When I try to compile the provider class, in this example, this java file:
package tesi;
import java.io.*;
import java.util.*;
import prova.*;
public class application_controller {
public GetComp() {
servizio s = new servizio();
composizione c = new composizione(
s.c_Nomefile1, s.c_Nomefile2, s.c_Nomefile );
}
}
I receive this error:
application_controller.java:8: invalid method declaration; return type
required
public GetComp() {
^
1 error
HOW CAN I SOLVE THIS PROBLEM?

Subject: Re: problem in deploying a web service
With Apache SOAP 2.3.1, you cannot have whitespace in the faultListener
element. The problem is fixed in the current code base.
You need to change
<isd:faultListener>
org.apache.soap.server.DOMFaultListener
</isd:faultListener>
to
<isd:faultListener>org.apache.soap.server.DOMFaultListener</isd:faultListene
r>
then re-deploy (undeploy followed by deploy with new dd file) the service.

Subject: problem in deploying a web service
I want to deploy a service. I executed the following operations:
- deploying with Apache SOAP using a deployment descriptor file named
WebService:
<isd:service
xmlns:isd="http://xml.apache.org/xml-soap/deployment";
id="urn:CompService">
<isd:provider type="java"
scope="Application"
methods="getComp">
<isd:java class="tesi.application_controller"
static="false"/>
</isd:provider>
<isd:faultListener>
org.apache.soap.server.DOMFaultListener
</isd:faultListener>
<isd:mappings>
</isd:mappings>
</isd:service>
- invoking the getCount method using this java file named GetCompApp
package tesi;
import java.net.*;
import org.apache.soap.*;
import org.apache.soap.rpc.*;
public class GetCompApp {
public static void main(String[] args)
throws Exception {
URL url =
new URL(
"http://localhost:8080/soap/servlet/rpcrouter";);
Call call = new Call();
call.setTargetObjectURI("urn:CompService");
call.setMethodName("getComp");
try {
Response resp = call.invoke(url, "");
Parameter ret = resp.getReturnValue();
Object value = ret.getValue();
System.out.println("Result is " + value);
}
catch (SOAPException e) {
System.err.println("Caught SOAPException (" +
e.getFaultCode() + "): " +
e.getMessage());
}
}
}
but I received this exception:
Caught SOAPException (SOAP-ENV:Protocol): Unsupported response content type
