Lack of interest?So then people would rather have to implement their own tile
reading ( which i am sure they do..everybody around here uses a OSM or gmaps
right? ).
"The
story is, query the tiles for a BBOX, grab them into a
List<GridCoverage> and draw as normal."
Lost me here.. more details are invaluable. I see in the image tutorial
http://docs.geotools.org/latest/userguide/tutorial/raster/image.html that the
wms link has a bbox parameter. Could't that be used to fetch the image( at this
point i would also settle for a full image each time i pan instead of tiling)
from a wms server that acts as an adapter/translator between the application
and the tms? Please give more details regarding the bbox method. I hope i was
clear on what i want to do. Render an osm or googlemaps (or bing for that
matter) layer as background map for my features. Just like on the internet.
Only on the desktop :)

JMapPane are an example of how to use the GeoTools rendering engine in
Swing. Thus far nobody has contributed digitisation tools (although I
have seen a fair number of teams do this on their own - perhaps search
github?)" Can't find anything on github or google on this matter. But if
anything comes out of this i will gladly contribute. But i think i will need
someone to mentor me over this weekend because i need to do it this weekend.

Quickly:
- Sort of does CRUD already - feature = object, featuretype=class :D
- There is tile reading code in uDig, it was back ported once to geoTools but
due to lack of interest was eventually dropped. (I had one bug that stumped me
and pulled it rather than continue to answer questions). The story is, query
the tiles for a BBOX, grab them into a List<GridCoverage> and draw as normal.
- JMapPane are an example of how to use the GeoTools rendering engine in Swing.
Thus far nobody has contributed digitisation tools (although I have seen a fair
number of teams do this on their own - perhaps search github?)
- using hibernate is fine but perhaps not worth it? (it amounts to jdbc ->
object -> feature -> shape -> screen). I saw one team do it properly, using the
hibernate staging area directly and materialising features (rather than force
data into java POJOS).

running. I think i saw a post somewhere that this is not available.
If so, are there any workarounds?...like serving tms as wms or
something?

jMapPane and jMapFrame are the only ones i understand) support the

polygon on the mappanel and the use that polygon to query the db for
features inside that polygon?I'm thinking maybe i could
programatically create a layer to hold the polygon ( or polygons)
and when the user clicks a button i create a query, retrieve the
result and modify the style of those features that are in the result
set ( or actually i could just apply my custom made "feature
selected" style)
