    hi all

    i have used the below code  in my Compiere Application for printing IReport.

    Its working fine for first 4 or 5 prints , but after that , if i click Print Button ....my   application  goes into hange state and  Database Connection get Lost  resulting in throwing @NoDBConnection@ exception .

    i tried relpacing my Database to Oracle 10 G  from Oracle Xe  edition , but Stil the same  problem persists .

    this problem only coming in case of jasper ireport Prnting , other wise Application is running fine with perfect Database Conncetivity .

    Please Suggest the possible way out to this problem ?

    is Something went wrong in my code ? or some other problem ?

    With Regards

    Himanshu Walia
