i'm a newbie to Java and also to Linux
i can't run compiled java programs in Linux
'm using Mandrake Linux 9.0
the error is as follows
java.lang.ClassNotFoundException : JabberWock/class
at java.lang.Class.forName(Class.java:native)
at java.lang.Class.forName(Class.java:59)


I set the path for jdk
Now the error is
Exception in thread "main" java.lang.NoClassDefFoundError : JabberWock/class
this is exactly the same error i got in WindowsXP!!!
please help

You either need to set the CLASSPATH environement variable to include the directory that has JaberWock.class or you need to use the -classpath flag when you run the program...

java -classpath /directory/path/JabberWock.class

Setting your PATH to inlcude the j2sdk/bin directory is not sufficient.

i tried java -classpath "\mnt\G\Developers\j2SDK1\MyCodes" Jabberwock.class
but same error .....
Exception in thread "main" java.lang.NoClassDefFoundError
" I also tried this code in Windows platform in my computer and there also same error ....but i can run this on a computer in my Lab"

What version of java are you using, the newest version is a bit broken.

A couple of possible nitpicky things:

For Linux the path slash is / not \ (that is the DOS way). So if you did enter \mnt\G\... Linux isn't going to recognize it as a valid path. The quotes may also be confusing it.

If you are trying to run JaberWock.class and are in the same directory as JaberWock.class you might try this:

java -cp . JaberWock.class

If you need to add more paths to pick up other classes you could try

java -cp .:/path/class:path/anotherclass JaberWock.class

The fact that you are having the same problem in both Linux and XP suggests it is a classpath problem. You just aren't specifiying where things are correctly. As an additional resource for Java issues (and LOTS of examples) try this website

Yeah thanx man ....now itz working

It all depends on the organization of your code, if you are using packages, than you need to set the classpath, otherwise you shouldn't need it.
