yep both ActionFormBeans are java bean compliant here's the code
note i didn't copy any irelevevant method (dont have reset() method for any
bean)
=============================
bean1
==============================
package beans.studyProgram;

private String description;
public StudyProgram() {
super();
}
public StudyProgram (Integer id) {
