Question

I want to create a Login Form in Swing JAVA and when the user clicks on the submit button it should use a GET call to GET the user information from a URL.
My login form is having two fields:
username:
password:
and “submit” button

I have used the following code. I am working in NetBeans 7.1.2 .I new to Java.

 public void actionPerformed(ActionEvent ae)throws IOException
  {
 String value1=text1.getText();
String value2=text2.getText();
URL url = new URL("http://link?      userName=value1&password=value2");
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection(); 
httpCon.setDoOutput(true); httpCon.setRequestMethod("GET");
OutputStreamWriter out = new OutputStreamWriter( httpCon.getOutputStream());
System.out.println(httpCon.getResponseCode());
System.out.println(httpCon.getResponseMessage());
out.close(); 

}

but it is not working .
Can anyone please tell me where I am wrong OR can give me better way to do this.

class Login extends JFrame implements ActionListener

I am using this but now I am getting error code 404 whereas if I typed the URL in the browser it is giving me the correct result.

Answer 1

This is because you coded the litterals “value1” and “value2” and not their variables in the URL. Try this instead:

URL url = new URL("http://wisekar.iitd.ernet.in/active/api_resources.php/method/user?userName="+value1+"&password="+value2);

Note that you should use a URLEncoder (with charset UTF-8) to encode those values.
