Servlet to handle XML Requests and Responses!

[FOR111]

HI All,

I have a problem...i have to design a servlet which handles xml requests and responses. The requests are received via http, they are parsed and a function should handle the request (ie Add User etc) then a response should be created (xml) and sent via the same http request.

Is there anyone who can give me some examples or maybe a way to go so i can get started!? thanks for your help..i'm quite new to java per se

Regards
Nick

Something to start you off ...

In your doPost() method :

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

	// read the data from the stream which should be your XML
	// and save it somewhere (in memory or to disk)
	DataInputStream is = new DataInputStream(request.getInputStream());
	int inlen = request.getContentLength();
	byte[] xmlRequestData = new byte[inlen];
	is.readFully(xmlRequestData);
	is.close();	
	is.close();
	
	

	// Then parse your XML which is held in memory in 'xmlRequestData'

	// Perform your required action

	// Create the response XML and convert it into a byte[]

	// Write the data
	response.setContentType("text/xml");

	OutputStream os = response.getOutputStream();
	os.write(xmlResponseData);
	os.flush();
	os.close();
	
}

Thanks sedj...thats already a big start thanks!

What i was after was how i could test, and parse the xml then the equivelent xml will do a certain function for itself!

Thanks again
