NoClassDefFoundError when project imported to Eclipse?

I am working on an app which uses Commonslang.jar libraries. I was trying to setup it on a new system with newly installed Eclipse.The project is not showing any error But when I run the project it force closes with NoClassDefFoundError at each point where I use Commonslang lib.

I dont know how to fix this problem.Please help?

Solution

  • I think there are "lib" folder in your project directory so just change it "libs" instead of "lib" and clean project and check it..
