Hey all,

Mentaer (Stefan) suggested I send a message to the JPP list to let
everyone know about a new OpenJump database plugin. I know there are
several other DB plugins out there, but they all seem to be
table-based.  I needed something that would let me put in arbitrary
spatial queries and display the results in Jump, so I wrote this
plugin.

Features:

* You can call stored procedures, query views, do inline calculations,
use DUAL in oracle,
  etc., and view the results in OpenJUMP
* Oracle Spatial support via GeoTools
* MySQL support via GeoTools
* Ability to save DB connection parameters for multiple DBs so you
don't have to keep
 retyping connection info every time you start jump or switch to a
different database.


Limitations:

* Read-only
* Handling of null geometries is kind of kludgy
* No postgres support, but that's on my todo list
* MySQL queries require "AsText" workaround to handle polygons
* Large result sets might cause out-of-memory errors in OpenJUMP.  A
resultset limit (similar to what the Squirrel JDBC client does) is
also on my todo list.

If you're interested, check out the plugin's main page at
http://jumpdbqplugin.sourceforge.net.   Let me know if you have
problems or suggestions.

Tested on Linux, using Oracle Spatial 10.x, and MySQL 4.1.11.
