All Implemented Interfaces:

public class NcxSoapRpcClientServlet

extends javax.servlet.http.HttpServlet

Servlet that acts as a client for SOAP-RPC calls to a netcdf to xml conversion service. The servlet must be invoked (via HTTP GET or POST) with the following request parameters:

• in = URL of netcdf file to be processed
• service = URL of SOAP rpcrouter to be invoked (which will invoke the "ncx" method of the service deployed with id "urn:ncx-rpc")
• format = optional flag for displaying in the browser plain XML (default) or HTML (obtained through conversion with the netcdf.xsl stylesheet)

The servlet must be deployed to the server with an initialization parameter that specifies the location of the style sheet used in the xml to html transformation. In other words, the web deployment descriptor for the servlet application must contain a piece of the form:

 <servlet>
  <servlet-name>NcxSoapRpcClientServlet</servlet-name>
  <display-name>netcdf to xml SOAP RPC client servlet</display-name>
  <servlet-class>ucar.ncx.soap.NcxSoapRpcClientServlet</servlet-class>
  <init-param>
     <param-name>xsl</param-name>
     <param-value>/usr/local/catalina/webapps/xslt/WEB-INF/netcdf.xsl</param-value>
  </init-param>
 </servlet>
