Error UPDATE_ROW_CONFLICT with Oracle DB

Question

Hi all,
I have a problem in UPDATE Operation with a Oracle DataBase, it works in Sun Application Server and not in Tomcat (5.5.12):
code:
try {
        RowKey[] selectedRowKeys = getTableRowGroup1().getSelectedRowKeys();
        for(int i=0; i< selectedRowKeys.length; i++){
            info("course selected"+courseinformationDataProvider.getValue("COURSECODE", selectedRowKeys));
Object course_code=courseinformationDataProvider.getValue("COURSECODE", selectedRowKeys[i]);
getSessionBean1().getCourseinformationRowSet1().setObject(1,course_code);
courseinformationDataProvider1.setValue("STATUS","T");
courseinformationDataProvider1.commitChanges();
courseinformationDataProvider1.refresh();
info("Row(s) Updated");
} catch (Exception e) {
log("Exception occurred!!", e);
error("Exception"+e);
It throws exception while i try to run in tomcat5.5.7
Exceptionjava.lang.RuntimeException: Number of conflicts while synchronizing: 1 SyncResolver.UPDATE_ROW_CONFLICT row 0 values changed in database
plz give some ideas..
Thanks in advance.....
