I'm using netbeans 8.1 to debug a web app which is deployed on weblogic server(on localhost). However, there is no high light for the current program counter so I can't know where it's stopped. If I debug a local app, it displays correctly.
Debugging a remote web app which is stopped at the break point:
Edit: I found this Bug 188844 - Highlighting lines fails in remote debugging session, but it's for PHP, I'm not sure what is "path mapping" for java + weblogic.
Resolution:
It turned out that the project source (Project Properties -> Sources) was not correctly configured. The project contains multiple sub modules thus the source path of the sub modules are incorrect. Resolution is to load the sub module as separate projects.
