At http://www.reumann.net/struts/ibatisLesson1/step6.do
this is an example in a ibatis/struts tutorial
public int update(String statementName, Object parameterObject) throws
DaoException {
int result = 0;
try {
sqlMap.startTransaction();
result = sqlMap.executeUpdate(statementName, parameterObject);
sqlMap.commitTransaction();
} catch (SQLException e) {
try {
sqlMap.rollbackTransaction();
} catch (SQLException ex) {
throw new DaoException(ex.fillInStackTrace());
}
throw new DaoException(e.fillInStackTrace());
}
return result;
}
Is it necessary to have a transaction started for just 1 statement
execution?
Also, what's the better way? Doing a transaction in a Service class, that
has multiple DAO's, or doing it in the DAO class, doing different statements
in one method? Or is there no difference?
