Java Question Error when Calling FirstLib Library.

[Azman]

I follow the instruction on youtube on how to create a library for B4A. I did successfully generate the FirstLib.jar and FirstLib.xml. I wrote a test application which call the library,however i got error
java.lang.NoClassDefFoundError: anywheresoftware.b4a.sample.FirstLib when i run the program.
Is there something wrong with my library? Or what did i do wrong?

I am using ADT with jre1.7 to compile

Attached is the source code for the FirstLib and textLibCall
