Destination 127.0.0.1, 7001 unreachable - Weblogic - weblogic

Question

I installed weblogic 12.1.2 and changed the port from 7001 to 8081 through console and restarted the server.
However, when I deployed my application and ran it, I am getting the below exception.
I dont understand why the server is trying to access 7001, when the listner port is 8081. Can anyone help?
javax.naming.CommunicationException [Root exception is java.net.ConnectException: t3://localhost:7001: Destination 127.0.0.1, 7001 unreachable; nested exception is:
java.net.ConnectException: Connection refused: connect; No available router to destination]

Answer 1

Is it possible that your application is accessing some application configuration you have on the server which is still pointing to the 7001 port?
You could look in the ${WL_HOME}/config/config.xml file to double check that the port has infact changed and then also do a 'netstat -an | grep LISTEN' (Linux Machine?) to see what is listening on which ports.

Answer 2

When you change port from admin console, changed port gets reflected in ${WL_HOME}/config/config.xml (atleast in my case it did), but this change is not reflected in start/stop scripts present in ${WL_HOME}/bin directory. For example:
setDomainEnv.sh
startManagedWebLogic.sh
startWebLogic.sh
stopManagedWebLogic.sh
stopWebLogic.sh
still contain old port. You will have to change search and change them manually.
