Opening an URL from java

Question

we\'re writing an open-source jdbc driver for bigquery, and ran into the following problem:

We want to authorize our driver with Oauth 2 as an installed application.

Answer 1

Basically sounds good but here is another way if you want to open using specific browser (if more than one browser in the system)

String url = "http:/devmain.blogspot.com/";
String[] browsers = { "firefox", "opera", "mozilla", "netscape" }; // common browser names
String browser = null;
for (int count = 0; count < browsers.length && browser == null; count++)
  if (Runtime.getRuntime().exec(new String[] { "which", browsers[count] }).waitFor() == 0)
    browser = browsers[count]; // have found a browser
Runtime.getRuntime().exec(new String[] { browser, url }) // open using a browser

Answer 2

Here is a suggestion from a different perspective. (Not sure if this is an option to you)

The problem that you are trying to solve is to use Oauth 2 and authentication mechanism. Instead of opening a browser capturing its response. There are already available libraries like Apache amber which do this purely in java.

Here is an official Amber Example that you can refer to.

Answer 3

Using java.net.HttpURLConnection

URL myURL = new URL("http://example.com/");
    URLConnection myURLConnection = myURL.openConnection();
    myURLConnection.connect();
