problems with call.invoke()

[Edgar Castanedo <EC...@AHL.ORG>]

I am having trouble with call.invoke(). My test app is throwing a
SAXException:

- Exception:
org.xml.sax.SAXException: Bad types (int -> class java.lang.String)

org.xml.sax.SAXException: Bad types (int -> class java.lang.String)

Here is what my code looks like (I just started using axis, so any help
would be appreciated):

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;
import org.apache.axis.Constants;
import javax.xml.namespace.QName;
import javax.xml.rpc.ParameterMode;

public class TestXML extends HttpServlet {

        public void doPost(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {

                    try {

                        String userName = "";
                        String loanData = "";
                        String action = "EmpLogin";
                        String params = "";
                        Boolean compressResp = new Boolean("false");

                        String endpoint = "http://localhost/soap/test";

                        Service  service = new Service();
                        Call     call    = (Call) service.createCall();

                        call.setTargetEndpointAddress( new
java.net.URL(endpoint) );
                        call.setOperationName(new QName("http://localhost",
"SomeAction"));
                        call.setReturnType(Constants.XSD_STRING);

                        call.addParameter("UserName", Constants.XSD_STRING,
ParameterMode.IN);
                        call.addParameter("Data", Constants.XSD_STRING,
ParameterMode.IN);
                        call.addParameter("Action", Constants.XSD_STRING,
ParameterMode.IN);
                        call.addParameter("Params", Constants.XSD_STRING,
ParameterMode.IN);
                        call.addParameter("CompressResp",
Constants.XSD_BOOLEAN, ParameterMode.IN);

                        String ret = (String) call.invoke( new Object[] {
userName, data, action, params, compressResp } );

                        System.out.println("Sent 'Hello!', got '" + ret +
"'");

                    } catch (Exception e) {
                        System.err.println(e.toString());
                    }

        }

        public void doGet(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
                this.doPost(request,response);
        }
}

Thanks!
