Best Practices While Connecting to Weblogic 10.3.x JMS from Hermes

Based on my experience it is good to follow below rules to avoid annoying errors/exception and consequently save your time.

1. Do not create a provider by adding weblogic.jar, instead create wlfullclient.jar and then add it as a jar in your provider. From weblogic 10 onwards this is the procedure.
2. Preferably create a wlfullclient.jar from the server instance where you want to connect. That way you can avoid any version and class not found issues.
3. Note the port of T3 url. It is the listen port under servers on admin console. If you are connecting to a server with soa suite then the server to check is the managed server i.e. soa server. Usually the listen port for soa server is 8001. In this case t3://<hostname>:7001 will not work.
4. If a server is behind the firewall then the port needs to be opened in firewall for communication to work properly.
