When I add an external class path to my WebDynPro project deploy and run the application everything works fine until i construct an object from the external class. The error I recieve is [java.lang.NoClassDefFoundError]. I'm using SP15 in the IDE as well as the server. I've tried rebuilding, removed the classpath and added it back again.
Also, the code is executed in the initialize() method inside a view. Any help is appreciated.
Thanks,
Chiedu

Problem solved. I placed the external jar and or zip class files into the lib folder within the project.
Thanks for the suggestions.

Hey Chiedu,
In your WebDynpro Configuration (for running and debugging), go to the Source tab.
Uncheck the user default source lookup path.
Then click the "Add External JARS" button and add your external jar.
Then deploy and re run/debug your application.
Happy Debugging
Sumit.

Hi Sumit,
I unchecked the default path and added the external jar and even a zip of the same file also and I'm still getting the same outcome after the program is comipled, deployed and run until i call that needed external class.
Here is the error:
