I was debugging an enterprise application at my office today and suddenly got a heap dump – so I thought of creating a new post in this blog about the location of the JVM dump file in JBoss 4.0.5 server along with the stack trace of the error (and what other files are created during dump process). My IDE is IBM’s Rational Software Architecht (RSA) and I am running my JBoss server against a JDK of 1.4.2_12.
As you can see in the stack trace below, the java dump files are located at JBoss bin folder. There were basically three files created during this dump process:
- System Dump File – core.20100830.093556.8156.dmp
- Snap Dump File – Snap0001.20100830.093556.8156.trc
- Java Dump file – javacore.20100830.093556.8156.txt
