[JSP] Calling a user defined function in a jsp

[whoopy_whale]

Please tell me how to call a user defined function in jsp?

Is it possible to write functions in jsp in a similar fashion of php? Or do we need to create it in a java file?

Please respond.

You can do a couple of things really, you can have a servlet which you make calls to, you could have a bean which you instantiate declaratively, or you could use scripting blocks.

Scripting blocks work like follows:

<%
	 public String sayHello(String myName)
	 {
		  return "Hello " + myName;
	 }
%>

Please tell me how to call functions from a servlet. I was under the impression that servlets can be used to process form data only.

I am migrating from PHP to JSP... so i have some doubts here...

Plz help me...

I don't mean to be rude, but have you actually spent some time looking into what JSP does? Or have you come straight on here for answers without spending some time doing research yourself?

Generally, a Servlet (which can be a .jsp page, or a compiled class) receives a request and returns a response. You should research Java beans, and J2EE...

Thats ok :)

I was actually looking for a quick solution...

I started off with JSP,and then worked on PHP and now back to JSP..and I really need to do some research...

Thanks for the reply...
