Hi, I have been debuggin thru the code and what i found that in the XMBean class the operationContextMap has a different set of data in different versions. In Version 4.0.2 the Mbean operationContextMap contains method signatures which have a both attribute and operations tags where as in version 4.0.5.GA operationContextMap contains only the operations tag. I am wondering if somebody can explain why we have this descrepency and what i can do to fix this without changing our code. One more thinh i am calling "invoke" on the MbeanServer for both attributes and operations XDOCLET tags.
