Thanks for the quick reply, I just learned java for a few weeks, still trying
to get use to eclipse, can you show me how to enable debug logging to see
the generate query?
here is my dbAccess method using generic:
public T getObjectById(String query, UUID id) {
T rObject = null;
// reset the error
this.error = "";
try {
rObject = (T)sqlMap.queryForObject(query, id);
} catch (SQLException e) {
// System.out.println(e);
this.error = e.getMessage();
}
return rObject;
}
and here is my testing code:
DBAccess<Person> ac = new DBAccess<Person>();
Person p = ac.getObjectById("getPersonById",
UUID.fromString("A26A19F6-18C4-4ba0-84BB-6EAD12B4CB8D"));
System.out.println(p.getId());
I have tested my DBAccess with a different object using the String type and
I got data back, so I don't think it's my DBAccess code is the problem.
