I am new to web services, having failed to get an axis working example running from a book (Developing Java Web services). I have tried my own. At least now I get errors, but I really can't understand what the problem is. I would really appreciate some help.
The error is telling me that the method I am trying to call "getSchema()" dose not exist (faultString: No such operation 'getSchema') more details below.
I really would appreciate any help.
Thanks in advance...
I am using axis1_1RC2 in tomcat 4.1.18 on windows XP.
my service class is:
***************************
package com.wordmap.apiservice;
import com.wordmap.navigation.WordmapFacade;
public class WordMapAPIService {
String schema;
public String getSchema() throws Exception {
ApiXMLHelper axh;
try {
axh = new ApiXMLHelper();
schema = axh.getShemasXMLasString();
} catch( Exception te){
te.printStackTrace();
}
return schema;
}
}
Its wsdd is:
<deployment name="mtest" xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"
xmlns:xsd="http://www.w3.org/2000/10/XMLSchema"
xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance">
<service name="wmrpcservice" provider="java:RPC">
<parameter name="className" value="com.wordmap.apiservice.WordMapAPIService"/>
<parameter name="allowedMethods" value="*"/>
</service>
</deployment>
I deployed it using:
java org.apache.axis.client.AdminClient -lhttp://localhost:8181/axis/services/AdminService deploy.wsdd
My client class is:
***************************
package com.wordmap.client;
import org.apache.axis.AxisFault;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;
import javax.xml.rpc.ParameterMode;
import javax.xml.namespace.QName;
import java.net.URL;
public class WordMapPublishedDataClient {
public String getSchema() throws Exception {
String endpoint = "http://localhost:8181/axis/services/wmrpcservice";
Service service = new Service();
// Create the SOAP request message
Call call = (Call) service.createCall();
// Set the provider location
call.setTargetEndpointAddress( endpoint );
// Set the service name and methods
call.setOperationName( new QName("wmrpcservice", "getSchema") );
//Object responseObj = call.invoke( new Object[] {new Integer(productID)} );
Object responseObj = call.invoke( new Object[] { null });
// Retrieve the values from the response object
String respString = (String) responseObj;
return respString;
}
public static void main(String args[]) {
try {
WordMapPublishedDataClient wmpdc = new WordMapPublishedDataClient();
String val = wmpdc.getSchema();
System.out.println("Schema Name: " + val);
}
catch( Exception e ) {
if ( e instanceof AxisFault ) {
System.err.println( ((AxisFault)e).dumpToString() );
} else
e.printStackTrace();
}
}
public WordMapPublishedDataClient() {
}
}
I ran it using:
java com.wordmap.client.WordMapPublishedDataClient
This is the error:
