For more information see Sun's Java tools documentation.

In fact we maintain several different releases of Java and have made it straightforward for you to select which version of Java you wish to use. The table below shows which versions are available. You can control which version of Java you get by setting the JAVAVER environment variable to the appropriate value. If you do not set JAVAVER you will get the default version of Java (currently 1.6.0_17).

Java Documentation

We maintain a local copy of the Java documentation at SLAC. In keeping with Sun's documentation redistribution policy this copy is only accessible from inside SLAC. Other users can access the documentation from Sun's web site.

In addition a selection of O'Reilly Java books are accessible online at SLAC.

Mailing List

There is a very low volume mailing list for announcements concerning Java at SLAC. Questions about using Java at SLAC can also be sent to this list.
