Description

When attempting to provide concrete implementations of interfaces, as described in the last section of http://xfire.codehaus.org/Aegis+Binding, the service picked up the override types correctly. However, when it comes to writing out the types, a bean that contains a List (say) of the overridden interface wasn't overriding these types correctly. What happened was that the outer bean would call AegisBindingProvider.getWriteType(), passing in the List itself. Since this function doesn't inspect the component type of the list, it wasn't possible at this stage for it to notice the types that should be overridden. So off we go into CollectionType.writeObject(), and here it assumes that the Type of all the elements in the list is the same as the declared type.

This is incorrect; my bean had a List<IDataColumn>, so actual members of the List may be SQLColumns, DataAggregateColumns, etc. What was needed was to call AegisBindingProvider.getWriteType(), passing in each element of the list. As it turns out, the superclass ArrayType already did the right thing with its writeValue() method, so the solution seems to be to defer the actual write to this method. I attach a patch that does this, and worked perfectly for me.

I'm marking this as a duplicate of XFIRE-545, but I will be applying this patch. Thanks!

I gather from the empty "Fix Version/s" field that this patch did not make it to the 1.2 final?

This is fixed in SVN right now for 1.2.1. A build is here if you want to test:

http://snapshots.repository.codehaus.org/org/codehaus/xfire/xfire-all/1.2-SNAPSHOT/xfire-all-1.2-20060904.045024-15.jar

Thankyou! 8 minutes is what I'd call excellent response time

I tried the snapshot jar and something has changed, as the previous ClassCastException from CollectionType has changed to this:

Its your lucky day I guess - If you're using java 1.4 - did you configure your collections like the bottom of this page says:

http://xfire.codehaus.org/Mapping+collections

Or are you using Java 5? If they're java5 collections, xfire should figure them out autmotically.

I'm on Java 5 (Sun 1.5.0_07 on Debian Ubuntu), and basic collections mappings have worked all the time. I started with 1.1.1 and only now upgraded to 1.2 when the problem appeared with a new web service method.

Let's see if I can find out what is special about this failing case.

XFire might be getting confused if you aren't specificying the inner collection's component type. I.e. do you have Collection<Collection> instead of Collection<Collection<Foo>> ?

</property>
<property name="serviceBean" ref="saver"/>
<property name="serviceClass" value="com.innovit.ice.core.dao.ChangeSaver"/>
<property name="name" value="Saver"/>
</bean>

I thing the issue is not solved. As this functionality is necessary for us, please solve the issue ASAP.
Also It would be great if we have same feature for Arrays too.

I had the same problem as Behrang Javaherian;
I am using JDK 1.5 and xfire1.2.1;my bean has definition like this: Collection<Entity> newEntities;

As the bellow:

http://xfire.codehaus.org/Mapping+collections

Java5 collections, xfire should figure them out autmotically.

but error as bellow:
Caused by: java.lang.NullPointerException
at org.codehaus.xfire.aegis.type.basic.ObjectType.determineType(ObjectType.java:192)
at org.codehaus.xfire.aegis.type.basic.ObjectType.writeObject(ObjectType.java:165)

Now , I have Solved the problem:

like using java 1.4 ,configure collections like:
<mappings>
<mapping>
<method name="getCollection">
<return-type componentType="MyType"/>
</method>
<method name="setList">
<parameter index="1" componentType="MyType"/>
</method>
</mapping>
</mappings>

just do it , then ok;

reference by:
http://xfire.codehaus.org/Mapping+collections

so , i think xfire-aegis is not good supporting for jdk1.5,
not only 1.4 but also 1.5 is need for Mapping configration for collections

I have the same error with 1.2.1 when returning a List from a method with this interface...

@WebMethod
@WebResult(name = "divisions")
public List<Division> getAllDivisions();

I am using java 1.5.0_07, spring 1.2.8 and the jsr181 annotations.

I do not have this error with 1.1.2, which works fine.

Thus I cannot upgrade until this issue is resolved.

Any other alternatives? Do you guys need futher information on my interface and the webservice?

James Burton,
Did you have to provide mapping file or just swapping the jars fixed your problem. Can you explain the changes you made inorder to get the collections component working
