Tools Coverage for the Java EE 6 Platform
Ludovic Champenois – GlassFish team, Eclipse and NetBeans

4. AGENDA
• Java EE 6: Overview And Status
• Tools Support and Demos
– In NetBeans, Eclipse, IntelliJ
• Server runtime, JPA, RestFul Services Jax-RS
• Maybe JSF2.0, CDI
• Q&A
4

5. Java EE 6
• What's New?
– Lots of improvements to existing EE 5 APIs
– Several New APIs
– Web Profile
– Pluggability/Extensibility
– Dependency Injection
• A Major new release for Java Enterprise Applications
– Easier, Smaller, Extensible
– GlassFish 3 is the Reference Implementation
• and a production quality product...
– GlassFish 3.1 is adding Clustering support

6. Java EE 6: Fast Uptake within Open
Source and Commercial Community

8. Java EE 6: Impact on Tools
• New APIs are easy to expose:
– Libraries in project path. More and more on Maven (EE 6 APIs in
Maven)
– Automatic Code completion
– JavaDoc: Some IDEs...
• New Concepts:
– JSF 2.0: face-config obsolete, ManagedBeans obsolete (->CDI)
– JAX-RS
– No Web.xml, more annotations
• New Packaging:
– EBJ Inside Web Application Projects!
– Web Profile versus Full Profile
– But Endorsed APIs (Add Maven complexity)
8

9. Java EE 6 : Impact on Tools
• Alignment of Platform changes and the IDEs
– NetBeans 6.8: same day as Java EE 6 GlassFish (Dec 2009)
• Almost everything but CDI and advanced JF 2.0 (fixed in 6.9)
– IntelliJ: Same week as Java EE 6
• GlassFish Runtime target Supported in Dec 2009
• Eclipse:
– Java EE 6 support June 2010
– But GlassFish Plugin with EE 6 support before...
– Oracle Enterprise Pack for Eclipse
• Maven: All IDEs support it
– Project portability across IDEs and CLI
– Stripped Java EE API JARs in the repo

10. Oracle Involvement In Java EE 6 And Tools
• Oracle is the main driver of the GlassFish Community
– The Java EE 6 Reference Implementation
– Production Ready (Clustering, HA,...)
• Oracle is the main driver of the NetBeans Community
– Tight coupling with Java SE and EE changes.
• Oracle has many Eclipse Committers
– In JPA: EclipseLink Runtime and Dali Tooling
– In Core Java EE tooling
– In JSF: Most JSF WTP Eclipse tooling done by Oracle folks
• Jboss Tools has their own JSF tooling
– GlassFish and Weblogic support via OEPE

11. Java EE 6: Oracle Gives Developer Choices
Oracle Enterprise Pack for Eclipse NetBeans 6.9.1 and Coming 7
Target WebLogic and GlassFish 3 Bundled with GlassFish 3 or 3.1
IntelliJ IDEA has great Java EE 6 Support
11

12. Java EE 6 Integration in IDEs
• Looking for:
– Bundle or not
– Easy registration or download of the GF runtime
– Easy configuration
– Start, Stop, Debug, Profile
– Admin features?
• Deploy, Undeploy, Remote Servers?
• EE resources registration
• Log File
– JavaDoc, Help menus
– Good Default Values
– Respect for Standard or promotion of private APIs?
12

13. Java EE 6: Working with a GlassFish
Server in the Tools:
NetBeans, Eclipse and IntelliJ
13

14. Java EE 6 Working with Databases
• Via JPA 2.0
• Out of the Box, GlassFish 3 bundles Derby DB
– Registered in NetBeans and Eclipse
• All IDEs can register DB Resources and Introspect
• All IDEs can Generate JPA From DB
• All IDEs give decent Mapping Tooling
• Can Start/Stop Dbs only in NetBeans!
• NetBeans has extra Wizards to Generate CRUD JSF2
• NetBeans has better Default in Persistence.xml
• IntelliJ has some ER/UML view and JP/QL Support
14

15. JAX-RS
• REST made easy
• Java Annotation Based REST Resource Creation
– Identity of Resources
• http://example.com/customers/petrobras
– Self-Descriptive Resources
• Bookmark-able, human friendly
– Navigation between Resources
• http://example.com/customers/petrobras/orders/2
– Representation choices
• XML, JSON, HTML, Application-Specific
• CRUD Operations:
– GET, DELETE, POST, PUT
15

16. Java EE 6 JAX-RS and Web Services
• Simple REST Resources Creation/Configuration:
– In NetBeans and Eclipse (via GlassFish plugin)
• Advanced Wizards Generating
– Only in NetBeans
• Resources from Database
• Resources from Entity Classes
• Resources from Patterns
• REST WS Tester:
– NetBeans and IntelliJ
• JAX-WS:
– Service Creation, Testing Web Services:
• Clear Advantage NetBeans
– Eclipse is Axis based
16

17. JSF 2.0
• Facelets is the foundation
– XHTML and tags
– Templating
• ui:include, ui:composition, ui:define,...
– Composite Components
• Reusable
• Turn page markup into a JSF UI component
• Managed Beans
– Annotations (faces-config is optional)
– JSF APIs or
– CDI APIs (Preferred)
• CDI support (@Named, @Inject, @SessionScoped,...)
17

18. JSF 2.0 Tooling
• NetBeans and IntelliJ are best
– XHTML/Facelet Editor
• Code Completion, Beans navigation
– NetBeans 6.10 bundles Primefaces components
– JPA to JSF 2.0 Wizards (only NetBeans)
>
– NetBeans Create Composite Components automatically
• Eclipse is lacking the new features with CDI and
annotations
– No code completion for CDI in Eclipse
18

19. Java EE 6 CDI Tooling
• Should be easy:
– Enable CDI in a Module: Create an empty beans.xml file
– Use @Inject, @Named, @SessionScoped, @ApplicationScoped
• Only Need EE 6 APIs in Path and Code Completion.
• JavaDoc a Goody
• But in EL (Facelets and JSP): Code Completion?
– Not for Eclipse at this moment. Only in NetBeans and IntelliJ
