When you’re debugging a Java Web Start client, it can be useful to get the Java Web Start Log.
This is actually quite easy to accomplish:
- Go to your Java Control Panel (on Windows: Control Panel -> Java)
- Click on the tab Advanced
- Under the debugging heading, enable Enable Tracing and Enable Logging
- Under Java console, choose Show Console
Now you can launch your Java webstart application again by clicking on the JNLP file, and you’ll get the logging in the Java console.
