Setup remote debug with WebLogic and Eclipse
As always there is the clean way, and the one-off way.
We will see how to setup debug for weblogic using the clean way which is to leverage all the built-in items already present but not clear that they are.
<domain>/bin/setDomainEnv.sh has interesting items:
- First there is the debugFlag="true"
- Then there is DEBUG_ PORT="8453"
- Then you will also see:
JAVA_DEBUG="-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=${DEBUG_PORT},server=y,suspend=n -Djava.compiler=NONE
So the clean answer lies somewhere between these three. Also while there is the command line option as well (as you can see at the bottom of the setDomainEnv.sh).
Note: In production mode the debug is disabled by default by unsetting the flag. We can however get around this by re-setting the flag after this piece of code.
So here are the steps
Set the debug Flag
After around line number 203 in setDomainEnv.sh add the lines (ignore echo if you don't want the noise). This will also get around the production mode issue mentioned aboveAdd after this block (around Line 203):
if [ "${PRODUCTION_MODE}" = "true" ] ; then debugFlag="false" export debugFlag testConsoleFlag="false" export testConsoleFlag iterativeDevFlag="false" export iterativeDevFlag logErrorsToConsoleFlag="false" export logErrorsToConsoleFlag fi
echo "Setting debug flag" export debugFlag="true"
If you are not using just the Admin Server:
If your deployment is using a specific managed server, then you can modify the above as:if [ "${SERVER_NAME}" = "mgdserver1" ] ; then echo "Setting debug flag for mgdserver1" export debugFlag="true" fi
If you have to remote debug more than one managed server
The above block also allows you to specify a different port number for this server. And you can duplicate the same block for each of your servers if needed.if [ "${SERVER_NAME}" = "mgdserver1" ] ; then echo "Setting debug flag for mgdserver1 and port to 8454" export debugFlag="true" export DEBUG_PORT="8454" fi
Eclipse setup
In Eclipse the setup is simple.- Right click on the Project containing the deployed items. Select "Debug as">"Debug Configurations"
- Locate "Remote Java Application" in the list on the left
- Create a new configuration with hostname and debug port of the weblogic server
