Generic GUI JDBC DB manager ?

[Mikey Warren]

This might be a stupid question - I only know the basics of SQL / JDBC.
Anyway I've been learning J2EE using Suns RI, and also JBoss which both come with databases (Cloudscape and Hypersonic) with, as far as I can tell no user interface - I was thinking wouldn't it be fairly easy to write a generic interface to let you view and create and edit tables that would work with any database with a JDBC connection.
If so is there one already available ?
If its not easy or not a sensible thing to do then why not ?( I realise its not an issue with commercial databases which come with there own manager software )
thanks Mike

Some excellent tools for oracle database are avaialable like TOAD..

It won't do absolutely everything, but DbVisualizer is a nice little tool. Try the free edition. Also many IDE's such as NetBeans have some elementary database access functionality built in or available as a free add-on.
