Re: From JDK1.1.3 to JDK1.1.7

[Bill Glover]

The most typical way I would imagine is to extract the 1.1.7 archive into a
directory like /usr/jdk1.1.7 then create a link named /usr/java which points to
it. Change all of your classpaths and environment variables to use the
/usr/java link instead of /usr/jdk1.1.3 or whatever your current path is.

If you have problems with 1.1.7, you can then just change the single link to
point back at the old path, or when 1.2 comes out you can repeat this process
in just a few seconds.

Hope that helps.
