Failure accessing WMS theme

Question

Hi to All,
I'm trying to call a WMS with mapviewer (OC4J 10g)to add a Layer to an existing map, so as i've seen from documentation i've added a new theme to my maprequest:
<theme name="WMS" >
<wms_getmap_request isBackgroundImage="false" >
<service_url>
http://web.rete.toscana.it/sgrwms/com.rt.wms.RTmap?
</service_url>
<version>
1.1.0
</version>
<format>
image/png
</format>
<srs>
EPSG:3003
</srs>
<bgcolor>
0xFFFFFF
</bgcolor>
<transparent>
true
</transparent>
<exceptions>
application/vnd.ogc.se_inimage
</exceptions>
<layers>
_idreg,idprov,idcomuni
</layers>
</wms_getmap_request>
</theme>
and i receive always a red message on my map witch say:
Failure accessing WMS theme,
am i missing something?
To access external URL I need a proxy where I have to set url, port, userid and password.I've seen in my mapviewer config file "mapViewerConfig.xml" a tag "web_proxy" but i cannot set userid and password, only url and port.
Could someone send me a real example of xml theme that works?
Please help me,
Thank U,
Francesco

Hi Francesco,
I have the proxy information set on MapViewer configuration file, and was able to get the map with the following request (note that I changed the SRS to EPSG:4326).
<?xml version="1.0" standalone="yes"?>
<map_request
             title="wms sample"
             datasource = "mvdemo"
             width="900"
             height="450"
             bgcolor="#a6cae0"
             antialiase="false"
             format="PNG_STREAM">
  <center size="2">
     <geoFeature  >
         <geometricProperty typeName="center">
             <Point>
                 <coordinates>11, 43</coordinates>
             </Point>
         </geometricProperty>
     </geoFeature>
  </center>
  <themes>
    <theme name="WMS" >
      <wms_getmap_request isBackgroundImage="false" >
      <service_url>
          http://web.rete.toscana.it/sgrwms/com.rt.wms.RTmap?
      </service_url>
      <version>
        1.1.0
      </version>
      <format>
       image/png
      </format>
     <srs>
      EPSG:4326
     </srs>
     <bgcolor>
        0xFFFFFF
     </bgcolor>
     <transparent>
       true
     </transparent>
     <exceptions>
        application/vnd.ogc.se_inimage
     </exceptions>
     <layers>
         _idreg,idprov,idcomuni
     </layers>
     </wms_getmap_request>
    </theme>
  </themes>
</map_request>Edit MapViewer configuration file, then uncomment and set the <web_proxy> parameters. Save and restart MapViewer, then add data source "mvdemo" and run the request.
