[Geoserver-users] RE: Adding the SLD body dynamically

GeoServer GeoServer User

Hi,

I want to add the SLD body of the map dynamically rather than statically
through the context.xml file. That is, I want to display not all, but only
some of the features, of a map layer depending on the input from the user.
Can anyone be kind enough to give advice on how this can be done in
GeoServer ands MapBuilder?

Hope I am clear in my question. Thanks.

You should be able to do something like that using SLD-POST. There is some information on SLDs here: http://docs.codehaus.org/display/GEOSDOC/SLD%20Explanations%20and%20Samples
It is a good starting point.

Hi Brent,

Thank you for your reply. Pardon me, but the SLD-POST link under the URL you
have given to me does not contain any information. Could you please point
out to me where I can get relevant information to help in the implementation
of my desired feature as described? Thank you.

Hi Lee Wai See,

  I have recently been working with this as well. Alex Petkov has a
nice example: http://docs.codehaus.org/display/GEOSDOC/SLD+Snippets

Look at the bottom. If you take out the first named layer it will work
directly with the geoserver1.3.war demo/sampleRequest/ using the TestWfsPost

Also add the topp: prefix to states => topp:states

url:
http://localhost:8080/geoserver/wms/GetNap

body:
<?xml version="1.0" encoding="UTF-8"?>
<ogc:GetMap
xmlns:ogc="http://www.opengis.net/ows&quot;
xmlns:gml="http://www.opengis.net/gml&quot;
version="1.1.1" service="WMS">
  <StyledLayerDescriptor version="1.0.0">
   <NamedLayer>
    <Name>topp:states</Name>
     <NamedStyle>
      <Name>population</Name>
     </NamedStyle>
    </NamedLayer>
   </StyledLayerDescriptor>
   <BoundingBox srsName="http://www.opengis.net/gml/srs/epsg.xml#4326&quot;&gt;
    <gml:coord>
     <gml:X>-130.0</gml:X>
     <gml:Y>24.0</gml:Y>
    </gml:coord>
    <gml:coord>
     <gml:X>-66.0</gml:X>
     <gml:Y>50.0</gml:Y>
    </gml:coord>
   </BoundingBox>
   <Output><Format>image/png</Format>
    <Size>
     <Width>600</Width>
     <Height>320</Height>
    </Size>
   </Output>
   <Exceptions>application/vnd.ogc.se+xml</Exceptions>
  </ogc:GetMap>

I don't know the way mapbuilder works but here is a sample code for using
java to feed a custom sld to a wms/GetMap Post

Snippet:
try {
  URL u = new URL("http://www.web-demographics.com/geoserver/wms/GetMap&quot;\);
  HttpURLConnection geocon = (HttpURLConnection)u.openConnection();
  geocon.setAllowUserInteraction(false);
  geocon.setRequestMethod("POST");
  geocon.setRequestProperty("Content-Type", "application/xml");
  geocon.setDoOutput(true);
  geocon.setDoInput(true);
  geocon.setUseCaches(false);
  System.out.println("GetImage\n"+sld.toString());
  xmlOut = new PrintWriter(new BufferedWriter(new
           OutputStreamWriter(geocon.getOutputStream())));
  xmlOut.write(sld.toString());
  xmlOut.flush();
  xmlOut.close();
  response.setHeader("Cache-Control", "no-store, no-cache,
                      must-revalidate");
  response.addHeader("Cache-Control", "post-check=0, pre-check=0");
  response.setHeader("Pragma", "no-cache");
  response.setContentType("image/jpeg");
  OutputStream outsld = response.getOutputStream();
  int c;
  InputStream in = geocon.getInputStream();
  while ((c = in.read()) != -1) outsld.write(c);
  in.close();
  outsld.close();
            
} catch (IOException e) {
  e.printStackTrace();
} catch (Exception e) {
  System.out.println("WMSFeature: "+e.toString());
}

Here is another example sld for filtering by bounding box and parameter
value:

Hey Randy, could you edit Alex's example to use topp:states? And put your other examples up on that page as well? You just need to sign up for a wiki account, see http://docs.codehaus.org/display/GEOSDOC/Guide+to+Documenting+GeoServer for more information and documenting advice. It would be great to post the code snipped on the wiki, and we made the SLD Snippets so a number of different users could all put up sample SLDs...

best regards,

Chris

Hello Randy:

Thank you very much for the samples. Can you explain where sld was
declared below (in the java code)? Maybe I just missed it.

Also, please feel free to post any SLD examples (like the you posted
on the bottom) to the wiki page. I won't mind doing that myself,
except that you probably know best what that particular SLD will
accomplish. Also, it looks like it's making a picture, so (with a risk
of portraying myself as a pest) can I ask you to post it to the
Gallery? If you want, attach a static image to an email and I will
post it.

http://docs.codehaus.org/display/GEOSDOC/Gallery

Cheers,

Alex

try {
URL u = new URL("http://www.web-demographics.com/geoserver/wms/GetMap&quot;\);
HttpURLConnection geocon = (HttpURLConnection)u.openConnection();
geocon.setAllowUserInteraction(false);
geocon.setRequestMethod("POST");
geocon.setRequestProperty("Content-Type", "application/xml");
geocon.setDoOutput(true);
geocon.setDoInput(true);
geocon.setUseCaches(false);
System.out.println("GetImage\n"+sld.toString());
xmlOut = new PrintWriter(new BufferedWriter(new
          OutputStreamWriter(geocon.getOutputStream())));
xmlOut.write(sld.toString());

You should be able to do something like that using SLD-POST. There is
some information on SLDs here:
http://docs.codehaus.org/display/GEOSDOC/SLD%20Explanations%20and%20Samples
It is a good starting point.

Aaahh you beat me to it Chris.

Hey Randy, could you edit Alex's example to use topp:states? And put
your other examples up on that page as well? You just need to sign up
for a wiki account, see
http://docs.codehaus.org/display/GEOSDOC/Guide+to+Documenting+GeoServer
for more information and documenting advice. It would be great to post
the code snipped on the wiki, and we made the SLD Snippets so a number
of different users could all put up sample SLDs...

I just saw that the example in question is specific to the WCS branch,
so maybe the raster layer should be taken out.

Hi Randy George,

Thanks for the information given. They should be useful for me. However, I
still have some doubts, which I hope you can clear them for me:

1. With respect to the java code snippet to feed a custom SLD to a
wms/GetMap post, after getting back the response as an image file, how do
i display this image on my jsp page?

2. Again, with respect to the java code snippet, what is the sld declared?

Thank you.

Regards,
Lee Wai See

Hi Lee Wai See,

  I have recently been working with this as well. Alex Petkov has a
nice example: http://docs.codehaus.org/display/GEOSDOC/SLD+Snippets

Look at the bottom. If you take out the first named layer it will work
directly with the geoserver1.3.war demo/sampleRequest/ using the
TestWfsPost

Also add the topp: prefix to states => topp:states

url:
http://localhost:8080/geoserver/wms/GetNap

   <Exceptions>application/vnd.ogc.se+xml</Exceptions>

I don't know the way mapbuilder works but here is a sample code for using
java to feed a custom sld to a wms/GetMap Post

Snippet:
try {
  URL u = new URL("http://www.web-demographics.com/geoserver/wms/GetMap&quot;\);
  HttpURLConnection geocon = (HttpURLConnection)u.openConnection();
  geocon.setAllowUserInteraction(false);
  geocon.setRequestMethod("POST");
  geocon.setRequestProperty("Content-Type", "application/xml");
  geocon.setDoOutput(true);
  geocon.setDoInput(true);
  geocon.setUseCaches(false);
  System.out.println("GetImage\n"+sld.toString());
  xmlOut = new PrintWriter(new BufferedWriter(new
           OutputStreamWriter(geocon.getOutputStream())));
  xmlOut.write(sld.toString());
  xmlOut.flush();
  xmlOut.close();
  response.setHeader("Cache-Control", "no-store, no-cache,
                      must-revalidate");
  response.addHeader("Cache-Control", "post-check=0, pre-check=0");
  response.setHeader("Pragma", "no-cache");
  response.setContentType("image/jpeg");
  OutputStream outsld = response.getOutputStream();
  int c;
  InputStream in = geocon.getInputStream();
  while ((c = in.read()) != -1) outsld.write(c);
  in.close();
  outsld.close();

} catch (IOException e) {
  e.printStackTrace();
} catch (Exception e) {
