<DIV> </DIV>
<DIV><FONT face="Times New Roman" color=#000000 size=3>But in other attempts, the response was OK (a XML file with the server capabilities)</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Times New Roman" color=#000000 size=3>This request works too (using the German EPSG;31429):</FONT></DIV>

<DIV> </DIV>
<DIV><FONT face="Times New Roman" color=#000000 size=3>This request returns a blank image, which I think is caused by a bug in the WMS server:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Times New Roman" color=#000000 size=3><A href="http://www.gis.nrw.de/wms/DGM50?REQUEST=GetMap&SERVICE=WMS&VERSION=1.1.0&LAYERS=DGM50&SRS=EPSG:4326&BBOX=6,50.5,8.5,53&WIDTH=300&HEIGHT=300&FORMAT=image/png&STYLES=&TRANSPARENT=TRUE">http://www.gis.nrw.de/wms/DGM50?REQUEST=GetMap&SERVICE=WMS&VERSION=1.1.0&LAYERS=DGM50&SRS=EPSG:4326&BBOX=6,50.5,8.5,53&WIDTH=300&HEIGHT=300&FORMAT=image/png&STYLES=&TRANSPARENT=TRUE</A></FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Times New Roman" color=#000000 size=3>The coordinates of the requested box are BBOX=6,50.5,8.5,53 which I think are correct and that should return an overview of that German state. Here is an example using the same coordinates with a different WMS server:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Times New Roman" color=#000000 size=3><A href="http://osmwms.itc-halle.de/maps/osmfree?SERVICE=WMS&&REQUEST=GetMap&SERVICE=WMS&VERSION=1.1.1&LAYERS=grenzen&SRS=EPSG:4326&BBOX=6,50.5,8.5,53&WIDTH=752&HEIGHT=499&FORMAT=image/jpeg&STYLES=default&TRANSPARENT=TRUE">http://osmwms.itc-halle.de/maps/osmfree?SERVICE=WMS&&REQUEST=GetMap&SERVICE=WMS&VERSION=1.1.1&LAYERS=grenzen&SRS=EPSG:4326&BBOX=6,50.5,8.5,53&WIDTH=752&HEIGHT=499&FORMAT=image/jpeg&STYLES=default&TRANSPARENT=TRUE</A></FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Times New Roman" color=#000000 size=3>So I think that WMS server says that it can provide maps in EPSG:4326, but it cannot, so you'll have to use EPSG;31429. Unfortunately, gvSIG Mobile 0.3 is unaware of that projection, so the GPS arrow will not be placed correctly. Distance and area measurements will work correctly as long as you choose a projection whose map unit is the meter (for example the Italian EPSG:3003)</FONT></DIV>
<DIV> </DIV>
<DIV>I have tested that WMS server from the gvSIG Mobile 0.3 workspace in Eclipse and it worked fine choosing EPSG:31429. Have you tried that option? </DIV>
<DIV> </DIV>
<DIV>As for the log file, yes you are right, that problem should be more visible in the log file, that's our fault.</DIV>
<DIV> </DIV>
<DIV>Go to Launcher.java and replace this line:</DIV>
<DIV> </DIV>
<DIV>Logger.getRootLogger().setLevel(Level.WARN);</DIV>
<DIV> </DIV>
<DIV>with:</DIV>
<DIV> </DIV>
<DIV>Logger.getRootLogger().setLevel(Level.ALL);</DIV>
<DIV> </DIV>
<DIV>Perhaps that'll show more messages.</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>Regards,</DIV></DIV>

<P><FONT size=2> Dear list,<BR><BR>anybody out there who has tried to load a WMS with the source code<BR>running in Eclipse?<BR><BR>I've tested the downloadable WinXP version -> no problems apart from the<BR>language which seems to be spanish only. However, that doesn't matter,<BR>but I don't understand why my self-compiled version does not load any<BR>WMS image. Is it possible that the SVN version is not the current<BR>version? Or did I forget to include something?<BR><BR><BR>Best regards,<BR><BR>Marcel Schoolmeesters<BR>_______________________________________________<BR>Gvsig_internacional mailing list<BR>Gvsig_internacional@listserv.gva.es<BR><A href="http://listserv.gva.es/cgi-bin/mailman/listinfo/gvsig_internacional">http://listserv.gva.es/cgi-bin/mailman/listinfo/gvsig_internacional</A><BR></FONT></P></DIV></BODY></HTML>
