Hi,
 
Thanks for your help. I just tried it with the older version (without the proj4.jar) and now it works fine.
When I follow the configurationsteps on the WMS Demo for Windows, than there must be an error
 
    Windows:
    LD_LIBRARY_PATH=the/path/to/proj.dll
    PROJ_LIB=the/path/to/proj4-files (epsg,world)
 
 Doesīt matter. The RTB now works fine, but I donīt get back the image(saltlake). There is an error without description
   

<?xml version="1.0" encoding="UTF-8"?><ServiceExceptionReport xmlns="http://www.opengis.net/ogc"><ServiceException code="InvalidParameterValue" locator="-"/></ServiceExceptionReport>

I tried it at another PC with the same configuration, same Windows and same JDK,JRE and I get the image.

Whats the problem. Who have an idea?

Alex
