}]}}} New {"userlist":{"users":[{"user":[{"name":"x","vorname":"y"},{"name":"x","vorname":"y"}]}]}} Is this ok and i should change my code? or is this a bug?

Is there some way of generating a structure like this for Map Java objects? Thanks a lot. </pre> Pablo Pazos 2012-05-11T00:58:15 http://comments.gmane.org/gmane.comp.java.xstream.user/8119 <pre>As part of going from xstream 1.3.1 to xstream 1.4.2, I'm trying to make use of HibernateProxyConverter. So I've changed the xstream configuration from, in 1.3.1: this.xstream = new XStream(); xstream.registerConverter(new JavaBeanConverter(xstream.getMapper()), XStream.PRIORITY_VERY_LOW); Mapper mapper = xstream.getMapper(); xstream.registerConverter(new HibernateCollectionConverter(mapper)); xstream.addDefaultImplementation(java.util.ArrayList.class, org.hibernate.collection.PersistentList.class); xstream.addDefaultImplementation(java.util.HashMap.class, org.hibernate.collection.PersistentMap.class); xstream.addDefaultImplementation(java.util.HashSet.class, org.hibernate.collection.PersistentSet.class); xstream.addDefaultImplementation(java.util.ArrayList.class, org.hibernate.collection.PersistentBag.class); xstream.alias("java.util.ArrayList", org.hibernate.collection.PersistentBag.class); to, in 1.4.2: xstream = new XStream() { protected MapperWrapper wrapMapper(final MapperWrapper next) { return new HibernateMapper(next); } }; xstream.registerConverter(new HibernateProxyConverter()); xstream.registerConverter(new HibernatePersistentCollectionConverter(xstream.getMapper())); xstream.registerConverter(new HibernatePersistentMapConverter(xstream.getMapper())); xstream.registerConverter(new HibernatePersistentSortedMapConverter(xstream.getMapper())); xstream.registerConverter(new HibernatePersistentSortedSetConverter(xstream.getMapper())); That more or less seems to work, with this exception: I have a java class that represents a relational table that is being serialized by xstream. But this class has some transient properties along with the usual persistent properties that map to database columns. Some of these transient properties are also java classes that I've defined. Something simple like a class that holds a name and value with a getter and setter. In my prior code, using xstream 1.3.1 and JavaBeanConverter, these contained class instances were serialized and deserialized without issue. In the 1.4.2 code, though, these properties are not serialized, they are omitted. So it would seem that HibernateProxyConverter does not handle these. I've been trying, without success, to add a second converter to handle these. I'm not sure that's the correct approach, though. In general, I could use some help, or guidance, on how best to do this.

The json output includes numbers as object names so in my example below propertyC actually has 3 nested objects but uses a number "1", "2", or "3" as the object name. In my real world the json usually contains between 100 and 200 of these (it varies). For instance: { "root" : { "propertyA " : "valueA", "propertyB" : "valueB", "propertyC" : { "1" : { "propertyC1" : "propertyC1_1_Value", "propertyC2" : "propertyC2_1_Value", "propertyC3" : "propertyC3_1_Value" }, "2" : { "propertyC1" : "propertyC1_2_Value", "propertyC2" : "propertyC2_2_Value", "propertyC3" : "propertyC3_2_Value" }, "3" : { "propertyC1" : "propertyC1_3_Value", "propertyC2" : "propertyC2_3_Value", "propertyC3" : "propertyC3_3_Value" } }, "propertyD" : "valueD" } } Can someone point me in the direction of what I'd have to do to make this work so that I could have the json deserialized into Java objects. I thought I'd have the Root object with it's simple properties/fields for propertyA, propertyB, and propertyD and a collection of propertyC but then I don't know how to configure a converter and/or aliases to handle the "1", "2","3" , etc all as the same object. I'd like to build 3 objects of the same type and where it has an extra property that really represents the object name (the 1, 2 or 3, etc). Are there some advance aliasing, converter and/or other tricks I could use to make this reasonable with xstream and jettison or should I look into other json converting utilities? I don't want to "preprocess" the json string to change its format. Thanks!

The marshalled FruitBasket object has: &lt;apples class="list"&gt; &lt;apple&gt;....&lt;/apple&gt; &lt;apple&gt;....&lt;/apple&gt;&lt;/apples&gt;&lt;oranges class="list"&gt; &lt;orange&gt;....&lt;/orange&gt; &lt;orange&gt;....&lt;/orange&gt;&lt;/oranges&gt; In order to get rid of the class="list" in apples and oranges, I added xstream.alias("apples", List.class, PersistentList.class);xstream.alias("oranges", List.class, PersistentList.class); The objects are marshalled all right, without the class= attributes. But the client unmarshals, and fails with com.thoughtworks.xstream.mapper.CannotResolveClassException: oranges If I change the order of aliasing with oranges first instead of apples:xstream.alias("oranges", List.class, PersistentList.class);xstream.alias("apples", List.class, PersistentList.class); then the CannotResolveClassException comes for apples. Seems like at most one collection of the same interface type (List in this case) is end-to-end marshalled / unmarshalled all right for the FruitBasket container class. I would like to know if there is a way around the problem. </pre> Amit Basu 2012-04-29T19:31:56 http://comments.gmane.org/gmane.comp.java.xstream.user/8104 <pre>Hello, I am new to XStream, I got 95% of my task done in nearly no time, but now I am stuck with trying to serialize the following class: class MyClass { private String name; private Pattern pattern; // few more fields private ColumnPrinter&lt;?&gt; printer; } The printer can be an instance of any subclass (possibly anonymous) of the ColumnPrinter interface.

I just wanted to share a problem I had recently and how I solved it. It seems to me the solution is unintuitive and hard to find. This maybe isn't a bug, but at the very least I think it should be easier to do what I needed to do, or maybe his needs to be a FAQ or something. So here's my story: I noticed my dates were not being converted the way I wanted. After much searching I found this: http://jira.codehaus.org/browse/XSTR-116 Ah hah! that's all I need to do! - first comment: that should be a FAQ or something. ISO8601 dates are pretty widely accepted as standard for XML, right? If they don't work automatically, it should be easy for people to figure out how to make them work, and I think the FAQ is the right place for that. So I installed Jodatime, registered my converter and thought I was done with it. But I wasn't. Unbeknownst to me, my persistence engine was converting my java.util.date objects to java.sql.timestamp objects.... sometimes. One solution, of course, was to manually change that, since I was using different objects for persistence and XML conversion, but that seemed error-prone. Not a good solution. SO I thought the right was would be to make XStream handle this. The problem was here: public class ISO8601DateConverter extends ISO8601GregorianCalendarConverter { public boolean canConvert(Class type) { return type.equals(Date.class); } ... } The date converter was only handling java.util.Date classes and not subclasses. Was that intentional? I don't know, but my solution was to do this: public static ISO8601DateConverter DATE_CONVERTER = new ISO8601DateConverter() { &lt; at &gt;Override public boolean canConvert(Class type) { return Date.class.isAssignableFrom(type); } }; That worked! horray! Now java.util.Date AND ALL SUBCLASSES are converted to ISO8601 dates, like I wanted. - Second Comment/question: Is this a bug, or was that intentional? If it was intentional, is my subclassed cade safe? Now here's the problem I don't really understand: the timestamp objects still converted like this: &lt;cTime class="sql-timestamp​"&gt;2012-03-17T20:44:00.490Z&lt;/cTime&gt; So the date/time format is right, but the class annotation confuses XStream when trying to deserialize this. The solution, which was counterintuitive to me, was this: XStream xstream = super.createXstream(mediaType); xstream.addDefaultImplementation(java.sql.Date.class,java.util.Date.class); xstream.addDefaultImplementation(java.sql.Timestamp.class,java.util.Date.class); xstream.addDefaultImplementation(java.sql.Time.class,java.util.Date.class); xstream.registerConverter(DATE_CONVERTER); That gets rid of the pesky annotation, although I suppose some other subclass could come along and mess things up. - Third comment/question: Is this the best way? Am I missing something? If this is the best way, I think there should be a better way as this is unintuitive and potentially error prone if another date subclass comes along.

That Map contains the same reference to X. I want it to ignore the Map so that it never explodes it while it is finding the fields it needs to consider for serialization. Is there a way to do this? As near as I can tell, XStream considers all of the fields in a class, even if you omit it from the output. This came from seeing those fields being considered in AbstractReflectionConverter while stepping through the code. Further, the omit appears in the code to only be considered during output. Should I implement my own converter? By the way, this problem yields an OutOfMemoryError due to non-stop recursion. I'm using version 1.2.2 of XStream. </pre> Eric Lentz 2012-03-20T14:43:30 http://comments.gmane.org/gmane.comp.java.xstream.user/8045 <pre>Hi, I've post this issue: https://jira.codehaus.org/browse/XSTR-696 But I don't know if this is an issue or something that I'm doing wrong. I think that it is an issue, and for that I've create the jira issue. I've a generic pojo, ResulBean&lt;E extends Serializable&gt; that has a property, E bean. When E is an ArrayList&lt;GnNode&gt; the output is something like this: {"&lt; at &gt;id": "1","bean": {"&lt; at &gt;class": "list","&lt; at &gt;id": "2", "org.kyrian.entity.gnomo.GnNode": {"&lt; at &gt;id": "3","nodeId": 1,"nodeTitle": "nodo 1"}, "org.kyrian.entity.gnomo.GnNode": {"&lt; at &gt;id": "4","nodeId": 2,"nodeTitle": "nodo 2"} } } But I think the output must be something like this: bean:[ {"&lt; at &gt;id": "3","nodeId": 1,"nodeTitle": "nodo 1"}, {"&lt; at &gt;id": "4","nodeId": 2,"nodeTitle": "nodo 2"} ] I'm doing something wrong?
