I migrate my application from JBuilder 5 & IAS 4.5 to JBuilder 8 & BES 5.2. But I have a big problem with it. I create a small EJB by JBuilder and deploy it on BES. All seem ok!! But when I launch the test client (created by JBuilder), it connects to the EJB in the probability of 25%. I have applied the path included with BES. Thank for the help.
