[Simple-support] Need to use simple to write an inputStream to some useable xml form

[meghiddo <mat...@ho...>]

SO I have a method that uses httpclient to get data from a web service.  The
data is stored on the web service in an xml format.  I can use httpclient
getMethod to retrieve this xml either as a stream or a string.  
So I have that data stored in a varable, called responseBody.
Now I need to convert that into xml form.  If I try to add the current value
of responseBody to a list (when it is a String) the list does print out the
data and it does look like xml.  But for some reason it is not being
recognized as xml.  It is being recognized as a String, and even though that
String looks like xml, it is not being recognized as such ny a rich:tree

The final goal is to somehow bind this xml to a list (or some other possible
value), which I can then bind to a richfaces tree through a backing bean.  

So here is my method that gets the responseBody from the web service:

public void load(){
		// Create an instance of HttpClient.
		 HttpClient client = new HttpClient();
		 SimpleXml access = new SimpleXml();
		
	 	 // Create a method instance.
	     GetMethod method = new GetMethod(devicesUrl);
	     
	     InputStream responseBody = null;
		 
	     
						     try {
								 // Execute the method.
								 int statusCode = client.executeMethod(method);
								 //System.out.println( method.getStatusCode());
								
								 if (statusCode != HttpStatus.SC_OK) {
								     System.out.println("Method failed: " + method.getStatusLine());
								 }
								
								 // Read the response body.
								 responseBody = method.getResponseBodyAsStream();
								 
								 
								 //System.out.println("printing current value of
method.getResponseBodyAsString from httpclient class "+
										 //method.getResponseBodyAsString());
								     } catch (Exception e) {
								             // TODO Auto-generated catch block
								                 e.printStackTrace();
								     }
			     
	    System.out.println("printing InputStream responseBody from httpclient
class: " + responseBody.toString());
	    
	    
	}

This seems to be working OK.  Through various tests I have been able to
print out the value of resposeBody and it does return this:

<?xml version="1.0" encoding="UTF-8"?>
<deviceCollection>
  <device>
    <deviceId>exampleDevice1</deviceId>
    <name>Example Device 1</name>
  </device>
  <device>
    <deviceId>WSN-Module-8F3A-D247-4B99</deviceId>
    <name>WSN CRio Device</name>
  </device>
</deviceCollection>


That is if I get responseBody as a String.  If I get responseBody as a
stream, I cant print out the value but I am guessing it would be the same,
just in  a stream form right?  If I try to print it as a Stream it gives me
some odd print out that doesnt mean much, I just know it does not mean null.

So assuming that is true, I have my variable responseBody, either as a
String or Stream depending on what I do, and it holds the xml I printed
above.

Now I need simple to take that data in, and output it in some kind of xml
form that I can use.  Although Im not sure what yet...

Like I said, the end goal is to use this xml to populate a rich tree.  If I
leave responseBody as a String, and use that to populate the tree it gives
me a one node tree that has all of that xml text on one line...not too
useful.

>From what I understand from the jboss forum, if I can get some form of xml
bound to the rich tree then I can use this line on my jsf page to do what I
need:

<rich:recursiveTreeNodesAdaptor roots="#{recTreeBean.data}" var="item"
nodes="#{item.name}" />

Ideally that will make a nice tree.  If that line were to use the xml I
printed from above, the result Im hoping for would be a tree like this:

-exampleDevice1
---Example Device 1
-WSN-Module-8F3A-D247-4B99
---WSN CRio Device


But I just cant get this working,
so any help at all anyone might have would be great.  I mean anything, I
have tried all I can think to do, so even if you have help pretaining to the
tree rather than simpleXml that is great

Thanks
