Right Sizing

Java EE: Past & Present


Goals for the Java EE 6 Platform

• Right Sizing the Platform> Flexible, lighter weight

• Extensible>Embrace Open Source Frameworks

• Easier to use, develop on>Continue on path set by Java EE 5


Right Sizing the Platform: Profiles• Make platform flexible

> Decouple specifications to allow more combinations

> Expands potential licensee ecosystem> Profiles

>Targeted technology bundles>Defined through the JCP>First profile: Web Profile

– Defined by the Java EE 6 Expert Group


Right Sizing the Platform: Pruning

• Make platform lighter> Makes some technologies optional> Pruned today, means

> optional in the next release> Deleted in the subsequent release

> Pruned Technologies will be marked in the javadocs

> Current pruning list> JAX-RPC, EJB 2.X Entity Beans, JAXR, JSR-88


Extensibility• Embrace open source libraries and

frameworks• Zero-configuration, drag-and-drop for web

frameworks> Servlets, servlet filters, context listeners for a

framework get discovered and registered automatically

• Plugin library jars using web fragments


EoD Example - Servlets

<web-app><servlet> <servlet-name>MyServlet

</servlet-name> <servlet-class> com.foo.MyServlet </servlet-class> </servlet> <servlet-mapping> <servlet-name>MyServlet </servlet-name> <url-pattern>/myApp/* </url-pattern> </servlet-mapping> ... </web-app>

Servlet in Java EE 5: Create two source files /* Code in Java Class */

package com.foo;public class MyServlet extends HttpServlet {public void doGet(HttpServletRequest req,HttpServletResponse res)

{

...

}

...

}


EoD Example - ServletsServlet in Java EE 6: In many cases a single source file

package com.foo;@WebServlet(name=”MyServlet”, urlPattern=”/myApp/*”)public class MyServlet extends HttpServlet {

public void doGet(HttpServletRequest req, HttpServletResponse res)

{...

}
