How to run Eclipse from your USB key?

Having a runnable copy of Eclipse on your USB drive is very handy. Here is how to set up Eclipse + JDT on your USB key. It assumes that your USB key is inserted as F: 
 Prepare Eclipse 
 
 Download Eclipse Platform and JDT from http://www.eclipse.org/ 
 	 Extract the content of the two files to the directory “F:\Eclipse” 
 
 Prepare JDK 
 
 You have to have Java Development Kit ( JDK ) installed on your computer first. Get JDK from http://java.sun.com 
 	 Suppose JDK is installed at “C:\ JDK ”, copy the content of the directory “C:\ JDK ” to the directory “F:\ JDK ” 
 
 Create a start-up batch file 
 You could type the following commands every time you want to start Eclipse, or (highly recommended!) save the following commands to the file “F:\eslipse.bat”. Then you just need to double-click this file to start Eclipse. 
 @echo off set JAVA_HOME=“\ JDK ” set ECLIPSE_HOME=“\Eclipse” set PATH =%JAVA_HOME%\bin;% PATH % ECLIPSE_HOME \eclipse.exe 
 Done
