Message regarding the Java Development Kit on Athena  3/16/98
 
We have upgraded the JDK on Athena to release 1.1.5 for Athena Suns and 
test SGI O2s running IRIX 6.3 (the 1.1.5 JDK won't run on IRIX 5.3). At
the moment O2s are only available as IS Staff test machines- they will not
begin to be generally available until sometime this Summer.

To run the 1.1.5 release, add the java locker and follow the
application name with a version switch, i.e. "javac -ver 1.1.5
myapplet.java", or, if you prefer, add the java_v1.1.5 locker instead
of the java locker, which will allow you to run 1.1.5 applications
without the "-ver 1.1.5" command-line switch ("javac myapplet.java"
will then run javac 1.1.5).

After doing "add java_v1.1.5", on an SGI O2, "man java" will print some
summary information and point you to a URL 
(file:/mit/java_v1.1.5/distrib/sgi_63/webdocs/release.html) with links 
to a lot more information. On a Sun, there are separate man pages for 
most of the components (to see which are available, look in 
/mit/java_v1.1.5/man/man1).

We have tried to keep the directory structure for each platform version
as close to each vendor's original distribution as possible, and there
are small but possibly significant differences in components that would
otherwise be platform-independent. for this reason the directory
/mit/java_v1.1.5/include is an @sys AFS link to different vendor include 
directories.

The roots of the respective vendor distribution trees are below
/mit/java_v1.1.5/distrib/$ATHENA_SYS. This release will not become
the default on Athena until sometime this Summer, after the end of
the Spring Semester, though with the fast pace of Java development,
an even newer (1.2?) release may be out by then.

This message is in file /mit/java/Athena/messages/JDK115 if you want to
read it again.

Please report problems to 3partysw@mit.edu.
