Spring 4 on Java 8 / Spring.IO on Cloudfoundry

SPEAKER: Jürgen Höller   COMPANY: Pivotal Inc.
SPEAKER: Agim Emruli   COMPANY: mimacom

Spring has a track record of providing dedicated support for new Java generations in a timely fashion, and now it's right about time to go Java 8: With Spring Framework 4.0, we're providing in-depth support for all relevant OpenJDK 8 features, including lambda expressions, JSR-310 Date and Time, parameter name discovery, and java.util.concurrent enhancements. This talk will start by illustrating basic Spring Framework 4.0 concepts, and selected Java 8 features within Spring's programming model, exploring the impact on application architectures.

Besides timely Java support Spring has been a long supporter of different runtime environments. This talk will continue with the introduction of Spring Boot, a project to run Spring application without any external container. Built on Spring Boot this talk introduces Spring XD a standalone platform to process high-volume data on different environment. The talk will conclude with the introduction of Pivotal CloudFoundry, a PAAS runtime environment for Spring applications.

A Web Application Framework for Administrative Applications

SPEAKER: Joao Silva   COMPANY: CERN

At CERN, GS-AIS is a group responsible for developing, maintaining and supporting CERN administrative application in many areas such as HR, finance, security, access, purchasing, leave, etc.

The group has developed a custom framework using Grails, GWT and JavaScript to ease development of Administrative application (forms with many business, validation and access rules). In this presentation we will give an overview of the framework, its architecture, the decisions that were made along the way, and what are the future plans of the group for it.

Surveillance of CERN Accelerators Logging Processes

SPEAKER: Lukasz Burdzanowski   COMPANY: CERN

CERN Accelerators Logging Service (CALS) is a service which persists data of close to 1 million pre-defined signals coming from heterogeneous sources. These signals range from data related to core infrastructure such as electricity, to industrial data such as cryogenics and vacuum, to beam related data such as beam positions, currents, losses, etc.

Considerable part of the data are coming from multiple instances of Java Logging Processes, running in background continuously 24/7. Diagnostics of the processes is an essential requirement to provide a reliable service as CALS.

This presentation briefly discusses CEP and Esper - an open-source implementation of CEP engine, as well as a prototype of runtime diagnostics tool implemented with Esper. This diagnostics enables us with insight into event-driven environment of Logging processes, looking for possibly suspicious patterns and erratic behaviour within the whole system.
