Why and how to engage a Complex Event Processor from a Java Web ApplicationLucas Jellema
Complex Event Processors are capable of handling large volumes of events - by filtering, aggregating or detecting patterns. Java Applications use a CEP to pre-process incoming signals. These applications can also generate the events - for example the user click and navigation behavior in the web application - and report them to the CEP. The web application can subsequently utilize the outcomes from the CEP to for example intelligently guide the user or present relevant details. This session will show various ways in which a CQL based CEP can be integrated into a Java application to enhance the web application's behavior.
The intended audience for this presentation consists of experience Web Java and Enterprise Java developers.
- introduction to Complex Event Processing
- demonstration of CQL event processing on events arriving on JMS
- discussion of how the web application can absorb the CEP results
- demonstration of a simple Web Shop application that published events to the CEP and utilizes the CEP results
- discussion on when and how CEP can add value to Java applications
La máquina virtual y la plataforma Java se está convirtiendo en el pilar de multiples lenguajes: Java, Scala, Groovy, Clojure, Ceylon, JRuby... pero muchos desarrolladores no conocen como funciona por dentro tanto el sistema de memoria como el recolector de basura. Este conocimiento es fundamental y puede marcar la diferencia entre dos programadores.
Esta charla consisitirá en una introducción a la gestión de memoria de la JVM (Hotspot), cómo trabaja el recolector de basura o algunas opciones para poder configurar las opciones por defecto.
Si alguna vez te has cruzado con un OutOfMemoryError y no entendistes la línea que copiastes de StackOverflow: esta es tu charla.
Enterprise Java Web Application Frameworks Sample Stack ImplementationMert Çalışkan
This document provides an overview of enterprise Java web application frameworks and sample stack implementations. It discusses choosing between various UI, controller, model, and integration frameworks like JSF, Spring, Hibernate, and Apache CXF. It then demonstrates a sample stack using these technologies along with Maven, Eclipse, and other tools. The aim is to provide a scalable and high-performance MVC architecture using proven open source solutions.
Modern web application development with java ee 7Shekhar Gulati
This document discusses building a modern Java web application called Miles2Run using Java EE 7. It describes the initial requirements of allowing users to store running activities and authenticate using Twitter. The technology stack used includes Java EE 7, AngularJS, MySQL, and deployment on WildFly running on OpenShift. Challenges in meeting all requirements and technologies used to overcome them like Redis, MongoDB and C3.js for graphs are also summarized.
The document discusses several key technologies for developing Java web applications, including Java Servlet technology, WebWork framework, Spring framework, and Apache Maven build tool. It provides an overview of how each technology addresses common problems like stateless communication, business logic implementation, view generation, and data access overhead. Examples are given showing how WebWork and Spring can be used together with Maven to build a simple "Hello World" application that follows the MVC pattern and leverages dependency injection.
The document discusses REST (REpresentational State Transfer), an architectural style for building distributed systems. It covers REST concepts like resources, representations, URIs, HTTP methods, caching, and versioning. It provides guidance on designing RESTful APIs, including determining resources, supported methods, and return codes. Content negotiation and tools for testing REST APIs are also mentioned.
