BAT Batch Set Java JDK system environment variable file __java

You can modify the Java installation directory on line 3rd to set Java_home, ClassPath, and append to the front of the path.

Java_home=c:\program files\java\jdk1.6.0_10

Classpath=%java_home%\lib\tools.jar;%java_home%\lib\dt.jar;.

Path=%java_home%\bin; ....... Append to the top of the path (solve the problem where you should end up with a semicolon.) hehe. Leave the question to others
