Hi all , i am using RedHat6.1 , jdk1.3 , postgresql7.0.1 and jBoss2.1 . The weird error are : I have deploy my ejb which included 3 entity and 1 session bean. The session bean is facade to the entity bean. When i run jboss container and called a method from session for example SearchByLikeProjectTitle() in my pc , it will display records in the database. All the method is execute ok in my PC . However when i try to execute the method in different PC , it did not display correct records. All the method is not execute correctly.If i call ejbcreate , it did not display my any error , but the records is not display in the table. And when i tried to use findByPrimaryKey() to find records which exists in the database , it display ObjectNotFoundException error eventhough the records exists in the table. Anybody have any idea why i tried to run jboss in different PC , it give me different results ? Thanks. public ArrayList searchByLikeProjectTitle(String projectitle) throws RemoteException,FinderException{ ArrayList result = new ArrayList(); System.out.println("projectinfohome" + projectinfohome); Collection collection = projectinfohome.findByLikeProjectName(projectitle); System.out.println("size" + collection.size()); Iterator iterator = collection.iterator(); while(iterator.hasNext()){ ProjectInfo projectinfo = (ProjectInfo)javax.rmi.PortableRemoteObject.narrow( iterator.next(),ProjectInfo.class); ProjectInfoJB projectinfojb = projectinfo.getProjectInfoJB(); result.add(projectinfojb); } return result; } _______________________________________________ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
