interaction between .Java and .VM

Hello,


I would like to generate a dynamic form ( from a text file. 1 line <=> 1 input type text )
- i read a text file
- i generate the html code to create the form
- i use HttpServletResponse to send this code to the user screen

but i don't know how to access to the file.java from my Menu.vm   ?
where do i put the file.java ?? into the "actions" directory or into the "screens" directory ?

i'm using Turbine and Velocity under Linux RedHat 7.3

here is my Menu.vm :

<font face="$ui.sansSerifFonts">
<a href="$link.setPage("Insert.vm")">Insert Entry</a>
<p>
<a href="$link.setAction("GenerateForm")">Generate Form Dyn</a>
<p>
<b>Flux</b>
<br>
<a href="$link.setPage("user,FluxUserList.vm")">Users</a>
<br>
<a href="$link.setPage("group,FluxGroupList.vm")">Groups</a>
<br>
<a href="$link.setPage("role,FluxRoleList.vm")">Roles</a>
<br>
<a href="$link.setPage("permission,FluxPermissionList.vm")">Permissions</a>
<p>
<a href="$link.setPage("Index.vm")">Home</a>
<p>
<a href="$link.setAction("LogoutUser")">Logout</a>
</font>

here is my GenerateForm.java   :

public class GenerateForm extends HttpServlet {
            public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException            { 
                        res.setContentType("text/html");
                        PrintWriter out = res.getWriter(); 
                        out.println("<HTML>");
                        out.println("<HEAD><TITLE>This is the title</TITLE></HEAD");
                        out.println("<BODY>"); 
                        out.println("<br> <form method='post' enctype='multipart/form-data' action=$link.setPage('Index.vm').setAction('ADDDCM')>");
                        out.println("<input type='submit' value='Send' name='eventSubmit_doAjout'>");
                        FileReader fileReader = null;
                        BufferedReader bufferedReader = null;
                        String initial = null;
                        StringTokenizer st = null;
                        String val1 = null;
                        String val2 = null;
                        String val3 = null; 

                        try {
                           fileReader = new FileReader("./configuration/addMammo.config");
                           bufferedReader = new BufferedReader(fileReader);

                           initial = bufferedReader.readLine();
                            System.out.println(initial);

                            st = new StringTokenizer(initial,"||");
                            val1 = st.nextToken();
                            val2 = st.nextToken();
                            val3 = st.nextToken();
                            out.println(val2 + "<input type='text' value='"+val3+"' name='"+val1+"'> ");
                            out.println("<BR>");
                            initial = bufferedReader.readLine();
                      }
                      catch(FileNotFoundException ignored)
                      {  }
                      catch(IOException ignored) {  }
 
                      while(initial != null) {
                                    try {
                                        st = new StringTokenizer(initial,"||");
                                        val1 = st.nextToken();
                                        val2 = st.nextToken();
                                        val3 = st.nextToken();
                                        out.println(val2+"<input type='text' value='"+val3+"' name='"+val1+"'> ");
                                        out.println("<BR>");
                                        initial = bufferedReader.readLine();
                                    }
                                    catch(FileNotFoundException ignored)            {            }
                                    catch(IOException ignored) {            }
                        }            

// close the file
                        try {
                                    if(bufferedReader != null)
                                    {
                                                out.println("</form>");
                                                bufferedReader.close();
                                    }
                        }
                        catch(IOException ignored) {            }
            }
}

 

where can i find some exemples of "interaction" between .java and .vm ???
if you have some exemples, you can send this to bk394206@skynet.be

thank you...
