Jt 2.7 has been released – 14 Aug 2008

The latest version Jt 2.7 of Java Pattern Oriented Framework has been released on 14 Aug 2008. It facilitates rapid implementation of java applications for large critical systems. Jt implements some popular java patterns like Data Access Objects (DAO), J2EE and GoF patterns.

Jt 2.7 is about to bring enhancements to the Jt components and Jt Automated Wizard (Jt Wizard). Jt wizard is capable of generating framework applications automatically which are based on java design patterns like DAO, Jt messaging, MVC, GoF etc. The Jt wizard available currenty is integrated with the concepts of Hibernate (DAO) and Struts (MVC). Jt wizard can automatically create the DAO mapping files, MVC configuration files, JSP and other Java Classes. It is a nice example of a reference web application built on top of the Jt framework. 

The newest features that are included in this release can be summerized as below-

·  It implements the J2EE design patterns J2EE business delegate, J2EE Session Facade, J2EE Service Locator and J2EE Value Object.

·   It implemets Web Services adapters and proxies for web services integrations and simplifies web services development and deployment  using Jt messaging API.

·       It provides a jBPM Adaptor for Business Process Modelling (BPM) integration. jBPM is an open source technology which helps users to build powerful business process models with the implenetation of Jt application using a Process Graph.

·   Jt also integrates with MVC and AJAX design patterns. A transparent interface between these technologies and Jt framework API is provided by the Universal Jt components and and Adapters.

·    It integrates with Hibernate Data Access Objects through a transparent interface provided by a Jt Adapter.

·          A JDBC Adapter provides integration with JDBC.

·     Request log, Undoable operations and Querying mechanisms are supported by the Command Pattern (JtCommand) implementation.

·          A JavaMail Adapter is provided for JavaMail API integration.

·      Jt Adapters and proxies are implemented to integrate with J2EE EJBs providing  the clients transparent and easy access to the framework objects.

·    Customization of the framework applications can be done easily by using Resource files that provide the facility of automatic loading of object attributes.

·         Jt framework can be integrated with JSP (Java Server Pages) also.

·     It provides XML API integration powered by built-in XML/Bean mapping facilities and XML Adapters.

This open source java technology is based on a simple messaging architecture that enables encapsulation and loose coupling of framework objects. The Jt components can be plugged into complex framework applications by transposing with each other using a “lego” approach.

Java pattern oriented framework defines the following goals and requirements-

Java Parallel Processing Framework (JPPF) version 1.4 is now available – Wednesday, 20 Aug 2008

JPPF has recently announced the availability of the Version 1.4 in the market.

The very best new features included in JPPF version 1.4 are-

·          The new JPPF library has the build and version information.

·        It provides the facility of restart or shutdown of nodes from a distant Administration console or by using the API.

·    Features in automatic load-balancing between local and remote executions which facilitates the clients to process their tasks locally.

·          Implementation of multi-core multi-CPU hardware.

·          Same codes can be processed purely in both local and distributed way or also in an integrated manner.

·          In the distributed execution of small computing tasks, the overhead is minimized or disappeared.

·    To carry out a much easier implementation of the technology, the nodes security policy can be downloaded form the server.

·          Collection of the CPU time used by the tasks is done by the nodes.

The open source JPPF (Java Parallel Processing Framaework) Community is based on java technology dealing in Grid Computing. It enables the applications to run in parallel and also accelerates their execution. It applies the popular java idiom “write once, deploy once, run everywhere”.

The JPPF has a three-tiered architecture comprising of the following three layers-

· Client Layer: This layer includes an API and communication tools which enable the submission and execution of the tasks by the framework in parallel.

· Service Layer: This layer provides interface for the between the clients and the nodes. It also manages the execution queue, the load-balancing and recovery features. It is responsible for the dynamic loading of both framework and application classes onto the appropriate nodes.

·  Execution Layer: This layer consists of the nodes which execute individual tasks and  return the execution results. The nodes dynamically request the JPPF driver for the code needed to execute the client tasks.

The basic features of a JPPF framework are-

·         A JPPF Grid can be uploaded and run easily and quickly, only in a few minutes.

·      It is a simple programming model which deals with the complexity of distributed and parallel processing.

·  It features as a highly scalable java framework for distributed execution of CPU-related tasks.

·          It seamlessly integrates with the J2EE application servers.

·          It provides graphical tools that monitors and administers the executions.

·       It provides highly reliable services featuring self-repair and fault-tolerence abililities.

·          It includes a completely documented sample JPPF applications providing solution to real-life problems.

·          It can be run on any platform that is based on the java technology.

·          It is an source project featuring a flexible, business-friendly licensing policy.

Release or Stripes 1.5 (18 Aug 2008)

Stripes is an open source and action-based Java framework of presentation layer developed to create web applications using the   latest Java based technologies. Stripes is developed to minimise XML configuration to make web development easier and productive. It integrates with Spring and Hibernate framework. The very recent release of this product is the Stripes version 1.5. Some of the improvement features and bug fixes of this release includes-

·   Lesser Configuration: Stripes has the ability to automatically locate and use the extensions of the application involved. Examples of such extensions are TypeConverter, Formatter, ExceptionHandler, ActionBeanContext, etc. Most applications now can be configured with only two parameters, viz., Extension.Packages and ActionResolver.Packages.

·    Clean URLs: The request parameters can be used and validated as normal parameters and by embedding them into the request URL. Clean URL is supported by s:link, s:url and s:form. For having greater flexibility, the new DynamicMappingFilter can be used.

·          Binding Access Control: To restrict the binding only to the desired properties can be done by using @StrictBinding Annotation. However, in special situations the “policy”, “allow” and “deny” elements are also used by annotation.

·          Easier Formatters and TypeConverters: The implementation of the Formatters and the TypeConverters can be done now by the use of autodiscovery. There is no need to extend the DefaultFormatterFactory and the DefaultTypeConverterfactory. Improvement of the DefaultFormatterFactory supports inheritance and interfaces. 

·          Partial Forms: Parrtial forms can be nested in other form tagsby using a new attribute partial=”true|false” in the s:form tag. This makes possible for AJAX code that returns HTML snippets to the client to contain form inputs.

·          Client Cache Control: Caching of a response by a client can be controlled by the implementation of the new @HttpCache annotation to an ActionBean class and/or event handler method.

Goals of Stripes:

(i) The basic aim of Stripes is to make web development in Java easier.
(ii) Though Stripes is simple in its deployment it gives us powerful solutions regarding common prpoblems.
(iii) Stripes enables developers to build their applications at a faster rate.
(iv) Stripes provides great extensibility of its use without the need of much configuration.

The normal flow of the events and the componets of an application developed using Stripes can be shown as below

Figure. Typical Stripes flow

The prime difference between Stripes and other action-based frameworks is that in Stripes the external configuration files are absent. Uses of annotations and the convention over configuration allow Srtipes to bring more development denying clutters.

Comparision of Stripes with the similar technology Apache Wicket:

(i)      Stripes is an action-based model whether Wicket is component-based.

(ii)    Stripes concentrates on the request-response nature of HTTP whether Wicket tries to make web development more likely the desktop applications.

(iii)    Stripes applies basically the concepts of Struts technology whether Wicket is easier to learn with the concepts of Swing.

(iv)   Stripes enables us to use AJAX framework whether Wicket has built-in AJAX suppport. 

Release of Simple 4.0 – the Java HTTP Engine  (18 Aug 2008)

The new Version 4.0 of  the Simple HTTP framework of Java has been released recently. It is intended to provide faster XML configuration and serialization. The Simple Version 4.0 is asynchronous and has the ability to take large amount of loads comprising of only a limited servicing threads. The NIO (New Input Output) framework of Java is implemented at the transport layer thus by ensuring itself to be responsive and resource efficient. Simple 4.0 also provides an API more suitable to the needs of the deveopers as compared to a Java Servlet API.

The basic salient features of this release includes-

·          High Performance HTTP Kernel: Simple has already outshadowed theperformances of other HTTP servers. As compared to the latest versions of AsyncWeb and Jetty, it has higher throughput and performs much better in attaining the desired goals.

·          Asynchronous Processing Throughput: Simple is well developed asynchronous HTTP engine.  Its service model implements a transparent internal monitoring system which drives the request completion process. This implementation has triggered the performance of Simple to be better than other servlet engines which are basically rely on servicing threads to monitor the request completion. Simple is especially better in regard of response time featuring transactions based on distributed services.

·          Embeddable Framework:  Simple can be embedded into any already existed application comprising several lines of code. It incorporates with any form of environments which supports Spring framework.

·          Small Footprint: Though Simple has highly proficient in attaining its objectives under increasing load, it deals with only a small amount of memory. A latest study has showed that its memory footprint is half the size of other NIO based technologies like AsyncWeb and Jetty.

·          Self Contained: It is not dependent on other technology specifications except the Java 5 SDK . This feature of Simple has retains the memory size to be small and so there no compatitibility problem arises regarding its integration with other existing application.

·          Open Source Development: Simple has been released under LGPL (Lesser General Public License) which makes it adaptable for  the commercial and open source projects development.
