Hello. I see, that i cannoct access methods of the same bean-instance concurrently. The same method of different instances can be accessed concurrently, although i haven't tested it with jonas. What i have tested is: creating 2 instances of EJBeans concurrently which doesn't work. Jonas blocks the second call until the first finishes. Unfortunately one call to ejbcreate lasts about 2 to 10 minutes... I admit, that this may be a bad design, but even for short ejbcreate methods and heavy load, this would be a problem.. (think about a runtime of 1 second and 100 Users creating... - uhh ahh) Is this part of the Spec ? A bug or feature in Jonas ? Did i miss something deploying the bean ? thanks markus ---- To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "unsubscribe jonas-users".
