• Support for Servlet 3.1

• HTTP Upgrade

New WebServer - Undertow

• HTTP/2 vs. HTTP/1.x

• Binary, instead of textual

• Fully multiplexed, instead of ordered and blocking

• One connection for parallelism

• Header compression to reduce overhead

• Allows servers to “push” responses proactively into client caches

New WebServer - Undertow

Primary goal of HTTP/2 is to reduce latency and make efficient use of the TCP connection.

Batching with JBeret

• EE7 supporting batching

• EAP7.0 supporting batch processes with JBeret project

http://www.oracle.com/technetwork/articles/java/batch-1965499.html

Batching with JBeret

• The job is described by JSL – “Job Specification Language” which is written in xml file

• A job consist of steps which are divided into items

• The job can be operated by servlet or EJB session bean and finally, committed to the DB

<job id="SimplePayrollJob" xmlns=http://xmlns.jcp.org/xml/ns/javaee version="1.0"> <step id="process"> <chunk item-count="2"> <reader ref="simpleItemReader/> <processor ref="simpleItemProcessor/> <writer ref="simpleItemWriter/> </chunk> </step> </job>

Batching with JBeret

• Actually, every Item is implemented by class

• The results of the processing are stored and can be reviewed

<job id="SimplePayrollJob" xmlns=http://xmlns.jcp.org/xml/ns/javaee version="1.0"> <step id="process"> <chunk item-count="2"> <reader ref="simpleItemReader/> <processor ref="simpleItemProcessor/> <writer ref="simpleItemWriter/> </chunk> </step> </job>

Misc. Features

• – Improved Log Viewer

• – Log files appear as resources and can be downloaded

• – Datasource Templates

• – Flush operation for connection pools

• – Enhanced model browser

Quickstarts

• For better understanding how to use EAP 7 technologies, try to use the quickstarts which are coming with each version:

Quickstarts are based on maven

Maven is a build automation tool used primarily for Java projects. The word maven means "accumulator of knowledge" in Yiddish.[3] Maven addresses two aspects of building software: First, it describes how software is built, and second, it describes its dependencies. Contrary to preceding tools like Apache Ant, it uses conventions for the build procedure, and only exceptions need to be written down
