[SOLVED] http request

[DonCash]

So your looking to read in all the HTML and add the entire output as one String?

What are you going to do with this String?

[Eranga]

ah, actually I'm displaying that on a JEditorPane. So I can work with HTML code there.

[Eranga]

I got the point. I couldn't concatenate those strings, because of the tab space effecting. I solved my problem. It's working fine.

[DonCash]

Nice one Eranga. :D

[Eranga]

Yep, up to now it's working really well. :)

If you get your own test code from the Post Office and use the link to their DLL, this would work.

public void doPost() {
try {
// Construct data
String data = URLEncoder.encode("API", "UTF-8") + "=" + URLEncoder.encode("ZipCodeLookup","UTF-8");
data += "&";
data += URLEncoder.encode("XML", "UTF-8") + "=" + URLEncoder.encode("<ZipCodeLookupRequest USERID=\"??????????\"><Address ID=\"0\"><Address1></Address1><Address2>6406 Ivy Lane</Address2><City>Greenbelt</City><State>MD</State></Address></ZipCodeLookupRequest>", "UTF-8");

// Send data
URL url = new URL("<post office API DLL LINK>");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(data);
wr.flush();

// Get the response
BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
System.out.println(line);
}
wr.close();
rd.close();
} catch (Exception e) {
e.printStackTrace();
}

}
}

You may want to look at the Apache httpclient code library.

The pure Java stuff works for trivial servers, but tends to break down on real web pages from real servers. The Apache code handles "chunked" results, encoding, compression, and lots of other stuff.

Of course, if you control both ends, the response from the Web server really should be XML so you can parse it on the client side

As fishtoprecords said look into HttpCleint,Here is the brief tutorial for HttpClient,it is very easy to use it:

Thanks for the tutorial serjant. I've already found that when I post at the time around I start this thread. :) Did you find that any server side application related to this tutorial.

[fishtoprecords]

Hmm, I got the point. Say I want to return that String, I mean the whole String. Then what is the easiest way to do it.

Change his loop to append the incomming string to a StringBuilder.

Thanks fishtoprecords, actually I've solve the question here. So it's time to mark it as solved. :)
