Thank you for answering.
tags into jboss-portlet.xml and into portlet.xml also
(jboss-portlet.xml is a copy of portlet.xml)
didn't help unfortunatly.
I searched hibernate forums and docs for my PropertyAccessException, but didn't find anything other then people pointing to bugs in hibernate or to things I have done.
The end of my stacktrace is:
The end of the above mentioned stacktrace is:
| Caused by: java.lang.IllegalArgumentException: object is not an instance of declaring class
| at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
| at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)
| at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
| at java.lang.reflect.Method.invoke(Method.java:585)
| at org.hibernate.property.BasicPropertyAccessor$BasicGetter.get(BasicPropertyAccessor.java:145)
| ... 213 more
And line 145 of the BasicPropertyAccessor.java is:
return method.invoke(target, null);
it seems that BasicPropertyAccessor is invoking a method of a different class then the object in the first argument?
I don't know if the source of my problem is:
- in my code
- in my config (xml) files
- in the hibernate config files
- in the hibernate implementation
- in the Jboss config files
- In the Jboss portal config files
Or just some random bug created by for exampla a corrupted file somewhere.
Naturally I'd think the problem is in my code, but I haven't seen anyone having the same problem, which would in case of a newbie code.
Anyone see anything relevant I can clutch onto?
