Troubleshooting a Java Web Start application and accessing log files

Question

I am launching a Java Web Start application which shuts down abruptly. Does anybody know how to access the logs for Java Web Start. Are there any known reasons for it to shut down abruptly?

Answer 1

You should enable detailed trace logging as explained on this page. The same page gives you the location of the log files;

The trace file is saved into the log directory in the "Java Deployment Home" folder. That folder's location is specific to your operating system:

• Windows XP: %HOME%\Application Data\Sun\Java\Deployment
• Windows 7/Vista: %APPDATA%\..\LocalLow\Sun\Java\Deployment
• Linux/Solaris: %HOME%/.java/deployment

Answer 2

On my Windows 10 computer, the log file is found at:

C:\Users\<MY USER>\AppData\LocalLow\Sun\Java\Deployment\log
