Hi everyone,
I would like to ask if anyone has used the Java JXMapViewer class developed by swing labs with geoserver. I was told it is a Map viewer and it has support for fetching maps from a wms server and map viewing capabilities. What are your experiences ?
Thanks,
Roman

I don't know anyone of us who tried to use JXMapViewer. I'm just
answering so that you don't feel totally ignored, sorry I don't have
any experience to share 
Cheers

It seems to work out of the box, all I did was add these two lines to
JXMapKit (lines 623)
WMSService wms = new
WMSService("http://localhost:8080/geoserver/wms?","topp:states"\);
tf = new WMSTileFactory(wms );
and it all worked, obviously for best results you'll want to look into
using a tiled cache such as GeoTileCache.

Hi,
Thanks for your mail, tried what you said but the topp:states map does not
display in JXMapViewer. When i look at the tomcat console, geoserver
displays the wms request sent by JXMapViewer as
"
http://localhost:8080/geoserver/wms?version=1.1.1&request=GetMap&layers=topp:states&format=image/jpeg&BBOX=-0.002,-0.002,0.0,0.0&width=500&height=500&SRS=EPSG:4326&Styles=
"
I believe the problems lies with the BBOX parameter that JXMapViewer class
generates (i don't know why it specifies BBOX = -0.002, -0.002, 0.0, 0.0 as
the bounding box values to be used in the wms query. Even on a web browser
this query will not retrun any result because the bounds are wrong. I used
exactly the same code as you specified.
Try zooming out in the viewer, your zoomed into where the equator
crosses the Greenwich meridian so there are no US States to see. So
zoom out and pan left to see some map.
Any ideas as regards this strange problem ? and by the way what is
GeoTileCache ?
Its a piece of software that sits between geoserver and tiled clients
(like JXMapViewer) and saves (or caches) the tiles as they are
requested to speed up subsequent requests and to save load on the
server which other wise has to draw each tile each time. See
http://geowebcache.org/trac and
http://blog.geoserver.org/2007/02/26/tilecache-tutorial/ for more
details

When i run the program the map is already zoomed out i.e. at the first zoom
level. But isn't JXMapViewer supposed to determine the appropriate bounds
for the topp:states map (automatically) and specify it in the wms request ?
or is there a method to set the bounds of each wms request JXMapViewer makes
?
To me it will be a stressful exercise to zoom to the appropriate map bounds
each time JXMapViewer makes a wms request
JXMapViewer doesn't know or care about what is being displayed, the
key lines you'll need to change are
kit.setZoom(14);
kit.setAddressLocation(new GeoPosition(51.5,0));
which seem to set the zoom level and the centre of the map (Some where
near London UK in this case).
