Hi Arvind

Without seeing the code its hard to diagnose.

If you are using MessageBox in an MVC application it may be a scope "this" issue.

One quick fix would be to ensure the correct context is used

   sap.ui.commons.MessageBox.alert("Hello World!", $.proxy(fnCallback,this));

see http://api.jquery.com/jQuery.proxy/

Another would be

this.msg = 'Hello World";
var that = this;
..
function fnCallback(){
     alert(that.msg);
}

Again without seeing code, i am guessing

JSP

It's pretty hard to answer your question without more information. Can you share a small code example that demonstrates the problem?
