• Provide way for customers and users to

leverage public, private, and hybrid clouds

• PaaS support entails evolutionary change

• Next logical step for Java EE

J2EE -> Java EE 6 : The Java EE Platform provides

services

Java EE 7 : The Java EE Platform IS a service

Java EE 7 Focus : Platform as a Service

msg systems ag


[I|P|S]aas - Introduction

msg systems ag


• Define new platform roles to accommodate

PaaS model

• Add metadata

For service provisioning and configuration

For QoS, elasticity

For sharing of applications and resources

For (re)configurability and customization

• Add useful APIs for cloud environment

JAX-RS client API, Caching API, State

Management, JSON,…

• Extend existing APIs with support for

multitenancy

Java EE 7 PaaS Roadmap

msg systems ag


Java EE 7 Roles

msg systems ag

msg systems ag Markus Eisele, Insurance - Strategic IT-Architecture 10

• In the cloud tenant

applications consume

services

• PaaS administrators host,

configure, and manage

application and

infrastructure services

• Existing APIs in Java EE

need to be updated to be

service-enabled and

tenant-aware

Example: pluggable

services, late binding and

tenant id injection

Cloud Services – not just APIs


• Old Java EE Model

Configure Java EE

resources – JDBC, JMS

etc

Deploy Application EAR

• Java EE 7 Model

Provision and deploy

application resources

(e.g. LDAP stripe, data

source instantiation and

connection …)

• Extensible Deployment

Models Supporting

Multiple Frameworks

Spring, Seam, Play …

Existing Java EE Model


Auto-Provision Services from Application Dependencies

• Java EE 7 Model

Provision and deploy

application resources

(e.g. LDAP stripe, data

source instantiation and

connection …)

• Extensible Deployment

Models Supporting

Multiple Frameworks

Spring, Seam, Play …

msg systems ag


• Service Levels

• Minimum and Maximum Instances

• Futures – Self Adjustment, Capacity On Demand

Elasticity

msg systems ag


• Alignment of ManagedBeans across CDI,

EJB, JSF,…

POJO -> ManagedBean -> Enterprise JavaBean

Extension of container-managed transactions

beyond EJB

• Further simplifications for ease-of-

development

JMS 2.0 focus on ease-of-development

Expanded use of dependency injection

Expanded service metadata; improved configuration

• Pruning

EJB CMP and BMP, JAX-RPC, Deployment API

• Update to Web Profile

And … not only clouds:

msg systems ag


Java EE 7 at a Glance


• The main theme is to easily run applications on private or

public clouds

• The platform will define application metadata descriptor to

describe PaaS execution environment such as multi-tenancy,

resources sharing, quality-of-service, and dependencies

between applications

• Embrace latest standards like HTML5, WebSocket, JSON and

have a standards-based API for each one of them

• Remove inconsistencies between Managed Beans, EJB,

Servlets, JSF, CDI, and JAX-RS

• Possible inclusion of JAX-RS 2.0 in the Web Profile, revised

JMS 2.0 API

• Technology Refresh for several existing technologies (more

on this below) and possible inclusion of Concurrency Utilities

for Java EE (JSR 236) and JCache (JSR 107)

• The Expert Groups for most of the JSRs have already been formed

but you can still participate by joining the publicly visible aliases and

reviewing the drafts. All the JSRs following JCP 2.8 are run more

transparently and some of the highlights on that front are:

• Names of the EG members are publicly visible

• EG business reported on publicly readable alias

• Schedule is public, current and updated regularly

• Public can read/write to a wiki to discuss the status so far

• Discussion board on jcp.org

• Public read-only issue tracker
