Hi,
we use the JOnAS version 2.1.1. We develop a
client-server program and the program runs on windows NT 4.
We have a program which called from the client
session a method of the session bean. We keep the instance of the session bean
once at the beginning of the client method. Then the program runs in a loop,
a method of the session bean is called. This works correct if the loop
counter is smaller than 600 or 700. If it is greater we get an error on
Jeremie Registry. The error code is OutOfMemoryError. In a further version
of JOnAS 1.6.1 with the sun registry (RMI-Registry) the program works
correct.
An extract of the program code you can find at the
end of the eMail.
Have you any ideas to solve the
problem?
Thanks,
Michael Joos
