Debuging with Karaf
course you, can debug your Of application. karaf can be started by enabling the remote debug, in particular Karaf will open a socket on a specific port and ip. Eclipse can attach to karaf via socket at runtime.
You need to:
- start the universAAL release in debug mode: you can export the variable (this is done by default, it can also be added to your setenv script)
export KARAF_DEBUG=true [LINUX] SET KARAF_DEBUG=true [WIN]
- check the debug option on the script
bin/karaf.sh [LINUX] bin/karaf.bat [WIN]
Look for the following properties in the script:
DEFAULT_JAVA_DEBUG_OPTS="-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5006"
In this sample case it is 5006. In the latest version of the distro, Karaf will listen on port 5005.
- Go to Eclipse and create a Debug Configuration of type Remote Java Application
- Click on Debug
- Then put some breakpoint in your code
- Add, install and start the modules you wish to debug (as you would when running a normal karaf application)
- Eclipse will automatically stop execution where you put your breakpoint, or when pressing the stop button.
please read documentation about the debug functionality to get the maximum out of it.
