StackOverflowError when invoking WADL generator
When requesting a WADL from my service running CXF v2.4.6, I get the
following exception:

I'm not using MatrixParam annotation or enum values, so it's not CXF-2908.
Has anybody seen this before?

I've resolved after adding a check for recursive complex properties - as
I said I could not reproduce with the info you gave me but the only
thing I can think of that can cause it is having one of the complex
properties recursing...
Cheers, Sergey

I've no luck reproducing it, I really need complete (sample) Foo & FooTO
and possibly other generated classes FooToo depends upon (DateTime ?).
Alternatively, please try to eliminate individual Foo or FooTO
properties (at the schema level for ex) before regenerating it in order
to narrow down the property which causes it...

Can you add the following to your jaxrs:providers section and see if your
testcase still works?
<bean class="org.apache.cxf.jaxrs.model.wadl.WadlGenerator">
<property name="applicationTitle" value="FooService"/>
<property name="singleResourceMultipleMethods" value="false"/>
<property name="addResourceAndMethodIds" value="true"/>
</bean>

I've done a quick test by using a bean class which extends the other
bean class and it works, so obviously something in the classes you work
with causes it. It is definitely not JAXB annotations...
So we have
public class Foo extends com.foo.FooTO {
//....
}
public class FooTO {
//...
}
Something in Foo or FooTO causes the generator to recurse indefinitely...
Please post more concrete samples
Thanks, Sergey

Sorry, the return type of the method is FooResult, not Foo. The method is
_not_ using Foo as a method parameter and as the return type.

Hello Sergey,
I tracked down the cause for the stack overflow. Here are the relevant
pieces of code. The method signature that's causing it is the following
(with type names changed to protected the innocent):
@GET @Path("/foo")
Foo foo(@QueryParam("") Foo foo);
Foo.java:
public class Foo extends com.foo.FooTO { ... }
FooTO.java:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
...
})
@XmlRootElement(name = "foo")
public class Foo
FooTO is generated by JAXB from an XSD which I reference in the
jaxrs:schemaLocations section of my bean configuration file. I replaced
FooPreview with void to rule it out as well.
Any ideas?
