[Montag-users] how to access montag services from a java client

[Alexandra M. <al...@ya...>]

Hello, 

I am new to webservices and montag, and despite my efforts
reading soap and wsdl tutorials, I am not able to interact
successfully with Montag :(
I coded up a simple java client program to access one of
the montag methods (e.g., createCollection), but I keep
getting this error:

    Error encountered:
    montag.core.MontagSOAPFault

Here is the source code of the java program I wrote, in
case it helps. 

=================================================================
package montagTest;

import java.net.URL;
import java.util.Vector;
import java.util.Iterator;
import org.apache.soap.Constants;
import org.apache.soap.Fault;
import org.apache.soap.SOAPException;
import org.apache.soap.rpc.Call;
import org.apache.soap.rpc.Parameter;
import org.apache.soap.rpc.Response;

public class CollectionAdder {

	static final String MONTAG_URL =
"http://localhost:8080/montag/services/CollectionManager/";

    public void add(URL url, String parent, String newCol)
        throws SOAPException {

        System.out.println("Adding collection '" + newCol +
"' to '" +
            parent + "'");

        // Build the Call object
        Call call = new Call(  );
        call.setTargetObjectURI("CollectionManager");
        call.setMethodName("createCollection");
       
call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);

        // Set up parameters
        Vector params = new Vector(  );
        params.addElement(new Parameter("parent",
String.class, parent, null));
        params.addElement(new Parameter("newCol",
String.class, newCol, null));
        call.setParams(params);

        // Invoke the call
        Response response;
        response = call.invoke(url, "");

        if (!response.generatedFault(  )) {
            System.out.println("Successful collection
addition.");
        } else {
            Fault fault = response.getFault(  );
            System.out.println("Error encountered: " +
fault.getFaultString(  ));

            Vector entries = fault.getDetailEntries(  );
			for (Iterator i = entries.iterator(); i.hasNext(  ); ) {
				org.w3c.dom.Element entry =
(org.w3c.dom.Element)i.next(  );
			   
System.out.println(entry.getFirstChild().getNodeValue(  ));
		    }
        }
    }

    public static void main(String[] args) {
        if (args.length != 2) {
            System.out.println("Usage: java
javaxml2.CollectionAdder [Parent Collection] " +
                "[New Collection]");
            return;
        }

        try {
            // URL for SOAP server to connect to
            URL url = new URL(MONTAG_URL);

            // Get values for new collection
            String parent = args[0];
            String newCol = args[1];

            // Add the collection
            CollectionAdder adder = new CollectionAdder( 
);
            adder.add(url, parent, newCol);
        } catch (Exception e) {
            e.printStackTrace(  );
        }
    }
}
=================================================================

Any help or advice is greatly appreciated.
Thanks,

Alexandra
