Searching for a JDBC connector (free or commercial) with ERD

Hello,

do you know any java library (free or commercial) which permit to import data from databases whith JDBC, but also permit to import from "on the fly" views created in the import dialog ?

The most basic version would be a simple JTextField in which the user would enter some SELECT clause. But i need something more advanced, with ERD (Entity Relation Diagrams). Something like the request creator of Access.

There are a lot of tools to do that but they are standalone software wich is not good for our compagny. Do you know any library which meet those requirements?

Here is the list of the standalone software i've found:
- iSQL-Viewer : http://isql.sourceforge.net/index.html
- DbVisualizer : http://www.minq.se/products/dbvis/
- JDBC Manager : http://jdbcmanager.sourceforge.net/
- SQLeonardo : http://sqleonardo.altervista.org/
- dbWrench : http://www.dbwrench.com/
- AquaFold : http://www.aquafold.com/
- Happy Fish Database Designer : http://www.polderij.nl/happyfish/
- Toad Data Modeler : http://www.casestudio.com/enu/default.aspx
- ExecuteQuery : http://executequery.org/index.html
