Design:

This is web application is built using MVC (Model view controller architecture). View is

used to display the output in a web page, controller is responsible for handling the input from

the used entered in the web page and store in the database. Used Eclipse tool to develop the

code and to run the web application installed Apache tomcat server.

EmployeeController.java is servlet, that will check for what view are you going to enter. That is,

if you are in submit mode, the servlet wil go submit log and insert the data into database and if

you are in delete mode, the servlet will perform delete action.

Following is the structure of the folders and packages in eclipse:

Implementation:

Starting point application starts at web.xml page, then it will go index.jsp page which

will redirect to EmployeeController.java file, there we have a logic to check initially which page

to display. Here we are displaying List of employees and list of works on page.

Screenshot:

The List of employees and works_on list will be displayed as shown below:

The above screenshot has a company logo, and list of employee, and below that table you can

see an add employee button, if you click on the add employee button, it will redirect to a add

employee page.

Add user logic is written above. Where wea re calling a procedure

‘dbo.SP_Insert_NewEmployee’

And also For each and every row there is column called action, it has a delete button. When you

click on delete button it will redirect to delete page where it will delete first

Above method, first we are deleting the data from works_on table based on ssn, and then

deleting the data from the employee table which is based on ssn.

Add New Employee Form will be as shown below

When you click the submit button, it will call the insert method which internally calls a stored

procedure.

Following is the stored procedure that is responsible to insert the employee details

The stored procedure is shown in folder

Showing the output screenshot after inserting of the employee into the database is done:

The updated record is shown in employee table as shown below

The updated record is shown in works_on table as shown below:
