Two typical causes of this problem:
1. The servizio.class file is more than one place, with an older version with a
different method signature being loaded by Tomcat.
2. You changed servizio.java, compiled to a new servizio.class, copied the file to
.../webapps/soap/WEB-INF/classes, but did not force Tomcat to re-load it. I usually
just restart Tomcat to be sure the newest version is loaded.

Subject: method not founded
I have written this client:
import java.net.*;
import java.util.*;
import java.io.*;
import org.apache.soap.*;
import org.apache.soap.rpc.*;
public class Client {
public static void main(String[] args)
throws Exception {
String c_Nomefile="";
String [] lista = new File(".").list(); //crea lista
URL url =
new URL(
"http://localhost:8080/soap/servlet/rpcrouter";);
System.out.println("ELENCO SERVIZI:");
for(int cx=0; cx<lista.length; cx++)
if ( new File(lista[cx]).isFile() ) //verifica se è
file
if ( lista[cx].toLowerCase().lastIndexOf(".owl") >= 0) //e con
estensione .owl
System.out.println((" * "+lista[cx]+" ").substring(0,20));
System.out.print("Servizio principale: ");
BufferedReader in1= new BufferedReader(new InputStreamReader(System.in));
String c_Nomefile1 = in1.readLine();
System.out.print("Servizio da comporre: ");
BufferedReader in2= new BufferedReader(new InputStreamReader(System.in));
String c_Nomefile2 = in2.readLine();
c_Nomefile = c_Nomefile1 + c_Nomefile2;
Call call = new Call();
call.setTargetObjectURI("urn:Composizione");
call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
Vector params = new Vector();
params.addElement(new Parameter("file1", String.class, c_Nomefile1, null));
params.addElement(new Parameter("file2", String.class, c_Nomefile2, null));
call.setParams(params);
try {
call.setMethodName("metodi_xml");
Response resp = call.invoke(url, "");
if (resp.generatedFault()) {
Fault fault = resp.getFault();
System.err.println("Generated fault: " + fault);
} else {
Parameter ret = resp.getReturnValue();
Object value = ret.getValue();
System.out.println("comp " + value);
}
}
catch (SOAPException e) {
System.err.println("Caught SOAPException (" +
e.getFaultCode() + "): " +
e.getMessage());
}
}
}
The service is:
public class servizio {
public int metodi_xml(String file1, String file2) {
int a;
a=0;
return a;
}
}
The .dd file is:
<isd:service
xmlns:isd="http://xml.apache.org/xml-soap/deployment";
id="urn:Composizione">
<isd:provider type="java"
scope="Application"
methods="metodi_xml">
<isd:java class="servizio"
static="false"/>
</isd:provider>
<isd:faultListener>org.apache.soap.server.DOMFaultListener</isd:faultListener>
<isd:mappings>
</isd:mappings>
</isd:service>
All this file are in:%CATALINA_HOME%\webapps\soap\WEB-INF\classes; when I try java
Client, I receive this exception:
