sending xml to servlet

[David Westbrook]

hey all,

I have an xml document containing data in html page, and I would like to send that to a servlet.

I'm thinking I can do it one of two ways.

ONE:

   
 
        // NOTE: xmlhttp is a XMLHttpRequest object
 
xmlhttp.open("POST","/test/src/XMLServlet",true);
xmlhttp.setRequestHeader("Content-Type", "text/xml");
xmlhttp.send(xmlDoc);
 

I have seen supposedly working examples of this, but they were IE specific, and I'm looking for something that complies w/w3c.

and then on servlet I do something like:

    
 
Document doc = docBuilder.parse(request.getInputStream());
 

I have a feeling that I need to alter the setRequestHeader, so any suggestions would be helpful.

The other way I think would be possible would be to turn the xml doc into a string and send it like this:

    
 
str = "servleturl?" + xmldoc.toString();
 
// then do a post using str as the url
 

and then do something on servlet like:

    
 
Document doc = docBuilder.parse(request.getQueryString());
 

problem w/this is xmldoc doesn't have toString().

Any help (thoughts, comments, examples, good references) would be appreciated.

As to the client side in the browser, any code that does this will have some IE-specific stuff; that's just how XMLHttpRequest is implemented. But that's generally abstracted away by the thinnest layer on top of it; see this for code that works in all browsers.

I have it working perfectly. I will post more details when I get the time. Check back in a couple of days if you're interested.

Glad to hear that you have it working. One thing you might want to consider, XML compresses well, there is lots of redundancy, so the built in Java gzip code can save a lot of time and bandwidth.
