Java Research License (JRL)

For academics, researchers,the curious, contributors

Greatly simplified:> Simple 2-pager, click-through> Allows very broad use for research

> Residual knowledge does not preventnon-Sun work

> No copyright or patent rights> No compatibility, TCK requirements

No commercial use, redistribution

Contribution agreement for givingcode back must be compatible

JCP remains steward of Java APIs

Enterprise customers can deploytheir own bugfixes> Sun can enforce compatibility but doesn't

require running TCK

> Honor system - At the customers own risk> Some guidelines: no API changes

For internal use> Includes software powering public websites> Excludes external distribution

Allows sharing of bugfixes> Encourages but doesn't require returning fixes

Machine Setup: Linux

Linux

Verifying that your release of Linux can successfully

build might take some time due to compatibilityproblems with the C/C++ runtime library, i.e. It'snot obvious which Linux's are compatible.

> X86 Linux RedHat A.S. 2.1 Update 1> Motif needed

:

41

Machine Setup: Windows

Windows (most complicated setup)> Compilers

>Visual Studio .NET Professional 2003

Contains newer Platform SDK

Contains newer unicows.lib

> DirectX SDK 9.0 (or 7.0 but hard to find)

> MKS or CYGWIN

> UNICOWS.DLL

:

47

Common Build Procedures

Control Builds> Examples, 'cd control/make' and:

>Builds complete product:gnumake SKIP_FASTDEBUG_BUILD=true scsl

>Could Skip hotspot build (importing it in from a previousbuild)

gnumake BUILD_HOTSPOT=false scsl

:

48

Common Build Problems

Missing files> Missing font files (added sanity check for this)

Native compiler unknowns

Specific OS version issues (SP's patches)

Where it's built determines where it can run

Clean/Clobber build issues(INCREMENTAL_BUILD=true)


10/04/2005


17/42


:

49

Issues

Machine setup needs simplification, Windows inparticular

Stick with free or freely available build tools Build variations need to be allowed and

documented (ANT, subset builds, etc.)

Relax sanity error checks where we can

Add sanity checks as encountered

The J2EETMChallenge

J2EE is enormously powerful> The industry standard for robust enterprise apps

But that power sometimes gets in the way> Too difficult to get started> Even simple apps need boring boilerplate

Can we keep the power, but make typicaldevelopment tasks simpler?

YES : and that is the focus of Java EE 5!

:

71

Ease of DevelopmentImprovements in JavaTM EE 5

POJO-based programming (Plain Old Java Object)> More freedom, fewer requirements

Extensive use of annotations> Reduced need for deployment descriptors

Resource Injection> Inversion of control

New APIs and frameworks

:

72

JavaTM EE 5 Major Features

Simplified web services support

More web service standards support

Greatly simplified EJBTM development

New persistence API

Easy web applications with JavaServerTM Faces

New persistence API (JSR-220)

JAXB (JSR-222)

JAX-WS (JSR-224)

Common Annotations (JSR-250)

:

74

Primary Goal of EJB 3.0

Ease of Development!

:

75

EJB 2.1

Very powerful, but complex to use> Too many classes, interfaces> Java Naming and Directory Interface

(JNDI) API lookups> javax.ejb interfaces> Awkward programming model> Deployment descriptors> Entity bean anti-patterns> ...


10/04/2005


26/42


:

76

Ease of Development Features inEJB 3.0

? Fewer classes and interfaces

? Dependency injection? Simple lookups

? No required container interfaces

? No required deployment descriptor

? Simplified persistence

? Object/relational mapping

:

77

EJB 3.0 Example

// Same example, EJB 3.0

@Stateless public class PayrollBean

implements Payroll {

@Resource DataSource empDB;

public void setBenefitsDeduction (int empId, doublededuction) {

...

Connection conn = empDB.getConnection();

...

}

...

}

:

78

Dependency Injection

Resources a bean depends upon are injected whenbean instance is constructed

References to:> EJBContext> DataSources> UserTransaction> Environment entries> EntityManager> TimerService> Other EJB beans> ...


10/04/2005


27/42


:

79

Dependency Injection

Annotations> @EJB

>References to EJB business interfaces

>References to Home interfaces (when accessingEJB 2.1 components)

> @Resource>Almost everything else

> Number of annotations is simplified from EJB 3 specificationearly draft

Injection can also be specified using deploymentdescriptor elements

:

80

Simplified Client View

Session beans have plain Java language businessinterface> No more EJB(Local)Home interface> No more EJB(Local)Object interface

Bean class implements interface> Looks like normal Java class to bean developer

Looks like normal Java language interfaceto client (POJI)

:

81

EJB 3.0 Client Example

// EJB 3.0 client view

@EJB ShoppingCart myCart;

...

Collection widgets = myCart.startToShop(widgets);

...

EJB 3.0

Persistence

:

83

Persistence Goals of EJB 3.0

Simplify entity bean programming model

Support for light-weight domain modeling,including:> Inheritance and polymorphism

Complete query capabilities

Support for object/relational mappingspecification

Make entity instances usable outside the EJB

container> Remove need for DTOs and similar antipatterns

:

84

Persistence Model in EJB 3.0

Entities are simple Java classes> Concrete classessupport use of new> Getter/setter property methods or persistent

instance variables> No required bean interfaces> No required callback interfaces

Usable as detached objects in otherapplication tiers> No more need for DTOs (Data Transfer Objects)


10/04/2005


29/42


:

85

EntityManager

EntityManager serves as untyped home

for entity operations Methods for lifecycle operations> Persist, remove, merge, flush, refresh, etc.

Similar in functionality to Hibernate Session,JDO PersistenceManager, etc.

:

86

Persistence Focus: O/R Mapping

Ease-of-use facility for Java developers mappingdomain object model to a relational database

Developer is aware of mapping betweenDB schema and domain object model> Developer is in control of mapping> Developer can rely on mapping and its semantics

Mappings may be expressed using metadataannotations or XML>

Default mappings provided

87

EJB 3.0

Interoperability with EJB 2.1


10/04/2005


30/42


:

88

EJB 3.0/2.x TechnologyInteroperability and Migration

Applications written to EJB 2.1 specification andearlier work unchanged in EJB 3.0 containers

Migration path to EJB 3.0 APIs> New applications can be clients of older beans> Older clients can be clients of new EJB 3.0

components>Without change to preexisting client view

:

89

Web Services

JAX-WS and JAXB Integration

:

90

Java Support for Web Services

JAX-RPC 2.0 renamed to JAX-WS 2.0 (Java APIfor XML Web Services)

Implements new WS stack> JAX-WS 2.0 and JAXB 2.0> Designed for growth (JAX-WSA, others)

Heavy use of annotations> Ease-of-development> Portability

Supports Fast Infoset> Better Performance


10/04/2005


31/42


:

91

JAX-WS and JAXB Integration

JAX-WS delegates all data binding to JAXB

Development time> JAXB generates Java types from a WSDLs schemas> JAXB generates the WSDLs schema from Java types

Runtime> JAX-WS un/marshalls the message (soap:envelope)> JAXB un/marshalls the payload (soap:body child,

soap:header and soapfault elements)

JAXB 2.0 Is Now Bi-Directional

1.0: Schema Java only

> JAXB is for compiling schema> Dont touch the generated code

2.0: Java XML + schema compiler> JAXB is about persisting POJOs to XML> Annotations for controlling XML representation> Modify the generated code to suit your taste

Limited XML Schema support

Little Control of Mapping Java and WSDL/XML Schema

Large non-portable applications

Large runtime

Web Service development is too complex

Servlet container is required

JAX-RPC 1.1 Issues> Defines its own data binding rules

> Only a portion of XML Schema supported> javax.xml.soap.SOAPElement (DOM)> No control of the generated Java SEI

JAX-WS 2.0> Uses JAXB 2.0 for data binding (100% XML Schema)> Very few DOM-like mappings> Customizations to control the generated SEI

Customizations in WSDL/XMLSchema to Java Mapping

JAXB customizations

> XML Schema to Java

JAX-WS customizations> Similar to JAXB customizations> WSDL to Java

Can live> In-lined in the WSDL as WSDL extension> As external file (pass to JAX-WS tools)

Preview: Java Technology,Annotations, WSDL

Java class is annotated with @WebService> Becomeswsdl:port-typeelement in the WSDL world

Java Methods are annotated with @WebMethod> Becomes awsdl:operation element in the WSDL world

Java Methods parameters mapping to XML is nowhandled by JAXB> wsdl:message part element types are now defined in

aseparateschemafile imported by the wsdl
