    Default Turning a JSP into a JAVA file

    Hello, I have a class the purpose of which is to grab the HTML from a given URL or set of URLs that I hardcode in it. I have a JSP that I was given that already does this. I was told that I need to put it in a normal Java file so I can run it and test it and my code can be put where it belongs by another developer. So far I've worked a lot of the kinks out but I'm a little confused by what I got on another forum. Below is my code:

    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.net.MalformedURLException;
    import java.net.URL;
    import java.net.URLConnection;
    import java.util.Locale;
     
     
    public class htmlOutput {
     
    	/**
    	 * @param args
    	 */
     
     
    	public static void main(String[] args) {
    		pageContext.setAttribute("enBean","en");
     
    		Locale locale = (Locale) session.getAttribute(Globals.LOCALE_KEY);
    		if (locale == null) {
    			locale = new Locale(Constants.LOCALE_EN);
    		}
     
    		// Setting the session attribute indicating entry from index page
    		session.setAttribute(Constants.ENTER_FROM_INDEX, new Boolean(true));
     
    		URL headerURL;
    		URLConnection headerURLConnection;
    		BufferedReader br;
     
    		String inputLine;
     
            try {
                headerURL = new URL("*");
                headerURL = new URL("*");
                headerURL = new URL("*");
                headerURLConnection = headerURL.openConnection();
                br = new BufferedReader(new InputStreamReader(headerURLConnection.getInputStream()));
     
                while ((inputLine = br.readLine()) != null) {
                    System.out.println(inputLine);
                }
     
            } catch (MalformedURLException me) {
                System.out.println("MalformedURLException: " + me);
            } catch (IOException ioe) {
                System.out.println("IOException: " + ioe);
            }finally{
            	br.close();
            }
     
            //Process proc = Runtime.getRuntime().exec("./html_compare.ksh");
     
    	}
     
    }
    It is giving me some errors on pageContext, session, Globals, Constants, and out saying they cannot be resolved or cannot be resolved to a variable and I was told by extracting a delegate class to do the work you avoid pageContext and session and for the most part you avoid Globals and Constants. They said I would need to create some new methods for this but didn't give much more information to which I asked:

    I know I'll need multiple methods. I guess the thing that confuses me are things like:

    pageContext.setAttribute("enBean","en");

    Should pageContext be a method and therefore this would be an object of that method?

    Also:
    Locale locale = (Locale) session.getAttribute(Globals.LOCALE_KEY);
    if (locale == null) {
    locale = new Locale(Constants.LOCALE_EN);
    For this what should session, Globals and Constants be? Should they also be separate methods and therefore I'm calling objects?

    Any help here would be greatly appreciated.
