AGENDA

> Java EE 6> Tools Support

– IntelliJ– Eclipse– NetBeans

> Demos> Q&A

4

Java EE 6

> A Major new release for Java Enterprise Applications– Easier, Smaller, Extensible– GlassFish 3 is the Reference Implementation (and a quality product...) – GlassFish 3.1 is adding Clustering support

> Update Components– EJB 3.1 JPA 2.0 Servlet 3.0 JSF 2.0 Interceptors 1.1 – JAX-WS 2.2 JSR-109 1.3 JSP 2.2– EL 2.2 JSR-250 1.1 JACC 1.5 Connectors 1.6

> New Components– JAX-RS 1.1 CDI 1.0 Bean Validation 1.0 DI 1.0 – Managed Beans 1.0 JASPIC 1.1

5

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

6

Java EE 6 : Impact on Tools> Alignment of Platform changes and the IDEs

– Emacs (James Gosling 81), vi (Bill Joy 76): First IDES choice Java EE 6 compliant

– 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:

First IDE Java EE 6 support 6 months later But GlassFish Plugin with EE 6 support before...

Java EE 6 and IntelliJ– Code Assistance

code completion, javadoc, navigation, refactoring

– Code Generation Easy creation of new classes, interfaces, packages, and files Quick generation of standard methods Quick Override/Implement methods Generating "delegation" methods Surrounding of selected code fragment with try/catch, if/else, synchronized,... Generating methods, constants, parameters from unknown usages

– Java EE JP Editor, TagLib support,JSP Refactoring, Ajax, JSF: 2.0 features: Custom Composite Components, Resource Loading

(@ResourceDependency, <h:outputScript>, <h:outputStylesheet>) Managed beans and components annotations (@ManagedBean,

@FacesComponent, @FacesRenderer, etc.) including code completion, usage search and basic refactoring

CDI support (@Named, @Inject : dependencies diagrams, rename, better navigation ...

8

Java EE 6 and IntelliJ– JSF-aware coding assistance with code completion and formatting– Graphical face-config editing– EJB 3.1, including support for EJB 3.1 @Singleton Session Bean– JPA 2.0 Support

JPA 2.0 @ElementCollection attribute type, plus freshly allowed attribute types in embeddable objects (@OneToOne, @Embedded, etc.)

JPA 1.0/2.0 with Hibernate provider will not throw false-positive warnings about certain JPA specification violations that occur because of differences in JPA and Hibernate.

JPQ QL support Generate from DB

IntelliJ: What could be improved> Registering a new GlassFish Java EE 6 runtime> API libraries customization

– Download from the Web why?– Using the ones provided by the GlassFish Runtime

> Lack of complete Java EE 6 Javadoc code completion> Some EE 6 Specific wizards missing

– Cannot create a servlet without web.xml (even if servlet 3.0 is selected)– EJB inside Web App, JAX-RS Resources, Bean Validation...– Easy to create once you know the corresponding annotations

10

Eclipse Helios (3.6)> Eclipse 3.6 will introduce Java EE 6 artifacts (June 2010)

– EJB 3.1 (Inside Web App, no interface needed)– Web.xml optional– Servlet, Filter, Listener annotated, Facelets XHTML– JPA 2.0 is excellent (EclipseLink used in WebLogic and GlassFish EE 6)– Java EE 6 XML schemas

> But not complete support– No Jax-RS wizards, No Beans Validation– JSF 2.0 lacking code completion for annotated artifacts– Still very faces-config driven– No CDI support at all: you need to discover it

> Still Too JSRs centric as Opposed to Java EE 6 centric> More in December 2010 Update Release (I hope...)

11

Eclipse and Oracle Involvement> Oracle has many Eclipse Committers> JPA:

– EclipseLink is developed in Eclipse– JPA Dali Tools: up to date, and comprehensive

> Core Java EE tooling– Facet framework in Eclipse done by Oracle folks

> JSF – Most JSF Eclipse tooling done by Oracle folks– Jboss Tools has their own JSF tooling

> Jax-RS, Jax-WS, EJB, CDI, Bean Validation: – Need more involvement with the Eclipse community

12

Oracle OEPE Pack for Eclipse> Zip bundle or update center> Target WebLogic Server and Glassfish via Eclipse Plugin

– For Java EE 6: Extra wizards for JAX RS, EJB Singleton, Java EE 6 Javadoc Code Completion Tight integration with GlassFish Java EE 6: Start, Stop, Debug, Profile (TPTP) Fast Deploy On Save Session Preservation at redeployment time Exploded directory deployment

> Better JSF/JSP tooling > Facelet XHTML support> SpringSource Tooling > JAX-WS wizards (only work with WebLogic target)> Free: Close source and close license

13

NetBeans> Close relationship with the Java EE 6 Platform development

– NetBeans 6.8 shipped same day, with GlassFish bundled in it> Strong Java EE 6 Development

– Web Profile, Full Profile– Many EE 6 Wizards– End to End Wizards (DB to JPA, JPA to REST, JPA to JSF 2.0...)– Maven Java EE 6 targets

> Tight Integration with the GlassFish Runtime– Bundled– Deploy On Save, Session Preservation– Resources definitions and deployment

> NetBeans 6.9 (Soon) adds CDI and better JSF 2.0 support
