You have to setup your project correctly. Actually, the HelloWorld project that comes in the zip of the latest version should work on newer Eclipse plugins as it is.... ??? Anyway...either place the jpct jar in libs (NOT lib) or edit your project's build path and add the jpct jar to the resources to be exported.

Hello All,

This is a common issue and this can be fixed by:

1. Copy the .jar file to the 'libs' folder.

2. Make sure that the .jar file is listed in the 'Java Build Path' 'Libraries' tab.

3. Make sure that the .jar file is checked in the 'Java Build Path' 'Order and Export' tab.

4. Take a clean build.

Thanks,
Binu Paul
