Introduction

This guide demonstrates how to discover applications available at a GRIA Job Service.

This code requires the TutorialHelpers.java class previously discussed.

The full Java file for application discovery can be downloaded.

Application Discovery Guide

Create a Proxy Factory using the Tutorial Helpers

ProxyFactory proxyFactory = new TutorialHelpers().getFactory();

Use the Proxy Factory to create a Proxy to the Job Service

RemoteJobService jobService = proxyFactory.createProxy(ConversationID.getEPR(JOB_SERVICE_ENDPOINT), RemoteJobService.class);

Call getApplications on the Job Service returning a list of applications available.

String[] applicationList = jobService.getApplications();

Loop through these applications, and print out there details by invoking another method getApplicationMetadataDetailed

if(applicationList.length > 0){
	System.out.println("Found "+applicationList.length+" applications.");
	for(String applicationURI : applicationList){
		Document appDescription = jobService.getApplicationMetadataDetailed(applicationURI);
		String strApplicationDescription = XMLUtils.DocumentToString(appDescription);
		System.out.println("\t"+strApplicationDescription);
	}
}else{
	System.out.println("No applications found on server.");
}
