Velocity / XML response
Hi everyone, I'd be grateful if someone could help me out here. I use apache velocity to generate an xml request to send to a gateway which processes the request and sends an xml response. At the moment, the response (xmlString) is outputted to the browser as a string (see code below).
I want to separate out the elements in the response and display them in a more readable format on the browser eg.
Name = "xyz"
Address = "xyz"
Here is a snippet of what I have. What is the quickest way to extract the individual elements from the xml response and display them?
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
try {
DiskFileItemFactory factory = new DiskFileItemFactory();
factory.setSizeThreshold(4096);
factory.setRepository(new File( _FOLDER_UPLOAD ));
PrintWriter writer = response.getWriter();
ServletFileUpload upload = new ServletFileUpload(factory);
upload.setSizeMax(60000000);
String xmlResult = executeCheck( upload, request);
manageResponse( writer, xmlResult);
} catch (FileUploadException e) {
e.printStackTrace();
}
}
private void manageResponse(PrintWriter writer, String xmlResult) {
writer.println(xmlResult);
writer.flush();
}
private String executeCheck( ServletFileUpload upload, HttpServletRequest request ) throws FileUploadException, IOException {
List items = upload.parseRequest(request);
Iterator iter = items.iterator();
while( iter.hasNext() ) {
System.out.println(items.toString());
FileItem item = (FileItem)iter.next();
if ( !item.isFormField() && item.getFieldName().equalsIgnoreCase("upload") ) {
InputStream in = item.getInputStream();
VasGatewayClient wsC = new VasGatewayClient( in, _URL );
return wsC.send();
}
}
return null;
}
