We will try out our service first with a simple client that creates a new resource and performs a couple operations on it. This client expects only one argument from the command line, the factory service's URI
package org.globus.examples.clients.FactoryService_Math; import org.apache.axis.message.addressing.Address; import org.apache.axis.message.addressing.EndpointReferenceType; import org.globus.examples.stubs.MathService_instance.GetValueRP; import org.globus.examples.stubs.MathService_instance.MathPortType; import org.globus.examples.stubs.MathService_instance.service.MathServiceAddressingLocator; import org.globus.examples.stubs.Factory.service.FactoryServiceAddressingLocator; import org.globus.examples.stubs.Factory.FactoryPortType; import org.globus.examples.stubs.Factory.CreateResource; import org.globus.examples.stubs.Factory.CreateResourceResponse; /* This client creates a new MathService instance through a FactoryService. This client * expects one parameter: the factory URI. */ public class Client { public static void main(String[] args) { FactoryServiceAddressingLocator factoryLocator = new FactoryServiceAddressingLocator(); MathServiceAddressingLocator instanceLocator = new MathServiceAddressingLocator(); try { String factoryURI = args[0]; EndpointReferenceType factoryEPR, instanceEPR; FactoryPortType mathFactory; MathPortType math;factoryEPR = new EndpointReferenceType(); factoryEPR.setAddress(new Address(factoryURI)); mathFactory = factoryLocator.getFactoryPortTypePort(factoryEPR);
CreateResourceResponse createResponse = mathFactory .createResource(new CreateResource()); instanceEPR = createResponse.getEndpointReference();
math = instanceLocator.getMathPortTypePort(instanceEPR); System.out.println("Created instance.");
// Perform an addition math.add(10); // Perform another addition math.add(5); // Access value System.out .println("Current value:" + math.getValueRP(new GetValueRP())); // Perform a subtraction math.subtract(5); // Access value System.out .println("Current value:" + math.getValueRP(new GetValueRP())); } catch (Exception e) { e.printStackTrace(); } } }

Compile and run the client:
javac \ -classpath ./build/stubs/classes/:$CLASSPATH \ org/globus/examples/clients/FactoryService_Math/Client.java
java \ -classpath ./build/stubs/classes/:$CLASSPATH \ org.globus.examples.clients.FactoryService_Math.Client \ http://127.0.0.1:8080/wsrf/services/examples/core/factory/MathFactoryService
If all goes well, you should see the following:
Created instance. Current value:15 Current value:10
If you run it again, you will get the exact same result. This is because we are creating a new resource every time we run the client.
Created instance. Current value:15 Current value:10
