There is one context per "web application" per Java Virtual Machine


As per servletcontext spec we will have one context per application per JVM.

My question is can we run find 2 JVM's on a single JBoss instance ?

If Yes then two servletContext will be present .

You can't have more than one JVM for one instance of JBoss AS. When you start a JBoss AS, a separate JVM is instantiated.

Does this mean JBoss will have a separate JVM internally or it will use system default.

When you start the JBoss AS, the "java" command is executed (see the run.bat/run.sh script in the bin folder). The "java" command triggers the creation of a new JVM in which the AS will run.

It will use JAVA_HOME/bin/java to start the JVM. So whatever JVM you point to, through JAVA_HOME variable, will be used.
