Posted by: why Posted on: 2006-10-29 21:29 Tell us where your JDK folder is. If it is D:\j2sdk then SET JAVA_HOME=D:\j2sdk SET PATH=%JAVA_HOME%\bin;%PATH% SET CLASSPATH=.

閣下把甚麼放在%JAVA_HOME%\lib呢?
如果沒有, %JAVA_HOME%\lib又有甚麼用呢?

IT_layman:
那些問題敝人不打算費時間詳覆
那些%号是干吗用的啊? Microsoft batch script's syntax for "variable"
区分大小写吗? nope, but you'd better keep it
CLASSPATH呢? why don't you try but typing?

You could check your PATH and CLASSPATH with
> echo %PATH%
> echo %CLASSPATH%

And yes, you would want to put the SET statements in a batch file and execute it within the Command Prompt window
