Need Assistance With Apache SOAP Issue

[Neil Hainer]

Hi,
I am having a heck of a time getting the following APACHE SOAP V2.3 service to work. I was wondering if anyone had any constructive ideas?
The following code is the client .jsp file. The service uses session scope because I first want to call the class constructor and initialize the object. Then a second call is made to one of it's methods that requires no arguments:

<%@ page language="java" 
    import="java.net.*, java.util.*, org.apache.soap.*,org.apache.soap.rpc.*, org.apache.soap.transport.http.*"
%>
<%

URL url = new URL("http://127.0.0.1:8888/soap/servlet/rpcrouter");

Call call = new Call();
call.setTargetObjectURI("urn:SingleRateOfAdvanceService");

call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
//values required for the constructor
        //char _vehicleComposition[]
        String composition = new String( (char[])session.getAttribute("composition") );
        //char _operationalCondition[]
        String operationalCondition = new String( (char[])session.getAttribute("operationalCondition") );
        //char _roadClass[]
        String rtype = new String( (char [])session.getAttribute("rtype") );
        //char _roadWidth[]
        String surfaceWidth = new String( (char[])session.getAttribute("surfaceWidth") );
        //char _roadCondition[]
        String surfaceCondition = new String( (char[])session.getAttribute("surfaceCondition") );
        //char _roadGradient[]
        String gradFact = new String( (char[])session.getAttribute("gradFact") );
        //int _numberOfVehicles
        //int number_Of_Vehicles =  Integer.parseInt(session.getAttribute("number_of_vehicles").toString());
        Integer number_Of_Vehicles = new Integer(session.getAttribute("number_of_vehicles").toString());
        //int _numberOfSegments
//int segments = Integer.parseInt(session.getAttribute("segments").toString());
        Integer segments = new Integer(session.getAttribute("segments").toString());
        //int _lengthOfDay[]
        int lengthOfDay[] = (int[])session.getAttribute("lengthOfOpDay");
        //String lengthOfDay[] = (String[])session.getAttribute("lengthOfOpDay");
        //int _segmentLength[]
        int nodeLength[] = (int[])session.getAttribute("nodeLength");
        //String nodeLength[] = (String[])session.getAttribute("nodeLength");
        //int _vehicleDensity[]
        int vehicleDensity[] = (int[])session.getAttribute("vehicleDensity");
        //String vehicleDensity[] = (String[])session.getAttribute("vehicleDensity");
        //int _vehicleType[]
        int vtype[] = (int[])session.getAttribute("vtype");
        //String vtype[] = (String[])session.getAttribute("vtype");

Vector params = new Vector();
params.addElement(new Parameter("_numberOfVehicles", Integer.class, number_Of_Vehicles, null));
params.addElement(new Parameter("_numberOfSegments", Integer.class, segments, null));
params.addElement(new Parameter("_vehicleDensity", int[].class, vehicleDensity, null));
params.addElement(new Parameter("_vehicleType", int[].class, vtype, null));
params.addElement(new Parameter("_segmentLength", int[].class, nodeLength, null));
params.addElement(new Parameter("_lengthOfDay", int[].class, lengthOfDay, null));
params.addElement(new Parameter("_roadClass", String.class, rtype, null));
params.addElement(new Parameter("_surfaceCondition", String.class, surfaceWidth, null));
params.addElement(new Parameter("_roadGradient", String.class, gradFact, null));
params.addElement(new Parameter("_operationalCondition", String.class, operationalCondition, null));
params.addElement(new Parameter("_roadWidth", String.class, composition, null));
params.addElement(new Parameter("_vehicleComposition", String.class, composition, null));
call.setParams(params);
// detail call
try {

// call constructor
call.setMethodName("SingleRateOfAdvance");
Response resp = call.invoke(url, "");
SOAPHTTPConnection st = (SOAPHTTPConnection)call.getSOAPTransport();
st.setMaintainSession(true);
// call method
        call.setParams(null);
call.setMethodName("getRateOfAdvanceDetail");
resp = call.invoke(url, "");
if (resp.generatedFault()) {
    String code = resp.getFault().getFaultCode();
    String desc = resp.getFault().getFaultString();
    out.println(code + " " + desc);
}
else {
    Parameter ret = resp.getReturnValue();
    Object value = ret.getValue();
    out.println("<pre><h2>SOAP DETAIL</h2>\n"+value+"</pre>");
}
}
catch (SOAPException e){
out.println( "Caught SOAPException (" + 
               e.getFaultCode() + "): " +
       e.getMessage() );
}
%

When I run this client I get the following exception returned:
SOAP-ENV:Server.Exception: gov/dia/RateOfAdvance
I was surprised that getFaultString() returned:
gov/dia/RateOfAdvance
because the service is based on a class named SingleRateOfAdvance. RateOfAdvance is an abstract class that SingleRateOfAdvance extends.

I am also using Apache Tomcat webserver. The only information I have found in the log file pertinent to this problem is:

Any assistance would be greatly appreciated.

This question has been answered.
The RateOfAdvance.class file was not copied to the necessary sub directory.
