How to integrate Eclipse Portable with Java Portable?

问题

I recently downloaded Eclipse Portable to do some Java Programming anywhere. I also downloaded Java Portable.

How can I integrate Java Portable with Eclipse Portable?

I know that on the "installed" version of these two, I need to set up the CLASSPATH, PATH and JAVA_HOME variables in order to use the Java Compiler(javac.exe)

How can I set this up on a thumb drive? How can I tell Eclipse to use my portable Java?

Please help me, and if possible please be specific and detailed procedure-wise. I am planning to deploy these applications on Windows XP/7 machines.

Any efforts to answer my question will be greatly appreciated!

The following instructions use the folder /apps as an example, but any folder should work.

Download and install Eclipse Portable to any folder. (64 bit or 32 bit)
Download and install the Portable Java Runtime Environment
- For 64 bit users: Install Java Portable (64 bit) to /../CommonFiles/Java64
- For 32 bit users: Install Java Portable (32 bit) to /../CommonFiles/Java
Open your Eclipse settings file ../EclipsePortable/App/Eclipse/eclipse.ini
Set the -vm as your portable Java installation. (Must be placed before -vmargs)

For 32 bit

 -vm
 E:/Apps/CommonFiles/Java/bin/javaw.exe

For 64 bit

 -vm
 E:/Apps/CommonFiles/Java64/bin/javaw.exe

Actually you should install it from within the program itself. I followed this post by berny23 and it worked perfectly (nothing else worked).

You just need the normal java runtime environment and not the

putting the files into the jre folder do this:
- Run Eclipse Portable
- Go to "Help" -> "Install new software"
- Select your eclipse version by clicking the small arrow next to "Add"
- search for "java" in the search bar
- Tick "Eclipse Java Development Tools" and hit finished.
- after installation click on "restart eclipse"
