Hi Jeff,
If there's a problem loading the specified projection, Mercator gets
loaded. Make sure the ProjectionFactoryLoader for the LLXY projection
is getting added in the ProjectionFactory properties. It probably is
if you started with the default openmap.propertes file, i.e.:
projFactoryLoader.class=com.bbn.openmap.proj.ProjectionFactoryLoader
projFactoryLoader.projectionLoaders=mercatorloader cadrgloader
ortholoader llxyloader gnomonicloader
projFactoryLoader
.mercatorloader.class=com.bbn.openmap.proj.MercatorLoader
projFactoryLoader.cadrgloader.class=com.bbn.openmap.proj.CADRGLoader
projFactoryLoader
.ortholoader.class=com.bbn.openmap.proj.OrthographicLoader
projFactoryLoader.llxyloader.class=com.bbn.openmap.proj.LLXYLoader
projFactoryLoader
.gnomonicloader.class=com.bbn.openmap.proj.GnomonicLoader
Also, if you cut-and-pasted the property below from your properties
file, Projection is misspelled, which would also cause this problem.
If the LLXY projection is set on the map, the image from the WMS
should line up for a EPSG 4326 request.
Hope this helps,
- Don
