To compile java programs on strauss:


Type 
  java -version

to see which version of Java you are using.  If you don't like the
one shown, then do:

  ls /usr/jdk*

to list all the versions available.

Then, edit your .localenv file (this assumes you are using tcsh or csh;
directions will vary for bash, but the idea is similar) and insert the
following (selecting the appropriate /usr/jdk___ version in place of 
/usr/jdk1.5):

if -d /usr/jdk1.5 then
  setenv JAVA_HOME /usr/jdk1.5
  setenv NEWPATH $JAVA_HOME/bin:$NEWPATH
  setenv MANPATH  $JAVA_HOME/man:$MANPATH
endif

Make sure the file ends with a blank line.
If you log out and log in again, then you should have the version
of Java you want.

If you have a really "messed up" .cshrc and .login file from years
of messing around with it, this might not work.  Equally, this wont
work if you have NO .cshrc and/or .login file.  

In that case, you can execute the following shell script to start over
with a fresh copy with all the latest correct paths:

   ~consult/proto/setup

This will back up your current versions of .login, .cshrc and .localenv
with the current date appended to the end, so you can go back in and retrieve
all your favorite aliases and customizations.
