Can I define a funtion in .jsp file?

For example, in this simple page.
----------------------------------------------------------------------------
<%@ page contentType="text/html;%>
<html>
<body>
<%
    String name = "test name";
    doSomeThing(name);  // <<------------------ question line.
    out.println(name);
 %>
</body>
</html>
----------------------------------------------------------------------------
I want to create a function and call it, such as doSomething(name).

Can I define a function in .jsp file?

such as :
-------------------------------
void doSomeThing(name){
   out.println("name" + name);
}
-------------------------------

Where should I declare function in .jsp file?

Thank you.

ooops my fault....:-)

<!%
 should be...

<%! sorry abt that....

and one more thing..


out.println("oojoij");
will throw the error in the method for the simple reason that out is jsp variable and hence will not be available to the method....
you will  have to right it like


<%!
    public void getThis(JspWriter out){
        out.println("oojoij");
    }
%>
<%@ page contentType="text/html"%>
<html>
<body>
<%
     getThis(out);
%>
</body>
</html>

I have had the same problem. Remove the "public" from the function definition. The function is scoped to the JSP as it is, so public isn't needed.

Hope that helps

The exception needed to handled in oder for compilation.

<%!
    public void getThis(JspWriter out) throws java.io.IOException{
        out.println("oojoij");
    }
%>
<%@ page contentType="text/html"%>
<html>
<body>
<%
     getThis(out);
%>
</body>
</html>
