Question

I know there’s some JAVA_OPTS to set to remotely debug a Java program.

What are they and what do they mean ?

Answer 1

I have this article bookmarked on setting this up for Java 5 and below.

Basically run it with:

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044 

For Java 5 and above, run it with:

-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=1044 

If you want Java to wait for you to connect before executing the application, replace suspend=n with suspend=y.
