Solution 2:

Yes, this because of your .jar file didn't import properly. Follow below steps -

1. Place your .jar file in your project's libs folder.

2. Import it into your project. And, GoTo project -> properties -> Java build path -> order tab.

3. Check, whether your .jar file checked and placed in order of 1st. This is the main thing.

Hope these steps helps you. Have a look at below image -

Solution 3:

If you had put your jar files in lib folder change its name to libs. Then build path from that libs folder.
