Hi, I'm developing web based application with GWT toolkit. I have
client and server part. On server part, I have class for managing of
connection to JMS server for listening to JMS topic. I don't find
better way than periodically send request from client to server. On
server I have saved last message from JMS topic. I get this message
and I send it to client. This application runs on tomcat server. I use
JAXB for mapping JMS messages to Java classes, which are generated
from xml files.
I create connection to JMS server while initilalizing server part. I
have problem while undeploying. If I undeploy application, I have
error message on tomcat log and every client (web browser), which is
connect to application in the same time will be "freeze".
Exactly, I don't know when I should call closeConnection from JMS
sever. Is there any method or exception, which is call when
application is undeploying? I think, this is my problem.
Thanks for your help. I know, that it's complicated, so If you have
any additional question, please ask.
Stacktrace from log from tomcat server:
