Java Console closes too on startup, so it's impossible to see what startup error may jnlp app has. How to see its output?

Question

I'm running a Java application as a jnlp and sometimes, when a problem occurs during startup it will spit something out to the Java Console and close. But it closes so fast that I can't actually see anything at all.

Is there some way to see this log, maybe in a file on disk? Or to avoid the closing of this console window?

Thanks

You could activate the tracing in the java configuration.

advanced -> activate Tracing.

once this is done it writes Tracing files in the folder

C:\Users\user\AppData\LocalLow\Sun\Java\Deployment\log

There you could inspect what caused the error in the jnlp
