Okay, seems that you are newbie,

hey buddy you've already done the code for retrieving the data from database
checkout EmployeeDAO.java

Click: JSP Database Connectivity Code

hope it works
Apr 13 '09 #2
Yes I know the code to retrieve is there in that DAO class..
But how do I display it ?? I mean I have used the <bean:write > tag in my JSP file but its not displaying any value.

How can I write the code for DB connection and data retrieval again in my JSP when I have already made a separate class for that purpose i.e EmployeeDAO.java

Why is it not getting displayed ? Is there some problem with <bean:write > tag ?

Also when I hover mouse on <bean:write> tag
it says "unknown tag bean:write"

Whats wrong with it ?

At the top of the jsp page, just above the <html> tag write following lines:-

  1. <%@ page language="java" %>
  2. <%@ taglib uri="/WEB-INF/struts-bean.tld"   prefix="bean" %>

Apr 13 '09 #4
I just included the line below in my JSP file. It doesn't show the error "unknown tag bean:write" anymore.

<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>

Now that I am running my file it says :-
I know the error has to do something with name and property attributes I have given in the <bean:write> tag .. I am just not able to figure out. Please help me guys.

Oh I just did that only..
Now its giving another error :(

I am sure it has something to do with the name and property attribute in the <bean:write> tag in my JSP file.

you have to define employeeDetailForm on the jsp page
Apr 13 '09 #7
u mean i need to import that employeeDetailsForm.java file in my JSP file or what ??

What do u mean by define ?
create object of it in JSP file ??

Seriously my mind has stopped working ...
I am struggling with this code for like 6-7 hours now and I need to complete it today only
Apr 13 '09 #8
ok in my DAO class I have retrieved all fields from the emp_mstr table in the getRecords() method and returning the Employee object ..

Now how do I use this object in my JSP page to display the values of all the fields that it contains ??

god I am sooo lost :(
