• 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

[I|P|S]aas - Introduction
msg systems ag
Markus Eisele, Insurance - Strategic IT-Architecture 8
• 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

Markus Eisele, Insurance - Strategic IT-Architecture 9
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

Java EE 7 at a Glance
Markus Eisele, Insurance - Strategic IT-Architecture 16
• 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
