[jboss-user] [JBoss Portal] - Re: Data access / persistence - could you help?

Thank you for answering. I put <trans-attribute>Required</trans-attribute> 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?
