soap questions

[Bert Coessens <Be...@esat.kuleuven.ac.be>]

Dear all,

I have two questions:

* does anybody know a convenient way to get the list of deployed 
services on a remote server whitout having to use the 
ServiceManagerClient (which is a little dangerous letting to use by 
clients). I wrote a client (see below) able to do this, and it works, 
but I don't know if this is the correct way to do. Does anybody have an 
alternative?

* is there a way to extract the arguments/parameters a service needs 
before sending a request (with possibly wrong parameter settings) or do 
I just have to try and catch if things didn't work?

Thanks a lot,
Bert

public class ServiceLister
{
  public String[] list (String url) throws Exception
  {
    Call call = new Call ();

    call.setTargetObjectURI (ServerConstants.SERVICE_MANAGER_SERVICE_NAME);
    call.setMethodName ("list");
    call.setEncodingStyleURI (Constants.NS_URI_SOAP_ENC);

    Response resp = call.invoke (new URL(url), "");

    if (!resp.generatedFault ())
    {
      Parameter result = resp.getReturnValue();
      String[] services = (String[]) result.getValue();
      return services;
    }
    else
    {
      return null;
    }
  }
}

I think I can help you on the first question...

--- You could of course use the ServiceManager class's list() method which
is likely what the ServiceManagerClient uses...
