Hi,

I haved wondered what is the best way to have resources with responses only having URIs to subresources or associated resources.

For example the response of a mainresource:
-------------------
<mainresource>
        <id>1</id>
        <name>Test</name>
        <uri>http://localhost:8080/mainresources/1</uri>
        <subresources>
                <subresource uri="http://localhost:8080/mainresources/1/subresources/1" />
                <subresource uri="http://localhost:8080/mainresources/1/subresources/2" />
                <subresource uri="http://localhost:8080/mainresources/1/subresources/3" />
                <subresource uri="http://localhost:8080/mainresources/1/subresources/4" />
        </subresources>
        <associatedresource uri="http://localhost:8080/associatedsource/1" />
</mainresource>
-------------------

and the response of one subresource:

-------------------
<subresource>
        <id>2</id>
        <uri>http://localhost:8080/mainresources/1/subresources/2</uri>
        <name>SubresourceTest</name>
        <description>A description</description>
</subresource>
-------------------

I've tried many different ways, but there where always points I couldn't get further.

One try was the @Ref annotation in jersey-server-linking. But I always ended up in a loop of exceptions with the following stacktrace:
-------------------
29.11.2010 23:37:57 com.sun.jersey.server.linking.impl.FieldDescriptor getFieldValue
SCHWERWIEGEND: null
java.lang.IllegalAccessException: Class com.sun.jersey.server.linking.impl.FieldDescriptor can not access a member of class java.util.zip.ZipConstants with modifiers "public static final"

        at java.lang.reflect.Field.get(Field.java:358)

        at com.sun.jersey.server.linking.impl.RefProcessor.processMember(RefProcessor.java:120)
        at com.sun.jersey.server.linking.impl.RefProcessor.processLinks(RefProcessor.java:113)
        ...
        at com.sun.jersey.server.linking.LinkFilter.filter(LinkFilter.java:78)
-------------------
        
even if no @Ref annotations are used, only with the ContainerResponseFilter property activated.

I hope you can point me to the right direction.

Thanks
