Hi, In my timer repeat I am getting data from hibernate query using spring hibernate class (hibernateDAO() which is written by me) in a beanshell script . It is working fine for some time. After a few minutes it give hibernate error "Row was updated or deleted by another transaction" . I thought even I just select few data from a database when any other used that table timer gets cancelled. My timer should repeat for every 30 seconds . Suggest me a better way of excuting hibernate in timer repeat. I have written my code as follows - <task-node name="Process Maintanence Request"> - System.out.println("############### i am in Process Maintanence Request ################"); - - import bsh.*; import com.expeditor.processors.HibernateDAO; h = new HibernateDAO(); h.executeQuery("from jbpm_processinstance"); System.out.println("******************** Timer *************************"+h+"query"+h.executeQuery("from jbpm_processinstance")); </task-node> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4101561#...
