The line of code

    resCtx =3D new SOAPContext(); // get rid of old one

from RPCRouterServlet, only runs when an exception is thrown.

The code that runs is something like this

RPCRouterServlet:

        provider.locate( dd, callEnv, call, call.getMethodName(), =
fullTargetID,=20
                         reqCtx );
        ServerUtils.setResponseGzip(dd, reqCtx, resCtx);

ServerUtils:

        if (Boolean.TRUE.equals(reqCtx.getAcceptGzip())) {
          // Request specified gzip OK
          Hashtable props =3D dd.getProps();
          String gzip =3D props !=3D null ? (String) props.get("gzip") : =
null;
          resCtx.setGzip(gzip !=3D null && =
SoapEncUtils.decodeBooleanValue(gzip));
        } else if (Boolean.FALSE.equals(reqCtx.getAcceptGzip())) {
          // Request specified gzip not OK
          resCtx.setGzip(false);
        } else {
          // Request specified nothing, for now do not gzip
          // TODO: should accept be required?
          resCtx.setGzip(false);
        }

RPCRouterServlet:

        provider.invoke( reqCtx, resCtx );

RPCJavaProvider:

        Response resp =3D RPCRouter.invoke( dd, call, targetObject,=20
                                          reqContext, resContext );

RPCRouter:

    return new Response (call.getTargetObjectURI (), call.getMethodName =
(),
                         ret, null, null, respEncStyle, resCtx);

RPCJavaProvider:

        Envelope env =3D resp.buildEnvelope();
        StringWriter  sw =3D new StringWriter(1024);
        env.marshall( sw, call.getSOAPMappingRegistry(), resContext );
        resContext.setRootPart( sw.toString(), =
Constants.HEADERVAL_CONTENT_TYPE_UTF8);

RPCRouterServlet:

      // Generate response.
      TransportMessage sres =3D new TransportMessage(null, resCtx, null =
);
      sres.editOutgoing(editor);

      // Generate response byte array.
      sres.save();

TransportMessage:

        if (Boolean.TRUE.equals(ctx.getGzip())) {
            // Deflate
            ByteArrayOutputStream baos =3D
                               new ByteArrayOutputStream(bytes.length);
            GZIPOutputStream gzos =3D new GZIPOutputStream(baos);
            gzos.write(bytes, offset, bytes.length - offset);
            gzos.close();
            baos.close();
            bytes =3D baos.toByteArray();
            offset =3D 0;

            headers.put(Constants.HEADER_CONTENT_ENCODING, =
Constants.HEADERVAL_CONTENT_ENCODING);
        }

RPCRouterServlet:

      // Write.
      res.setStatus(status);
      res.setContentType(sres.getContentType());
      for (Enumeration headers =3D sres.getHeaderNames();
           headers.hasMoreElements(); ) {
          String name =3D (String)headers.nextElement();
          res.setHeader(name, sres.getHeader(name));
      }

      res.setContentLength(sres.getContentLength());
      OutputStream outStream =3D res.getOutputStream();
      sres.writeTo(outStream);

In order to have your service gzip the result, the client must specify =
that it accepts gzip, and the deployment descriptor must have the option =
set to allow gzip.  Remember that when you change the deployment =
descriptor, you must re-deploy the service.
