[Tilesathome] Experimental Batik Support

Wed Nov 14 14:09:39 GMT 2007

Got batik rendering.
I had to install the right java package first,
but my repository server was directed to 
a dutch server, instead of the main server.
abd the dutch one did not contain java-6

Anyway, a new problem appeared :

rendering of a tile is finished really quik (1 second)
and creates 1 empty tile.
The maplint process seems to run longer, but creates
a lot of empty files. Not much better.

Any clue  ???

Regards,

Ing. Gert Gremmen

Hi Gert,

Sounds like a class path problem, or possibly a library version
compatibility problem. I run XP, I am guessing you are on linux.

I did a bit of google search and found this:

> I'va installed the libgcj6-dev package!!! And it works!!

Does that make sense?

Regards,
Brent.
