Title: RE: deploying services

That should have been "spec" not "space" in my previous posting :-)

It appears that the implementation of ServletContext.getRealPath() in WebLogic 5.1 always returns null when running out of a WAR (as is allowed by the space).  So the Apache SOAP code (in ServerHTTPUtils.getFileFromNameAndContext()) will then look for the file relative the current working directory of the server.

Thanks for the correction.  I did try putting soap.xml in my WAR and it didn't seem to find it.  It's entirely possible that I specified the path incorrectly.  I'll try a few more experiments and let you know.

Hi Brian and Rich,

 

A WebApp can read files from its own WAR. ServletContext has a getRealPath(String) method which can be used to resolve files relative to the servlet's docBase. We use this method to retrieve the configuration file, soap.xml. Since servers are not obligated to implement the getRealPath() method (they can return null if there is no absolute path to the resource) this only works if the server's impl of this method returns a non-null value. In that case, you need to specify an absolute path using the servlet init parameter.

 

Have you tried putting the soap.xml file in your war file? It should work fine.

 

Thanks,

-Matt

Isn't this it?

     <init-param>
         <param-name>ConfigFile</param-name>
         <param-value>soap.xml</param-value>
    </init-param>

which is set in your web.xml file for the RPCRouterServlet.

The entire entry I use is:

  <servlet>
    <servlet-name>soap</servlet-name>
    <display-name>Apache-SOAP RPC Router</display-name>
    <servlet-class>org.apache.soap.server.http.RPCRouterServlet</servlet-class>
    <init-param>
      <param-name>faultListener</param-name>
      <param-value>org.apache.soap.server.DOMFaultListener</param-value>
    </init-param>
    <init-param>
        <param-name>ConfigFile</param-name>
        <param-value>soap.xml</param-value>
   </init-param>
  </servlet>

To set soap server config file, it says you can specify a parameter that
the transport listener (i.e. RPCRouterServlet) passes along to the SOAP
server during startup.  Where do I set this parameter.  Anybody!  Thanks.
