Problem accessing a bean from a JSP

[D Prasad]

Alright, I have tried a different design based on a template. The controller servlet dispenses the JSPs and the dataBean stores values into the database.
I haven't gotten to the display servet yet, I just want to get the values into the database to start wtih. Here is the error I get trying to compile addPage.jsp
showPage$jsp.java [70:1] cannot resolve symbol
symbol : class dataBean
location: package burnaby
com.brainysoftware.burnaby.dataBean dbBean = null;
^
showPage$jsp.java [73:1] cannot resolve symbol

package com.brainysoftware.burnaby;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import com.brainysoftware.burnaby.DbBean;
public class ControllerServlet extends HttpServlet {
  /**Initialize global variables*/
  public void init(ServletConfig config) throws ServletException {
    System.out.println("initializing controller servlet.");
    ServletContext context = config.getServletContext();
    context.setAttribute("base", config.getInitParameter("base"));
    context.setAttribute("imageUrl", config.getInitParameter("imageUrl"));
    // instantiating the DbBean
    DbBean dbBean = new DbBean();
    // initialize the DbBean's fields
    dbBean.setDbUrl(config.getInitParameter("dbUrl"));
    dbBean.setDbUserName(config.getInitParameter("dbUserName"));
    dbBean.setDbPassword(config.getInitParameter("dbPassword"));
    // put the bean in the servlet context 
    // the bean will be accessed from JSP pages
    context.setAttribute("dbBean", dbBean);    
    try {
      // loading the database JDBC driver
      Class.forName(config.getInitParameter("jdbcDriver"));
      System.out.println(config.getInitParameter("jdbcDriver"));
    }
    catch (ClassNotFoundException e) {
      System.out.println(e.toString());
    }

NOTE: THE SHOWPAGE.JSP FILENAME IS MISLEADING, SORRY FOR THE CONFUSION IT IS ACTUALLY FOR PUTTING VALUES IN THE DATABASE

wow, that's a lot of code for a post!
-sorry if I missed it, but, where's the constructor for your bean?

[Malhar Barai]

hi...
Shouldn't you be importing the package in your JSP files...
<%@ page import="java.util.*, com.brainysoftware.burnaby.*" %> or
<%@ page import="java.util.*" %>
<%@ page import="com.brainysoftware.burnaby.*" %>

Alright, I tried to import the package, both by combining it with the import of the sql package, also importing it on its own line..still the same problem. This is probably a really simple thing I am overlooking...GRRRRRRRRRRRRRRRR!

[Malhar Barai]

Hi..
No constructor in dataBean.java...!!!??

public dataBean() {}

Also in ControllerServlet

import com.brainysoftware.burnaby.DbBean

should be

import com.brainysoftware.burnaby.dataBean
