Very Ugly!

Why do you need JspWriter? What are you actually trying to do?

Here is an example program:

You're not quite getting what's happening when your JSP is translated
into a .java file. Take a look at the work file to see what happens,
it can be enlightening (in Tomcat, under Linux, the work (.java) file
s/b in someplace like /usr/local/tomcat/work/Catalina/...).

As you noticed, your page is essentially the following, which makes
the output a little less confusing:

  public void printThree(javax.servlet.jsp.JspWriter out)
    throws {
  };/*End printThree*/

  public void printTwo(javax.servlet.jsp.JspWriter out)
  };/*End printTwo*/

  public void printOne(javax.servlet.jsp.JspWriter out)
  };/*End printThree*/
    <meta http-equiv="Content-Type" content="text/html;
    <title>JSP Page</title>
      <p>1'st method</p>
      <p>2'nd Method</p>
      <p>3'rd method</p>

All of this is such fugly JSP code! Yecch.

JSPs are primarily for handling the view component of a web app. You
really shouldn't have any scriptlet in them, much less be messing
around with method definitions.

That you find yourself having to look at the precompiler .java output
is telling. I suggest either using JSTL and EL (they let you write
functions) or skipping JSP and writing the code as a .java-sourced
