RestTemplate - How can I?

[Mimi Tam]

My RestTemplate client needs to "bring up" a HTTP Request Form (for input) created by the Web Service, enters data and hit the SEND button via the browser. The Web Service will process Form data, create an HTTP Response message in XML and send back to the RestTemplate client.

Two questions:

1. How can the RestTemplate client "bring up" this Form (*.jspx in the WS) created by the Web Service to the browser?
2. From the Web Service's HttpRequest controller at POST (after input data), how can I trigger the GET, POST handlers from the Web Service's HttpResponse controller?


My Client App:

public class ClientApp
{
	public static void main( String[] args )
	{
		ApplicationContext applicationContext = new ClassPathXmlApplicationContext(	"applicationContext.xml" );
		DemoClient demoClient = applicationContext.getBean( "demoClient", DemoClient.class );
				
		// Bring up blank HTTP Request Form (from WS) in browser
		//URI postedUri = demoClient.postLocation();
		
		HttpReqMsg1 req = demoClient.getHttpReqMsg1Form();
		
		HttpRspMsg1 httpRspMsg1 = demoClient.getResponse();
		System.out.println( "HttpRspMsg1: " + httpRspMsg1 );
		
		//HttpReqMsg1 httpReqMsg1 = demoClient.getRequestById(1);
		//System.out.println( "HttpReqMsg1: " + httpReqMsg1 );
	}
}

My demo client POJO:

@Component( "demoClient" )
public class DemoClient
{	
	@Autowired
	protected RestTemplate restTemplate;

	final String reqFormUrl = "http://localhost/demo/httprequest/form/";
	final String demoUrl = "http://localhost/demo/";

	//public URI postLocation()
	//{
	//	return restTemplate.postForLocation(reqFormUrl, null);
	//}

	public HttpRequest getHttpRequestForm()
	{
		return restTemplate.getForObject( demoUrl + " createForm", HttpRequest.class);
	}
	
	public HttpRspMsg1 getResponse()
	{
		return restTemplate.getForObject( demoUrl + "httpResponse", HttpResponse.class);
	}

	public HttpRspMsg1 getResponseById( long id )
	{
		return restTemplate.getForObject(demoUrl + "httpResponse/{id}", HttpResponseMsg1.class, id );
	}

	@SuppressWarnings( "unchecked" )
	public HttpRequest getRequestById( long id )
	{
		return restTemplate.getForObject(demoUrl +  "httpRequest/{id}", HttpRequest.class, id );
	}	
}

HTTP Request Controller in the Web Service:

public class HttpRequestController1 {		
	
	@RequestMapping(value = "/httprequest", method=RequestMethod.POST)
	public @ResponseBody String createResponse(@Valid HttpRequest  	HttpRequest httpRequest) {
        if (httpRequest == null) 
        	throw new IllegalArgumentException("A HTTP Request Message is required");
        httpRequest.persist();   //Http Response msg is within the Request class
        //return "redirect:/httpreqmsg1/" + httpReqMsg1.getReq1Id();

	    return httpRequest.createResponse();	  // <-------send HTTP Response Msg to client for client to display.  @ResponseBody is XML
    }
	
	@RequestMapping(value="/httprequest/{id}", method=RequestMethod.GET)
	public @ResponseBody String show(@PathVariable("id") Long req1Id, ModelMap modelMap) {
		     if (id == null) throw new IllegalArgumentException("An Identifier is required");
		    	HttpRequest req = new HttpRequest();
		        modelMap.addAttribute("httprequest", req.findHttpRequest(id));
		        return "httprequest/show";
		    }	
	
		@RequestMapping(value = "/httprequest/form", method = RequestMethod.GET)
	    public String createForm(ModelMap modelMap) {
		      modelMap.addAttribute("httprequest", new HttpRequest());
		      return
                ............ 

HTTP Response Controller in the Web Service:

<HTTP Response Controller all the same as the HTTP Request Controller just a name difference.

HTTP Request POJO:

public Class HTTPRequest() {

...............
		@OneToOne(cascade = CascadeType.ALL)
		@JoinColumn ( name = "id", insertable = false, updatable=false)
		private HttpResponse httpResponse; 

Any help will be greatly appreciated.
