Debugging a Java Application That Has a Wrapper

A Java application usually has a wrapper to set environment variables. If your Java application has a wrapper, you need to tell dbx that a wrapper script is being used by setting the jvm_invocation environment variable. For more information, see Customizing Startup of the JVM Software.
