jar problems with dom4j

807601Jun 9 2008 — edited Jun 9 2008

I want to use a jar file in my application. It is called dom4j-1.6.1.jar and is in the same directory as my java file. When I compile my application with this command:

javac -classpath /home/user/Desktop/work/dom4j-1.6.1.jar Foo.java

I get no errors or complaints. However, when I run my application. I get

Exception in thread "main" java.lang.NoClassDefFoundError: org/dom4j/DocumentHelper
        at Foo.main(Foo.java:13)
Caused by: java.lang.ClassNotFoundException: org.dom4j.DocumentHelper
        at java.net.URLClassLoader$1.run(URLClassLoader.java:200)

        at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319)
        ... 1 more

as an error. However, if I unjar the application using

 jar xf dom4j-1.6.1.jar

and then compile normally i.e.

javac Foo.java

The code runs fine. What am I doing wrong?

Thank you,
Michael
