I having problem to create entities from tables. The problem is I can create for some of them, but around 10% of tables can't be created automatically (Via Eclipse) or manually. Here is the details:
Mac Pro with i7 processor, with java 1.6 & Eclipse Helios installed.
Connector: sqljdbc4.jar, EclipseLink: 2.1.1
SQL 2005 server on remote machine in same network.

The error message:
Column "xxx" can't be resolved on table "xxxxxxxxxxxxx", even Data Source Explorer can't see the columns. But query via Sql Scrapbook(Eclipse build-in) is fine.
That table have around 25 columns, with around 200 records in that.

Please help..

Any idea?

Since Class Diagram are technique independed, so it will never include any technique related classes, but I'm confuse whether it's necessary to put action classes in it, like doSomething class (it's not noun classes).

Welcome any advice.
