Java Programming

im using JBuilder X and getting this error message:

package com.borland.jbcl.layout does not exist

considering that JBuilder has some problem i compiled the classes using command prompt but even then the same error appeared. plz help me its part of my final project of a courde.

Some ppl in diff forums have said that jbcl has been deprecated but making gui in JBuilder is much easier. and i only know of making frames in XYLayout,,,,,,,
If i dont have the package plz let me know how can i get it and if i have it then tell me how can it get it and where and how to install
