remote ejb long term call fails with error 502 on client side
Hello,
we have developed an project, where all our services run in JBoss AS 4.2.3GA. Everything runs fine, all clients (JAVA-SWING) connecting the JBoss via http-protocol.
But if one service-method needs longer then approx. five minutes, then an exception is thrown on client side. But the method on server side is still running fine until the regular end.
You can see it below.
Today i tried to set greater time out values, but I could not resolve the problem.
May that is the wrong way?
It would be nice, if somebody could answer to this question.
Thanks in advance
Thomas M.
