Tags: URL Relative Path, Java URL Path Recently I was trying to write an Applet to display an Image that is stored in Web server (from the same location of Applet that is to be downloaded onto the user's browser). Idea is to dynamically locate the URL relative path for the image without any sort of hard coding the complete URL within the Applet code or placing it as a variable in the HTML Applet tag as Parameter.

Like for example, URL url = new URL("http://<WEB_HOST_NAME>/test.png"); or <applet code="test" archive="test.jar" codebase="/" width="150" height="50" name="onlinestatus"> <param name="url" value="http://www.interview-questions-tips-forum.net/example/"> </applet> I treat these two solution for retrieving URL of the image as hard coded. Solution should be as such so that it enables same Applet to be used in various web server without any change in the URL relative path that is present inside Applet code, such as mentioned below: Image img = Toolkit.getDefaultToolKit() .getImage(new URL(getCodeBase()+"test.png")); getCodeBase method is available in java.applet.Applet api from Java Platform. It returns the URL path of the location from where the user defined Applet is downloaded from and test.png is the image stored in the same location in web server directory/folder.

URL relative path is very much useful while developing Applets those are required to refer resources at server side, in order to perform some functionality, such as displaying Images, playing/streaming audio, video files, located at webserver relative path.
