Spring Web Flow The sweet spot for Spring Web Flow are stateful web applications with controlled navigation such as checking in for a flight, applying for a loan, shopping cart checkout, or even adding a confirmation step to a form. What these scenarios have in common is one or more of the following traits: There is a clear start and an end point.The user must go through a set of screens in a specific order.The changes are not finalized until the last step.Once complete it shouldn't be possible to repeat a transaction accidentally Spring Web Flow provides a declarative flow definition language for authoring flows on a higher level of abstraction. It allows it to be integrated into a wide range of applications without any changes (to the flow programming model) including Spring MVC, JSF, and even Portlet web applications.
Aspect-oriented programming AOP includes programming methods and tools that support the modularization of concerns at the level of the source code, while "aspect-oriented software development" refers to a whole engineering discipline. Logging exemplifies a crosscutting concern because a logging strategy necessarily affects every logged part of the system. Logging thereby crosscuts all logged classes and methods. History[edit] Gregor Kiczales and colleagues at Xerox PARC developed the explicit concept of AOP, and followed this with the AspectJ AOP extension to Java.
Development Tool Suite for Enterprise Java The Spring Tool Suite is an Eclipse-based development environment that is customized for developing Spring applications. It provides a ready-to-use environment to implement, debug, run, and deploy your Spring applications, including integrations for Pivotal tc Server, Pivotal Cloud Foundry, Git, Maven, AspectJ, and comes on top of the latest Eclipse releases. Included with the Spring Tool Suite is the developer edition of Pivotal tc Server, the drop-in replacement for Apache Tomcat that's optimized for Spring.
Using Spring to Send JMS Messages Recently I stumbled upon a number of places in the some docs and mailing lists where claims are made that the Spring JmsTemplate is full of anti-patterns, is horribly inefficient and shouldn't be used. Well I'm here to debunk these erroneous claims by pointing out a class in the Spring Framework that was overlooked entirely. The Spring JmsTemplate is a convenience class for sending and receiving JMS messages in a synchronous manner. The JmsTemplate was originally designed to be used with a J2EE container where the container provides the necessary pooling of the JMS resources (i.e., connections, consumers and producers).
www.tuaw.com/about Established December 5, 2004, The Unofficial Apple Weblog (TUAW) is a resource for all things Apple and beyond. TUAW publishes news stories, credible rumors and how-to's covering a variety of topics daily. As a trusted tech blog, TUAW provides opinion and analysis on the news in addition to the facts. Team Blog A bit over a year ago we released Vaadin 7 renewing the framework inside out. Then came push support with 7.1. Now what? Let’s take a look into the future. Open SOA Collaboration Last month an alliance of leading vendors announced progress on specifications to define a language-neutral programming model for application development in SOA environments. They call this specification Open SOA Collaboration. In essence, they are proposing a new standard to create and manage IT, making the process of integrating different third-party SOA technologies "less onerous," they say.
Spring Framework The Spring Framework is an open source application framework and inversion of control container for the Java platform. The framework's core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE platform. Although the framework does not impose any specific programming model, it has become popular in the Java community as an alternative to, replacement for, or even addition to the Enterprise JavaBean (EJB) model.
February 2010 Have you ever had a need to create your own JMS consumer? Or will you have this need in the future? If you answered yes to either one of these questions, this post will simplify your life. war plugin The WAR Plugin is responsible for collecting all artifact dependencies, classes and resources of the web application and packaging them into a web application archive. Usage General instructions on how to use the WAR Plugin can be found on the usage page. Some more specific use cases are described in the examples given below. To share common resources across multiple web applications, see the documentation about using overlays. Last but not least, users occasionally contribute additional examples, tips or errata to the plugin's wiki page.
Service-oriented architecture See also the client-server model, a progenitor concept A Service-Oriented Architecture (SOA) is a design pattern in which software/application components provide services to other software/application components via a protocol, typically over a network and in a loosely-coupled way. The principles of service-orientation are independent of any vendor, product or technology.[1] A service is a self-contained unit of functionality, such as retrieving an online bank statement.[2] By that definition, a service is a discretely invokable operation.
Hibernate (Java) Hibernate is a free software that is distributed under the GNU Lesser General Public License. Mapping Java classes to database tables is accomplished through the configuration of an XML file or by using Java Annotations. When using an XML file, Hibernate can generate skeleton source code for the persistence classes. This is unnecessary when annotations are used. Hibernate can use the XML file or the annotations to maintain the database schema. Hibernate supports the mapping of custom value types.
Tuning JMS Message Consumption In Spring In a previous blog post titled Using Spring to Receive JMS Messages, I introduced the use of the Spring default message listener container for asynchronous consumption of JMS messages. One very common discovery that folks make when first using JMS is that producers can send messages much faster than consumers can receive and process them. When using JMS queues, I always recommend the use of more consumers than you have producers. (When using JMS topics, you should only use a single consumer to guard against receiving the same message multiple times.)
