Hi, I'm seeing a fairly common error message, it would seem: A ClassCastException on
the narrow call after retrieving the home interface of an EJB2.
I have read all the docs saying to ensure that Isolation and CallByValue are on so the
server is J2EE 1.4 compliant. In 4.0.3SP1, that was sufficient. Unfortunately, in
4.0.5.GA, even after using the installer (default configuration) and clicking the checkbox
to turn on CallByValue, I still get the exception at the end of this message.
Do we have confirmation that 4.0.5 didn't break something in this regard? The release
notes didn't have any clue in them, and I check the XML files and sure enough they
have the right isolation settings, (i.e. the ones that worked in 4.0.3) although some
files have changed and the docs are out of date. Still, I trust the installer to set up
isolation and callByValue correctly.
Ideas? Something else I should try?
Here is the exception:
