    Null Exception

    I have implemented a code for one form its name is hardware form and first i will enter data it will take it and after enetering the second time it is gving me an null pointer exception it is not allowing me to update this form please can any one help me out.
    Regards,
    rahul.

    Code where it is giving error is (in editing):


    public String add_action() {

    RequestBean1 bean = getRequestBean1 ();
    String name= this.getProject _id().getText() .toString();

    CachedRowSetDat aProvider pro_allocDataPr ovider = bean.getProject _allocateDataPr ovider();

    try {

    if(pro_allocDat aProvider.getRo wCount()>0) {

    pro_allocDataPr ovider.cursorFi rst();
    do {

    if (pro_allocDataP rovider.getValu e("project_allo cate.project_id ").toString().e quals(name)) {
    System.out.prin tln(name);
    pro_allocDataPr ovider.setValue ("project_alloc ate.project_id" , this.getProject _id().getText() );
    pro_allocDataPr ovider.setValue ("project_alloc ate.project_nam e", this.getName(). getText().toStr ing() );
    pro_allocDataPr ovider.setValue ("project_alloc ate.owner", this.getOwner() .getText().toSt ring() );

      1.) Use code tags when posting code.
      2.) The exception stacktrace should tell you the exact line number where the exception was thrown.

              You forgot those code tags again.
