What is GlassFish ?

• A Community> Users, Partners, Testers, Developers, ...> Started in 2005 on java.net

• Application Server> Enterprise Quality and Open Source (CDDL & GPL v2)> Java EE 5 / 6 Reference Implementation> Full Commercial Support from Sun

http://glassfish.org


State of GlassFish

• GlassFish v2> Java EE 5 Reference Implementation> Clustering, Load-balancing, High Availability> Web-based / CLI Administration Console> .NET Web services interoperability> Current release: GlassFish v2.x

• GlassFish v3> Java EE 6 Reference Implementation> Modular (OSGi), Embeddable, Extensible> Java EE, Rails, Grails, Django, ...> Going final this year

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)

{...

}

Java EE 6 Wizards


Java Persistence API

• Java EE specification that defines Object to Relational Mapping

• Annotations to persist POJOs• JPQL to query database objects• Requires a Persistence Provider and a Database

> Common Persistence Providers: TopLinkEssentials, EclipseLink, ...

> Common Databases: Oracle, MySQL, ...


JPA Sample@Entity class Employee {

@Id private int id;

private String firstName; private String lastName;

pubic Employee (int id, String firstName, String lastName) {

...

}

public String getFullName(){return firstName + lastName;

}

...

}

JPA Wizards


RESTful Web Services

• JAX-RS: Java API for RESTful Web Services• Annotation-based server-side API• HTTP-centric• Jersey: Implementation of JAX-RS

> Also provides client-side API


JAX-RS Sample@Path("widgets/{id}")@Produces("application/widgets+xml")@Consumes("application/widgets+xml")public class WidgetResource {

private Widget w;

public WidgetResource(@PathParam("id") String id) { this.w = locateRecord(id); }

@GET Widget getWidget() { return w; }

@PUT Widget updateWidget(Widget update) { w = processUpdate(update); return w; }

}

Light-weight & On-demand Monitoring

• Event-driven light-weight and non-intrusive monitoring

• Modules provide domain specific probes (monitoring events)> EJB, Web, Connector, JPA, Jersey, Orb, Ruby

• End-to-end monitoring on Solaris using DTrace

• 3rd party scripting clients> JavaScript to begin with

REST Interface

• REST interface to management and monitoring data> Configuration data, Commands invocation (start/stop

instance, deploy, undeploy, ...), CRUD resources (JMS, JDBC, ...)

> localhost:4848/management/domain> localhost:4848/monitoring/domain

• GET, POST, DELETE methods• XML, JSON, HTML reps
