First, you need to decide which Java version to want to be the default
command line Java and which Java versions you need to have installed for
what you want to do. This will determine what needs to change when you
install a new Java version.

Before installing anything new, there are some things you can do to
optimize your current settings.

>LIBPATH=C:\JAVA11\DLL;C:\JAVA11\ICATJAVA\DLL;C:\JAVA11\ICATJAVA\DAEMON;

This is OK, although if you never use the Java debugger, you can remove
the ICATJAVA references.

>..., SET PATH=C:\JAVA11\ICATJAVA\BIN;C:\JAVA11\BIN; ...,

Same as above. Whatever Java appears first in PATH is the default command
line Java.

>SET DPATH=C:\JAVA11\ICATJAVA\HELP; ...,

Same as above.

>SET HELP=C:\JAVA11\ICATJAVA\HELP; ...,

Same as above.

>SET CLASSPATH=C:\JAVAOS2\LIB\JEMPCL10.ZIP;.\. ...,

Change this to:

SET CLASSPATH=.\.

unless you really are still running v1.0.2.

>SET INCLUDE=C:\JAVAOS2\INCLUDE;C:\JAVAOS2\INCLUDE\OS2; ...,
>SET LIB=C:\JAVAOS2\LIB; ,,,.

See above re: v1.0.2. If you are not developing Java apps you don't need
any INCLUDE or LIB entries.

>The Java 1.4.2 directory has a BIN subdirectory. Therefore,
>C:\JAVAOS2\LIB should probably change to C:\JAVA142\LIB, right????

Unlikely. Delete the obsolete stuff from your settings and then let the
v1.4.2 installer do its thing.

>Should C:\JAVA11\ICATJAVA\BIN;C:\JAVA11\BIN go over to C:\JAVA142\BIN????

Again, unlikely.

>I don't seem to have an INCLUDE subdirectory under Java 142.

You probably didn't install the JDK. That said, the INCLUDE and LIB
entries are only needed for JINI apps. The Java compiler does not use
them in any way.

>Any help on this is muchly appreciated. Thanks.

I recommend you think of Java as just another application. Just as some
need multiple word processors installed, each with its own config.sys
settings, the same is true for Java.

Decide which Java versions you need and install them. Just as a given
word processor can only handle certain document formats, the same is true
for Java versions. Not all Java apps and applets run on all Java
versions. This is usually due to Java application bugs, but that's
irrelevant if you need to run the app.

I recommend you understand which versions you need for what you are doing
before choosing to replace one version with another.

Regards,

Steven
