Problem with a package jar applet

Okay, I've just got finished porting over a swing app into an applet and have compiled it into a jar file. There is one problem when I try to run it from the browser though it says

java.lang.NoClassDefFoundError: org/apache/commons/net/telnet/TelnetClient

at MuddyApplet.ClientForm.<init>(ClientForm.java:26)

at sun.applet.AppletPanel.runLoader(Unknown Source)

at sun.applet.AppletPanel.run(Unknown Source)

at java.lang.Thread.run(Unknown Source)

That is the third party jar file that should be included already but isn't. Can someone help? I'm using netbeans.

You will need to add that 3rd party software to the classpath of your manifest file inside your own jar file: http://java.sun.com/docs/books/tutorial/deployment/jar/downman.html
