how to catch NonUniqueObjectException and throw a message back to user

[sburgula1]

Hi

I am getting a NonUniqueObjectException while I am trying to insert a row into a table.  As far as what is happening, it is happening correct.  But I would like to catch that exception and display a message back to the user.

I will paste a sample code, so that it gives a better idea of what I am trying to accomplish.

public String addPhdEdPlan() throws HibernateException{

try{
                                                               
    if(this.getAcademicYear() != null && this.getAcademicYear().length()>0){
        if(!isDuplicate()){
             Short academicYear = Short.valueOf(this.getAcademicYear());
             phdDataEdPlan.getId().setAcademicYear(academicYear);
        }
    }
}catch(NonUniqueObjectException ne){
                               
throw new NonUniqueObjectException("Duplicate academic Year being added for this Student's Education Plan", PhdDataEdPlanId.class, PhdDataEdPlanId.class.getCanonicalName());

/*facesMessages.add("Duplicate academic Year being added for this Student's Education Plan");*/
                                       
}

}


So when I try and add a duplicate record, it should display this message on the screen, when the exception occurs.

I hope I have conveyed my intention properly.

Please let me know if it needs clarification.

Hoping to hear soon.

thanks
Sai

you need to catch this exception NonUniqueObjectException inside your pages.xml
GO inside this pages.xml and see how other exceptions have been defined.

Thanks for the quick response.  But this exception is that of hibernate not of Seam.  Dont you define only Seam related exceptions in pages.xml.  This exception I am getting when I am adding a object into a table, and comparing the Academic year exists already in the table or not.
