Java Persistence API
• Java specification that defines Object to
Relational Mapping in Java EE 5
• Annotations to persist POJOs
• JPQL to query objects from the database
>MySQL-specific query statements (LIMIT)
• Requires a Persistence Provider and a
Database
>Common Persistence Providers:
TopLinkEssentials, EclipseLink JPA, ...
>Common Databases: MySQL, Oracle, ...

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;
}
...
}


Demo: CRUD operations using
NetBeans, JPA, and
GlassFish

RESTful Web Services

• JAX-RS: Java API for RESTful Web services
• Annotation-based server-side API
• HTTP Centric
• Jersey: Reference Implementation of JAX-RS
• Also provides client-side API
• jersey.dev.java.net


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;
}
}


GET /NetBeans/6.5


Demo: Publish your MySQL Table
as a RESTful Web service

Rails on GlassFish

• Native Deployment, no packaging required
> GlassFish v3
> Capistrano recipes available
> Server runtime available as Gem
• WAR deployment using Warbler
> GlassFish v2 and v3
• JRuby/Rails (Groovy/Grails, Django/Jython)
modules at Update Center
• Commercially supported by Sun

Tooling
• NetBeans support
> Develop, deploy debug


Demo: Develop, Deploy, and Debug
Rails application using
NetBeans and GlassFish

GlassFish v3 Monitoring
• Event-driven light-weight and non-intrusive monitoring
• Modules provide domain specific probes (monitoring
events)
> EJB, Web, Connector, JPA, Jersey, Orb
• Monitoring data gathered on demand
• End-to-end monitoring on Solaris platforms using DTrace
• Equivalent functionality for GlassFish on other platforms
(including Solaris) using scripting languages
> JavaScript to start with


Demo: End-to-End Application
Tracing using NetBeans, GlassFish,
MySQL, OpenSolaris, DTrace
