java-execution only works if CLASSPATH is empty - why???

[Robert Jaeger]

Hi!
This is a weired thing.
If I set
CLASSPATH j2sdk1.4.0_01\lib\tools.jar
the execution of test.class (which I successfully compiled from test.java) doesn�t work (The class cannot be found!)
If I leave the CLASSPATH empty, it works!!!
That is weired.
Unfortunately I want to add jdom.jar to my classpath, if I do that the execution of test.class doesn�t work anymore.
Another problem/question: Where do I have to put jdom.jar that it can be found? I put it in c:/j2sdk1.4.0_01/lib, but during compilation the packages that shoud be imported cannot be found.
Weired, too!
Someone can help me?

Set your classpath to the subdirectory that contains your class after you compiled it with javac.

So if you have a subdir like C:\java that contains MyClass.java and you compile it with

javac MyClass.java

then you now have C:\java\MyClass.java and C:\java\MyClass.class

Your classpath should include C:\java

You can add a jar file to C:\j2sdk1.4.0_01\jre\lib\ext
