hi All,

I'm calling a Call_List servlet from a abc.js file as below:

document.frm2.action = "../servlet/min.max.custom.Call_ListCheck';
document.frm2.target='formSaveFrame';
document.frm2.submit();

In Call_List. servlet, I want to make an alert as below:

out.println("

<script language=javascript>"); out.println("alert('SUCCESS')"); out.println("</script>
");

but, this script given in the servlet is not getting called. Only, if abc.js throws some error, this script is being called.

This means, is abc.js holding control? how do i make the alert come up from the servlet.?

Have you looked at what the servlet is returning to the browser? Is it valid?

Symbols like ("< and >") behaves differently while generating js from servlets. Check your script code in JSP which is generated by Servlet.
Try using escape sequence on those symbols..

No, there is nothing special about those characters when emitting response output from a servlet.

That has nothing to do with the angle bracket characters, or even JavaScript. The escaping simply is to allow double quotes in Java strings.
