newbie question on methods in classes

hi all

I'm an absolute newbie to Java, but have programmed in Visual Basic for the last

5 years. I successfully created a Java servlet in Forte for Java Community Edition 3.0,

and viewed it successfully in a web browser.

Now, I'd like to add some more info to the webpage that is generated by the servlet.

The servlet uses a method called processRequest, as shown below:

protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, java.io.IOException {

        String temp = null;
        response.setContentType("text/html");
        java.io.PrintWriter out = response.getWriter();

        //* output your page here
        out.println("<html>");
        out.println("<head>");

Now, I'd like to add some more output from info read from a database. (I've got that part

working too, thanks to some code I found elsewhere on the 'net.)

Basically, what I'd like to say is:

out.println(LoginForm());

where LoginForm is a method that returns a string containing all the HTML for the login page.

I can't use JSP's because all the content is stored in the database, and the DB has its own interface

for managing the content in it, including the Login form.

The error I receive from the compiler is:

mywebapp.java [62:1] cannot resolve symbol
symbol : method LoginForm ()
location: class mywebapp
out.println(LoginForm());

^
1 error
Errors compiling mywebapp.

The LoginForm class is:

import java.sql.*;
import java.lang.String.*;

public class LoginForm {

    String temp = null;

    /** Creates new LoginForm **/
    public String LoginForm() {

        // open the database here and send the login form
        try

        {

            // Register JDBC/ODBC Driver in jdbc DriverManager
            // On some platforms with some java VMs, newInstance() is necessary...
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();

(other code excluded....)

return temp; /* returns the content of the login form as grabbed from the DB */

(other code excluded....)

Can someone point me in the right direction? Why is LoginForm an unresolved symbol?

I'd rather not put the LoginForm method in the mywebapp servlet, as I supposed that

having multiple classes made things a bit easier for maintenance? ie instead of looking

through all the code in mywebapp if there is a problem with the loginform, I can go straight

to the LoginForm class (ie: LoginForm.java) and edit just that file.

Thanks for taking the time to help.....
