Originally started as a utility language for an application framework, the project is now developed completely independently. MVEL is typically used for exposing basic logic to end users and programmers through configuration such as XML files or Java annotations annotations . It may also be used to parse simple JavaBean expressions. The runtime allows MVEL expressions to be executed either interpretively, or through a pre compilation process with support for runtime bytecode generation to remove overhead. Since MVEL is meant to augment Java based software, it borrows most of its syntax directly from the Java programming language with some minor differences and additional capabilities. For example as a side effect of MVEL s typing model, which treats class and method references as regular variables, it is possible to use both class and function pointers but only for static methods . source lang java millis System.currentTimeMillis get millis time millis source MVEL also allows collections to be represented as folds or projections in a Lisp programming language Lisp like syntax. source lang java namesOfParents parent.name in children in employees source Hello world example source lang java System.out.println Hello, world source MVEL relies on Java namespaces and classes, but does not possess the ability to declare namespaces or classes.

Development Lead by Shane Bryzak of the JBoss Seam Team. Seam 3 Seam 3 is a very active project consisting of over 50 developers and engineers, which provides a modular set of extensions to the Contexts and Dependency Injection CDI programming model. Seam s mission is to provide a fully integrated development platform for building rich, standards based Internet applications tailored for traditional and cloud deployments. Seam 3 is considered by whom date December 2011 to be a more scalable, feature rich set of extensions than Seam 2, which is under maintenance development only. Seam 2 Seam 2 combines the two frameworks Enterprise JavaBean s EJB3 and JavaServer Faces JSF . However, simple Plain Old Java Object POJO s can be used at the back end . One can turn any EJB3 object or any simple POJO object into a Seam component by just using annotations. Once a component becomes a Seam component, it can be accessed through JSF or through other business logic components in a unified manner. Thus, one can access any back end EJB component from the front end by addressing it by its Seam component name. The beauty of this Java web framework is that it incorporates much needed identity management features. Seam 2 introduces the concept of bijection , taken from Spring s dependency injection feature where objects can be in jected or out jected to from assigned va ... more details

Unreferenced date August 2011 EAR Enterprise Archive is a file format used by Java EE for packaging one or more modules into a single archive so that the deployment of the various J2EE application module s onto an application server happens simultaneously and coherently. It also contains XML files called deployment descriptor s which describe how to deploy the modules. Apache Ant Ant or Apache Maven Maven can be used to build EAR files. File structure An EAR file is a standard JAR file format JAR file and therefore a Zip file format Zip file with a .ear extension, with one or more entries representing the modules of the application, and a metadata directory called code META INF code which contains one or more deployment descriptors. Module Developers can embed various artifacts within an EAR file for deployment by application servers A Web module has a Sun WAR file format .war extension. It is a deployable unit that consists of one or more web components, other resources, and a web application deployment descriptor. The web module is contained in a hierarchy of directories and files in a standard web application format. POJO Java classes may be deployed in .jar files. An Enterprise Java Bean module has a .jar extension, and contains in its own code META INF code directory descriptors describing the persistent classes deployed. Deployed entity beans become visible to other components and, if remotely exported, to remote clients. Enterprise JavaBean Message driven beans Message Beans and Session Beans are available for remote access. A Resource Adapter module has a Resource Adapter aRchive .rar extension. Class isolation Most application servers load classes from a deployed EAR file as an isolated tree of Java classloader s, isolating the application from other applications, but sharing classes between deployed modules. For example, a deployed WAR file would be able to create instances of classes defined in a JAR file that was also included in the containing EAR file, ... more details
SAP NetWeaver Application Server is a component of the NetWeaver solution which works as a web application server to SAP AG SAP solutions. From the SAP AG SAP point of view the Web AS is the foundation on which most of their product range runs. All ABAP application servers including the message server represent the application layer of the multi tier architecture of an ABAP based SAP System. These application servers execute ABAP applications and communicate with the presentation components, the database, and also with each other, using the message server. Architecture The architecture of SAP Web Application Server can be separated into 5 areas Presentation layer In the presentation layer, the user interface can be developed with Java Server Pages JSP , Business Server Pages BSP , or with Web Dynpro technology. The underlying business layer provides the business content in Java or ABAP. Business layer The business layer consists of a J2EE certified run time environment that processes the requests passed from the Internet Communication Manager ICM and dynamically generates the responses. The business logic can be written either in ABAP or in Java based on the J2EE standard. Developers can implement business logic and persistence with Enterprise JavaBean s EJB using the J2EE environment. Developers can also access the business objects of applications running in the ABAP environment to benefit from their business logic and persistence. Integration layer The local integration engine is an integral part of SAP Web AS and allows instant connection to SAP XI . The local integration engine provides messaging services that exchange messages between the components that are connected in SAP XI. Connectivity layer The Internet Communication Manager ICM dispatches user interface requests to the presentation layer and provides a single framework for connectivity using various communication protocols. Currently, modules are available for Hypertext Transfer Protocol HTTP , HTTPS ex ... more details
The Internet Foundation Classes IFC were a graphics library for Java originally developed by Netcode Corporation and first released by Netscape Corporation on December 16, 1996. History On April 2, 1997, Sun Microsystems and Netscape Communications Corporation Netscape announced their intention to combine IFC with other technologies to form the Java Foundation Classes ref cite web url http www2.prnewswire.com cgi bin stories.pl?ACCT 104&STORY www story 84048&EDATE title Sun and Netscape to jointly develop Java Foundation Classes publisher Netscape Communications Corporation date 1997 04 02 accessdate 2007 07 14 ref . Ultimately, Sun merged the IFC with other technologies under the name Swing , adding the capability for a pluggable look and feel of the widgets. Because its technology has been merged to constitute Swing Java Swing and Java 2D , IFC is now no longer maintained. Differences with Swing Swing Java Swing draw a lot of features from IFC contrary to Abstract Window Toolkit AWT , IFC were written in pure Java programming language Java , thus being at the time browser independent. IFC already provided two Layout manager s, that would be later included in the standard JDK some IFC components were able to read HTML content from Uniform Resource Locator URL s, but the implementation was still far from reliable. However, Swing also improved IFC in a lot of ways IFC did not have a Model view controller Model View architecture contrary to Swing, the Look and feel of IFC components was written in the components themselves, making it impossible to change it easily.

The Java Transaction API JTA , one of the Java EE Java Enterprise Edition Java EE Application programming interface API s, enables distributed transactions to be done across multiple X Open XA XA resources in a Java programming language Java environment. JTA is a specification developed under the Java Community Process as JSR 907. JTA provides for demarcation of transaction boundaries X Open XA API allowing resources to participate in transactions. X Open XA architecture Unsourced image removed image jtaxadiagram.gif center frame speedy image c 2007 06 24 In the X Open XA architecture, a transaction manager or transaction processing monitor TP monitor , coordinates the transactions across multiple resources such as databases and message queues. Each resource has its own manager. The resource manager typically has its own API for manipulating the resource, for example the Java Database Connectivity JDBC API used by relational databases. In addition, the resource manager allows a TP monitor to coordinate a distributed transaction between its own and other resource managers. Finally, there is the application which communicates with the TP monitor to begin, commit or rollback the transactions. The application also communicates with the individual resources using their own API to modify the resource. JTA implementation of the X Open XA architecture The JTA API consists of classes in two Java package s Javadoc EE package javax.transaction javax transaction Javadoc EE package javax.transaction.xa javax transaction xa The JTA is modelled on the X Open XA architecture, but it defines two different APIs for demarcating transaction boundaries. It distinguishes between an application server such as an Enterprise JavaBean EJB server and an application component. It provides an interface, Javadoc EE package javax.transaction javax transaction TransactionManager , that is used by the application server itself to begin, commit and rollback the transactions. It provides a different ... more details
