#1509 — moving CLASSPATH

I want to move an exe 
program which uses a registry definition of java classpath

Unfortunately It does not ask for install directory so I can't use
PortableApps Launcher

I have the classpath from the registry and set it in the batch file as an
environment variable but it doesn't find it.

THis is a long shot but, Is it possible to run some Java program to specify
the classpath then run the exe?

set classpath=lib\a.jar;lib\b.jar;lib\c.jar

Should I put set myhome=.  and put myhome in front of each occurance of lib???

Terrible idea.

First, don't use CLASSPATH.

Second, "classpath" is not correct.  You only get away with it because Windows 
is lax.  It's "CLASSPATH".  But you shouldn't use it anyway.

You used relative directories.  That means that *every* Java program in that 
system must run from a directory with a "lib/" subdirectory with those three 
JARs in it if they are to run.  That's exemplary of why you should not use 
CLASSPATH.  It's too global.  Don't use it.

Use the "-classpath" (a.k.a. "-cp") option to the Java tools ("java" and 
"javac", here).

Why are you using Java if you're packaging to an EXE?

If you must use CLASSPATH, which is a bad idea, at least specify absolute 
directories for the path roots.

It's better to package your application as a JAR (which controls its own 
classpath and ignores CLASSPATH) than as an EXE.  Use the JAR format.  That's 
what it's for.  You can associate JAR files with "java" (or "javaw") to launch 
them on double-click, package them in a CMD file to make them act like native 
executables, or write a thin executable wrapper to launch the JAR.  All of 
which make it easier to shun CLASSPATH as you should.

Put everything in a jar and ignore the classpath, or put the classpath
in the jar.

If you can't remember the name of some method, 
consider changing it to something you can remember.

You can modify the registry with RegEdit.

One of the most useful comments you can put in a program is 
"If you change this, remember to change ?XXX? too".

THis is a program written in Java but supplied as an EXE.

I am trying to put it into portableapps and the classpath won't transfer

I tried portable apps creator but the EXE program's intaller insists on
putting it in ProgramFiles.

I am kinda stuck between different methods by choices someone else made

No way to just get a ZIP of the JAR and its companions?

Not a Java question.

Does your app packager let you assemble your JAR and its dependency JARs into 
one package?
