This is my jsp page.. I am getting the method from modal class and iterating the table..

HTML

<html>
<body>
<%ArrayList<Employee> empList=new ArrayList<Employee>();
ModalClass emp=new ModalClass();

empList = emp.getEmployess();

<!-- With this list i will iterate my table -->

</body>
</html>

And this is my modal class(java), is used to fetch the values from db.

Java

public Class ModalClass {

public ArrayList<Employee> getEmployess(){
    //In this method i am fetching the db values and storing into the List and returning the list...
 

return list;
}

I hope the reader can understand my coding,now my question is Wheather my code follows MVC pattern..

Thanks in advance...

I am not too sure whether your code follows MVC pattern

In MVC

1.Model : Model is where the data classes, looks you have done this using the class "ModalClass"

2 View : This should be almost pure HTML and should not have any data access class initiations / methods and you are defeating this by using the following

XML

<%ArrayList<Employee> empList=new ArrayList<Employee>();
ModalClass emp=new ModalClass();

empList = emp.getEmployess();

<!-- With this list i will iterate my table

3. Controller : This is where you will have any data access class initiations / methods and its missing in your case.

I think you code does not satisfy the MVC pattern

Thanks dude, but i have one doubt i have to call the method when jsp page loads, so i need to use java code to call that method..is there any other way to call the method in mvc pattern?

Hi, I am not sure about how the java side works.

In Microsoft .net side, "Controller" is responsible for calling the methods (not the html layer) and it will pass the result to the view (HTML) and the view will render the data.

In other words, the so called "method callings" are separated and put under controller and from controller the result (object) is passed to the view

Your code

<%ArrayList<employee> empList=new ArrayList<employee>();
ModalClass emp=new ModalClass();

empList = emp.getEmployess();

<!-- With this list i will iterate my table

should have been under the controller
