Find the modified attributes

   protected void doDML(int i, TransactionEvent transactionEvent) {
        byte state = this.getEntityState();
        if (state == this.STATUS_MODIFIED) {
            System.out.println(this.getEmployeeId().toString() +
                               " Has been Modified ");
            //Object[] modifiedAttributes =this.getAttributeNames();
            if (this.isAttributeChanged("FirstName")) {
                System.out.println(" FirstName Modified");
            }
            if (this.isAttributeChanged("LastName")) {
                System.out.println(" FirstName Modified");
            }


        }
        super.doDML(i, transactionEvent);

Try these solutions:  make sure that you check "refresh after insert" and refresh after update" for the primary key column in you entity object. in the application module tab Click the Properties tab and select jbo.locking.mode. Double click the “pessimistic”value next to the property to open the field editor and type “optimistic” over the value.Press enter. if error still exist then you must set "refresh after insert" and refresh after update" as true for all attributes in the entity object another way is to execute the View Object after the commit operation to bring back updated data to ViewObject. For this we need to override the  afterCommit()  of ViewObject class as follows:                  public void afterCommit(TransactionEvent){                         executeQuery();                       }              5- another way to solve this error is to overide the lock() method of the EntityImpl class       public void lock() {

Working With File Throgh WebUtill

These Functions Or APIs are: Copy_File :  Copies a file Returns a Boolean to indicate success.  Syntax :   Webutil_File.Copy_File(SourceFileName in Varchar2 , Destination In Varchar2) Return Boolean  Example   Declare  vCopied Boolean;  Begin   vCopied :=  Webutil_File.Copy_File('C:\temp\mypic.jpg','X:\destination_folder');  If vCopied = true Then    Message('File copied Successfully');  Else   Message('Error in Copying File');  End if; Delete_File:
