[udig-devel] Server-sided udig

[Ugo Taddei <ugo.taddei@xxxxxxxxxxxxxxxxxx>]

Hello everyone,

this is so cool, I thought I'd share it with you.

We've managed to set up an environment in which udig runs as a server. 
Currently we're using it for map generation. That is, we take WMS 
requests and forward it to udig, which renders and delivers the map. In 
other words, we're written a uDig WMS without writing hardly any code at 
all! (In practice, our project has other requirements on the server - 
dynamic styles, dynamic layers - but that's already a good start.)

The whole stuff is running in Eclipse's OSGi container. We also use uDig 
as an authoring tool to "set up the WMS", that is, define the layers and 
their styles. From that on, the osgi bundle takes control, and delivers 
maps without you noticing it's not a "real" WMS. (Off course, not all 
operations are implemented and thus, it's not an OGC-conform WMS, at 
least not yet :-)

The only thing we changed in the code was a call in 
ProjectRegistryImpl.getProject(URI):

PlatformGIS.syncInDisplayThread(new Runnable() { ...

was substituted by a

  Runnable run = new Runnable() {
...

};
new Thread(run).start();

as there's no display and the method PlatformGIS.syncInDisplayThread(new 
Runnable) never returns (I think).

So far only tested on Windows XP, Eclipse 3.4.1, and the JRE from the 
udig site. Target platform will be Linux. If you want more details, 
please let me know.

Anyway, my compliments for your guys. (Really, we only wrote a mini 
servlet, all the code is yours!)

Cheers,

Ugo
