When I run the successfully compiled java source shown at the end I got a runtime error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/jdom/Content

Where is the missing class ?

I copied the newest jdom.jar from newest JDOM release b10 to the folder

jdk\jre\lib\endorsed

Is this not enough ?

Bernd

org.jdom.Content is in jdom.jar.

Note that this class does not exist in some previous versions of jdom.jar
(for example the version which comes with b8 which I just checked).

Personally, I wouldn't store jdom.jar in jdk\jre\lib\endorsed. Make
certain your CLASSPATH is pointing to a valid jdom.jar file.

Hello!

I have the same problem as Bernd Oninger, I can compile but not run
the program.

Im trying to make this simple example to work...

---- example1.java ----
import org.jdom.*;

public class example1
{
public static void main(String[] args)
{
Element root = new Element("myRootElement");
Document doc = new Document(root);
root.setText("This is a root element");
System.out.println(doc);
}
}
-----------------------

To compile I use this:
>javac example1.java -classpath "jdom.jar"

....it works great since i have the jdom.jar-file in the same directory
(I asume that you can have the jar-file anywhere you want, as long as
the path is correct).

But when I run the program I get this:
>java example1 -classpath "jdom.jar"
Exception in thread "main" java.lang.NoClassDefFoundError:
org/jdom/Element
at example1.main(example1.java:7)

....why wont this work???

GIMME, when you are talking about the CLASSPATH do you mean the
enviroment variable (NOTE: Im using windows here, not linux)??? I have
tryed "set CLASSPATH ..." but its still the same problem.


THX in advance

Good. Right.

You have to have the classpath stuff up front ...

java -classpath $CLASSPATH example1

Yes. Although the syntax of separaters differ, back slashes instead
of forward slashes, in each instance you want an environment variable.

Try :

echo %CLASSPATH%


Relying on Window's environmental variables all the time can
lead to some undesirable behavior.

I use a dos batch script to set up my environmental variables
and then call cygwin. Here a sample script for you to study.
If you don't have cygwin installed delete or comment out the last
line.
