httpurlconnection usage

[mahesh narayan]

Hi

i have a servlet(in websphere app server) which gets some data from the database. I need to pass this data to a jsp page(in ibm http server) running on a different serverand show the jsp page on the browser.I come to understand tht HttpURLConnection() can be used for the same. But i am not clear on how to acheieve this using httpurlconnection().

Any inputs on the same will be valuable.

thanks
Mahesh

just found this...

// make the connection
String urlstring = "http://www.yoursite.com:80/somedir/file.jsp";
String parameters = "key1=value1&key2=value2";
URL url = new URL(urlstring);
HttpURLConnection conn = (HttpURLConnection)url.openConnection();
 
// post the parameters
conn.setDoOutput(true);
OutputStreamWriter wr;
wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(parameters);
wr.flush();
wr.close();
 
// now let's get the results
conn.connect(); // throws IOException
int responseCode = conn.getResponseCode(); // 200, 404, etc
String responseMsg = conn.getResponseMessage(); // OK, Forbidden, etc
BufferedReader br = new BufferedReader(
new InputStreamReader(conn.getInputStream()));
StringBuffer results = new StringBuffer();
String oneline;
while ( (oneline = br.readLine()) != null) {
results.append(oneline);
}
br.close();
 
// wrap the whole thing in a try {}
// catch the following exceptions:
// MalformedURLException
// UnknownServiceException
// IOException
