Aleksander, It is much better if you ask questions as you encounter them. Asking a lot of different questions in one big email tends to turn people off (too much to approach).
I suggest you take the email and ask some very specific questions in the online forums. If you are getting an error post the exception message and the core part of the stacktrace (the inner most exception). If you have reproducible test cases post a bug report at sourceforge. I'll attempt to answer some of your questions and comments.

This comment is too vague to offer any help. You need to find out where the code is hanging. There are several places where this can happen if the application is not configured correctly. > 4. ejbPostCreate methods not called, relations not set . What kind of bean. I have never not had ejbPostCreate called. There was a bug in 3.0 that caused the UPDATE statement not to be called after a finder. This has been fixed in 3.0.1. > 5.

If I remember correctly, you are not allowed (by the Servlet spec) to redirect after data has been written to the output stream. > Despite this errors, that we are trying to isolate, we are rather satisfied > because of various problems we have already solved : > > a) Migration from remote to local interfaces > b) EJB-QL clarifying > c) Some Oracle issues > d) XDoclet works for the whole app OK.

Again, I suggest you break up this email and post them along with better details to the JBoss online forums. -- xxxxxxxxxxxxxxxxxxxxxxxx Dain Sundstrom Chief Architect JBossCMP JBoss Group, LLC xxxxxxxxxxxxxxxxxxxxxxxx ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Bringing you mounds of caffeinated joy. http://thinkgeek.com/sf _______________________________________________ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
