Aranea is an Open-Source Java MVC Web Framework that provides a common Object-Oriented approach to building the web applications, reusing GUI logic and extending the framework. It comes with out-of-the-box support for nested flows and database-backed query browsing. Additionally it serves as an integration platform, allowing free intermingling of arbitrary frameworks, components and applications.
Apache Camel is a powerful rule based routing and mediation engine which provides a POJO based implementation of the Enterprise Integration Patterns using an extremely powerful fluent API (or declarative Java Domain Specific Language) to configure routing and mediation rules. The Domain Specific Language means that Apache Camel can support type-safe smart completion of routing rules in your IDE using regular Java code without huge amounts of XML configuration files; though Xml Configuration inside Spring is also supported.
Tagonist is a laughably simple java web application framework.
Overview
Tagonist is an ultra-lightweight MVC webapp framework, similar in principle to Struts, WebWork, or Maverick. Like its cousins, Tagonist offers:
* Clean separation of code and content - no need for scriptlets
* Form processing by conveniently populating beans from the HTTP request attributes
However, unlike its cousins, Tagonist:
* Is trivial to learn and use. One look at the examples and you will understand how to write your webapp immediately. There are just two custom tags.
* Is trivial to configure. There no servlets to configure and no XML to muck with. Just drop the tagonist.jar in your WEB-INF/lib and start using the two tagonist custom tags in your JSPs.
* Integrates seamlessly into any JSP-based portal or even other webapp frameworks. Your JSP includes tagonist actions, not the other way around.
* Encourages development of fine-grained actions which can be composed arbitrarily on a page. You don't need to have one action class per screen.
* Allows many HTML developers to work on a project without fighting over checkouts for some sort of XML sitemap configuration file.
* Is composed of 8 java classes and less than 500 lines of code (including whitespace). Anyone can see how it works.
* An ant task called the "propertizer" that automatically generates getter and setter methods when you annotate fields with @Property
GridGain is a computational grid framework. Its goal is to improve general performance of processing intensive applications by splitting and parallelizing the workload. In many cases GridGain is used to achieve better overall throughput, better scalability or availability of services.
Following picture illustrates the basic idea behind processing grids:
In this article, after a quick introduction to Wicket, you will learn to obtain and set up the requisite software for Wicket-based web development. Then you will learn to develop interactive web pages using Wicket. Along the way, you will be introduced to some key Wicket concepts.
jZeno is an open source java full-stack development environment that offers the ability to develop rich web applications. The main architectural goal of jZeno is to allow people to create web applications using pure java development as much as possible. Largely reducing the need to know technologies like javascript, HTML, CSS, database specific SQL, and tons of different APIs. Limiting the amount of APIs, technologies and programming styles allows developers to learn a smaller set of skills much deeper. We think this set of skills should be : a thorough understanding of java, OO development and design patterns.
Stripes is a presentation framework for building web applications using the latest Java technologies. The main driver behind Stripes is that web application development in Java is just too much work! It seems like every existing framework requires gobs of configuration. Struts is pretty feature-light and has some serious architectural issues (see Stripes vs. Struts for details). Others, like WebWork 2 and Spring-MVC are much better, but still require a lot of configuration, and seem to require you to learn a whole new language just to get started.
