hi,

i am using tomcat 4.1, jdk 1.4 and soap 2.3.1...i
have set classpath all required jar files
(mail.jar,activation.jar,xerces.jar,soap.jar) and deploy
service on server successfully...

Service program---


/** Simple test of String and String[] parameters and return values */

public class HelloService1

{

/** Says hello to one person */

public String helloString(String name)

{

return "Hello, " + name;

}

/** Says hello to many people */

public String[] helloStringArray(String[] names)

{

String[] ret = new String[names.length];

for (int i = 0; i < names.length; i++)

ret[i] = "Hello, " + names[i];

return ret;

}

}



Client program---



import java.net.*;

import java.util.*;

import org.apache.soap.*;

import org.apache.soap.rpc.*;

import org.apache.soap.encoding.*;

/** Simple test of String and String[] parameters and return values */

public class HelloClient1

{

/** Gets the type of a class as a string */

private static String getType(Class c)

{

if (!c.isArray())

return c.getName();



return "array of " + getType(c.getComponentType());

}



/** Gets the value of an object as a string */

private static String getValue(Object o)

{

Class c = o.getClass();

if (!c.isArray())

return "'" + o.toString() + "'";



String ret = null;

Object[] oa = (Object[]) o;

for (int i = 0; i < oa.length; i++) {

if (ret == null)

ret = "[" + getValue(oa[i]);

else

ret = ret + ", " + getValue(oa[i]);

}

return ret + "]";

}



/** Makes a SOAP call */

private static void makeCall(String targetURI,

String methodName,

String encodingStyleURI,

SOAPMappingRegistry smr,

Vector parameters,

String endpointURL) throws Exception {

Call call = new Call();

call.setTargetObjectURI(targetURI);

call.setMethodName(methodName);

call.setEncodingStyleURI(encodingStyleURI);

if (smr != null)

call.setSOAPMappingRegistry(smr);

call.setParams(parameters);



System.out.print("Call to method '" +

methodName +

"' of object '" +

targetURI + "' ");

Response resp = call.invoke(new URL(endpointURL),

targetURI);

// System.out.println(resp);

if (resp.generatedFault())

{

Fault fault = resp.getFault();

System.out.println("faulted:");

System.out.println(" Code = " + fault.getFaultCode());

System.out.println(" String = " + fault.getFaultString());

}

else

{

Parameter result = resp.getReturnValue();

Object value = result.getValue();

System.out.println("returned:");

System.out.println(" Type = " + getType(value.getClass()));

System.out.println(" Value = " + getValue(value));

}

}



/** Tests a service using String and String[] parameters and return values */

public static void main(String[] args) throws Exception

{

if (args.length < 2)

{

System.err.println("Usage: java HelloClient1 SOAP-router-URL name [name ...]");

System.exit(1);

}



String targetURI = "urn:hello1";

String methodName = "helloString";

String encodingStyleURI = Constants.NS_URI_SOAP_ENC;

Vector params = new Vector();

params.addElement(new Parameter("name", String.class, args[1], null));

String endpointURL = args[0];

// System.out.println(params);

// System.out.println(endpointURL);

makeCall(targetURI, methodName, encodingStyleURI, null, params, endpointURL);



methodName = "helloStringArray";

String[] names = new String[args.length - 1];

for (int i = 0; i < args.length - 1; i++)

{

names[i] = args[i + 1];

// System.out.println(names[i]);

}

params = new Vector();

params.addElement(new Parameter("names", names.getClass(), names, null));



makeCall(targetURI, methodName, encodingStyleURI, null, params, endpointURL);

}

}







when i run client program then i recieved an error.. Error is......
