Client Side Exception

[Sandeep Advani]

Hello Friends

I have written a client using Apache AXIS client side API to access a Web Service After running the client, I receive following exception:

java.lang.IllegalAccessException: Class org.apache.axis.providers.java.JavaProvi
der can not access a member of class LookupService with modifiers ""

My client side code is

  
 
public class LookupClient
{
private static String line = new String("Hello");

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

        try {
 
Options options = new Options(args);            
            String endpointURL = options.getURL();
System.out.println("End point URL is :" + endpointURL);           
            args = options.getRemainingArgs();
            
            Service  service = new Service();
            Call     call    = (Call) service.createCall();
 
            call.setTargetEndpointAddress( new java.net.URL(endpointURL) );
            call.setOperationName( new QName("LookupService", "servicesAvailable") );
            call.addParameter( "arg1", XMLType.XSD_STRING, ParameterMode.IN);
            call.setReturnType( org.apache.axis.encoding.XMLType.XSD_STRING );
 
System.out.println("Invoking...");
            String res = (String)call.invoke( new Object[] { line } );
            System.out.println("Waiting...");
            System.out.println("\n" + res);
        } catch (Exception e) {
            System.err.println(e.toString());
        }
    }
}
 

I can see the web service being deployed by targetting the http:\\localhost:8080\axis on the browser.

Any idea what might cause this exception?

Thanks

I think you have an exception generated by the service, not the client side. I suspect that the method you are trying to access does not have the "public" access modifier. Did you write LookupService or get it from somewhere else?

Hello Bill,

Lookup Service was written by me. Code snippet is as follows.

  
public class LookupService 
{
AgentAddress addr = new AgentAddress();
ServiceJdbc services = new ServiceJdbc();
private StringBuffer service_detail;
 
LookupService() { }
 
LookupService(String className, String methodName, String returnType, String param) {
addr.setClassName(className);
addr.setMethodName(methodName);
addr.setReturnType(returnType);
addr.setParameters(param);
addr.put();
}
 
public StringBuffer lookupAddress() {
service_detail = new StringBuffer();
service_detail.append(addr.getClassName());
service_detail.append("\n");
service_detail.append(addr.getMethodName());
service_detail.append("\n");
service_detail.append(addr.getReturnType());
service_detail.append("\n");
service_detail.append(addr.getParameters());
return service_detail;
}
 
//This method will be the web-service where clients will connect
//to learn services available. Connect to ServiceJdbc and return all methods present.
 
//Think about passing arguements if agent is a new functionality.
 
/*public String servicesAvailable(String test) 
{
  System.out.println("Test is : " + test);
  try
  {
  AgentAddress[] agents = new ServiceJdbc().returnAgents();
StringBuffer agent = new StringBuffer();
int count = new ServiceJdbc().numOfAgents();
 
for(int i = 0; i < count; i++) 
{
agent.append(agents[i].getClassName());
agent.append(" ");
agent.append(agents[i].getMethodName());
agent.append(" ");
agent.append(agents[i].getReturnType());
agent.append(" ");
agent.append(agents[i].getParameters());
agent.append(" ");
}
String agentDetails =  agent.toString();
return agentDetails;
  }
  catch (Exception e)
  {
  return null;
  }
}*/
 
/*public static void main(String[] args) {
LookupService test = new LookupService();
test.servicesAvailable();
new LookupService().servicesAvailable();
}*/
}
 

Public modifier is there in order to expose the services. Moreover, the services seem to be deployed when I hit the browser hosting Web Services.

Thanks
