Hello, I managed it to insert some data with JDO. Also i can update some variables with the following code (i postet just the relevant, executed parts of the code):
PersistenceManager pmUserSession = PMF.get().getPersistenceManager(); Transaction txUserSession = pmUserSession.currentTransaction(); txUserSession.begin(); String query = "select from " + JDOsess.class.getName(); Object responce = pmUserSession.newQuery(query).execute(); List<JDOsess> userSessions = (List<JDOsess>) responce; for(JDOsess session : userSessions){ if(...) ... session.setU_Times(newTime); } txUserSession.commit(); pmUserSession.close(); but when i want to change another variable (later, in an other function), the changes wont be saved. But there is no exception thrown :-( PersistenceManager pmUserSession = PMF.get().getPersistenceManager(); Transaction txUserSession = pmUserSession.currentTransaction(); txUserSession.begin(); session.setU_UserState(2); txUserSession.commit(); pmUserSession.close(); Any ideas why it works for the first time but don't work the second time? Do i have to reload the variable before the second change? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
