[mpich-discuss] Jumpshot and mpich2-1.3.3rc1

[Jain, Rohit]

Thanks for all responses.

It seems that easier way is to use --with-java=<JRE_HOME> during config.
Jumpshot picks up given JRE version by default.

Then, if you further want to override JRE version and use a different
one, you can always use one of the methods below by setting
JRE_HOME/JAVA_HOME/JVM.

Regards,
Rohit

If you don't like to type JRE_HOME or JAVA_HOME, you could define
JVM instead (As Nicolas has pointed out, there is no env variable
support of JRE in jumpshot script).

/home/chan/mpich_work/install> setenv JVM /some/version/of/jvm
/home/chan/mpich_work/install> bin/jumpshot -show
GUI_LIBDIR is set. GUI_LIBDIR = /home/chan/mpich_work/install/lib
/some/version/of/jvm -Xms32m -Xmx512m -jar
/home/chan/mpich_work/install/lib/jumpshot.jar
