Mapviewer and WMS

Question

Hi,
I am trying to make the WMS servlet filter work, without success. I got my own datasource with styles/themes etc, and I am able to genereate previews using mapclient.jsp. GetCapabilities seems correct to me:
<Layer>
<Name>WMS</Name>
<Title>Oracle WebMapServer-lag etter datakilde.</Title>
<SRS>SDO:8307</SRS>
<LatLonBoundingBox minx="-180.0" miny="-90.0" maxx="180.0" maxy="90.0"/>
<Layer>
<Name>GMIVA_SDO</Name>
<Title>Datasource GMIVA_SDO</Title>
<Layer>
<Name>VALINES</Name>
<Title>Basemap VALINES</Title>
<SRS>SDO:0</SRS>
<LatLonBoundingBox minx="-180.0" miny="-90.0" maxx="180.0" maxy="90.0"/>
</Layer>
</Layer>
</Layer>
When making a GetMap request, I get the following exception (Norwegian is translated in bold):
<ServiceExceptionReport version="1.1.1">

What am I doing wrong here ? Any suggestion is welcome !

With MapViewer 11g EA1 (early access release 1), you can supply a custom SDO-EPSG srid map file; when present, this file tells MapViewer to automatically convert between equivalent SDO and EPSG srids. This is set in the mapViewerConfig.xml file, for instance:
<wms_config host="www.my_corp.com" port="80">
    <title>
        WMS 1.1 interface for Oracle Application Server 10g MapViewer
    </title>
    <abstract>
        This WMS service is provided through Oracle MapViewer.
    </abstract>
    <keyword_list>
       <keyword>bird</keyword>
       <keyword>roadrunner</keyword>
       <keyword>ambush</keyword>
    </keyword_list>
    <sdo_epsg_mapfile>
      ../config/epsg_srids.properties
    </sdo_epsg_mapfile>
  </wms_config>the format of the file (which must have .properties as file extension) is very simple. Each line contains one map from a SDO srid to an EPSG srid:
<sdo_srid>=<epsg_srid>
for instance a simple file may contain:
   81922=20248
   8307=4326
  ...Once you restart MapViewer it should recognize incoing wms req with EPSG srid, and also use EPSG srids when generating the capabilities response.
on a somewhat related note, if you havn't tried the MapViewer 11g EA1, it has a great feature called Oracle Maps, which gives your map a Google-maps look and feel. This Oracle Maps can be hooked up with any existing WMS services, and essentially turns any WMS served map layer into high-performant draggable web map.
