jWebApp is a trouble free full stack MVC web application framework that truly removes the complexities of web development and its configuration.  jWebApp is so simple, it can actually be learned in a matter of minutes.

 

jWebApp is literally this simple:

 

public class JWebAppExample extends RequestHandler

  {

    DatabaseManager jpersistdb = AppUtils.getDatabaseManager();

 

    public String processGetCustomer(HttpServletRequest request)

      {

        request.setAttribute("customer", jpersistdb.loadObject(Customer.class,

"where :customerId like ?",

request.getParameter(“customerId”)));

       

        return "/WEB-INF/customer.jsp";

      }

 

    public String validateNewCustomer(ServerInterface serverInterface)

      {

        ... // trivial validation stuff

        if (errors.length() > 0) return “/WEB-INF/newCustomer.jsp”

        else return SUCCESS;

      }

 

    public String processNewCustomer(ServerInterface serverInterface)

      {

        Customer customer = new Customer();

 

        serverInterface.fillObjectFromRequest(customer);

 

        jpersistdb.saveObject(customer);

 

        serverInterface.setAttribute(“customer”, customer);

        serverInterface.setAttribute(“customerSaved”, “Customer Saved”);

 

        return "/WEB-INF/customer.jsp";

      }

  }

 

JSP generation:

 

<div align="center">

    <h2>jWebApp Example.</h2>

    <b>${customerSaved}</b>

    <p>CustomerId: ${customer.customerId}

    <p>First Name: ${customer.firstName}

    <p>Last Name: ${customer.lastName}

    ...

</div>

 

and calling:

 

http://host/context/jWebAppExample/getCustomer?customerId=value

 

or post a form with:

 

http://host/context/jWebAppExample/newCustomer

 

Using the above given URLs, jWebApp automatically finds the supporting class, instantiates it, and executes the supporting method.  jWebApp does not require any configuration or annotation, so the above is actually all you have to do.

 

jWebApp provides support for all of the features you expect, but does not need additional tag libraries or extensive APIs to implement them, what you already know is all you will need.  With jWebApp, you can use any model/business layer technologies, any database-access technologies, any web-authoring technologies, and plain old HTML and HTML forms.
