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
Using Eclipse for Java EE 6 development for GlassFish Slide 3

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
Servlet in Java EE 5: Create two source
<!--Deployment descriptor /* Code in Java Class */
files
web.xml -->
<web-app> package com.foo;
<servlet> public class MyServlet
<servlet-name>MyServlet extends HttpServlet {
</servlet-name> public void
<servlet-class> doGet(HttpServletRequest
com.foo.MyServlet
</servlet-class> req,HttpServletResponse res)
</servlet> {
<servlet-mapping>
<servlet-name>MyServlet ...
</servlet-name>
<url-pattern>/myApp/* }
</url-pattern>
</servlet-mapping>
... ...
</web-app>
}

EoD Example - Servlets
Servlet 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)
{
...
}
