How to replace a string in jsp

Question

I have a string url like http://google.com. I need to remove 'http://' from the URL. I have tried the method .replace("http://",""), but it is not working.

Web web = org.getWeb();
webUrl = web.getUrl();
out.println("webUrl :"+webUrl );  // here it prints:: http://google.com
webUrl.replace("http://","");
out.println("webUrl :"+webUrl );  // here also it prints:: http://google.com

Try:

webUrl = webUrl.replace("http://","");

As replace returns the replaced string

You need to do like following.String is immutable class.replace will return you new String object.

webUrl = webUrl.replace("http://","");

Refer String is immutable. What exactly is the meaning?
