Standard and non-standard options
The HP-UX SDK for the Java™ 2 Platform tools install into either /opt/java1.2/
bin, /opt/java1.3/bin, /opt/java1.4/bin or /opt/java1.5/bin directory,
depending which SDK release you are installing. The installation process will update
your system PATH to include the appropriate directory to allow you to invoke Java™
applications.
To see the full list of java options, enter the command:
java -help
To see the full list of non-standard options, enter the command:
java -X
For more information on each option, run the following command:
java <name of option>:help
For example, to see more information on -Xrunhprof, run this command:
java -Xrunhprof:help
The HotSpot technology accepts all of the standard options as well as the following
partial list of non-standard -X and -XX options. Non-standard options are not
guaranteed to be supported on all VM implementations, and are subject to change
without notice in subsequent releases of the Java™ 2 SDK.
