The input line is too long - Windows command line error

Today I wanted to run the bat file to run a java program in Windows. This file is mainly used to set the classpath, part of the file content is shown below.
Complete file content is shows at the end.

@echo off
setlocal

set BROKER_HOME=C:/Documents and Settings/user/workspace/myProject

set CP=%BROKER_HOME%/out/lib/activation-1.0.2.jar;%CP%
set CP=%BROKER_HOME%/out/lib/activeio-2.1.jar;%CP%
...
set CP=./;%CP%
set CP="%CP%"
ECHO Using Classpath:
ECHO %CP%
cd ..
java -classpath %CP% com.mycompany.myproject.Client

An error message resulted saying "Input line is too long" as shown in the image above. This is not an error in the java program which you would guess first.

Reason for the error message

I have set up a variable for classpath which makes my command too lengthy. This message pops up since the command is too long for the Windows� command line environment to handle.

The number of characters that can be entered into a single command is limited to 8191. (this is including spaces).

For example, total number of characters in below command is 42.

javac -classpath myclasses.jar Client.java

Solution

There was no solution to the issue other than somehow making the classpath shorter by moving the jar files into a folder like "C:/jars" from initial folder at "C:/Documents and Settings/user/workspace/myProject/out/lib".

Do you have any other solutions for this issue?
