    Design Patterns web based applications

    Hi,

    I am designing a simple web-based application. I am new to this web-based domain.I needed your advice regarding the design patterns like how responsibility should be distributed among Servlets, criteria to make new Servlet, etc.

    Actually, I have few entities on my home page and corresponding to each one of them we have few options like add, edit and delete. Earlier I was using one Servlet per options like Servlet1 for add entity1, Servlet2 for edit entity1 and so on and in this way we ended up having a large number of servlets.

    Now we are changing our design. My question is how you exactly choose how you choose the responsibility of a servlet. Should we have one Servlet per entity which will process all it's options and forward request to the service layer. Or should we have one servlet for the whole page which will process the whole page request and then forward it to the corresponding service layer? Also, should the request object forwarded to service layer or not.

    Thank You

    "Servlets" implies Java.

    Do you mean the "Workers" in JavaScript?

    Note that Java is not the same language as JavaScript, it just happens to have the name Java in it.
    --> JavaScript Frameworks like JQuery, Angular, Node <--
    ... and please remember to wrap code with forum BBCode tags:-

    [CODE]...[/CODE] [HTML]...[/HTML] [PHP]...[/PHP]

    If you can't think outside the box, you will be trapped forever with no escape...
