Distinguish Enterprise JavaBean JavaBeans are Code reuse reusable Component based software engineering software components for Java programming language Java that can be manipulated visually in a builder tool. Practically, they are classes written in the Java programming language Java programming language conforming to a particular convention. They are used to encapsulate many objects into a single object the bean , so that they can be passed around as a single bean object instead of as multiple individual objects. A JavaBean is a Java Object that is Serialization serializable , has a nullary constructor , and allows access to properties using Mutator method getter and setter methods . JavaBean conventions In order to function as a JavaBean Class computer science class , an object class must obey certain conventions about method naming, construction, and behavior. These conventions make it possible to have tools that can use, reuse, replace, and connect JavaBeans. The required conventions are as follows The class must have a public default constructor no argument . This allows easy instantiation within editing and activation frameworks. The class property programming properties must be accessible using get , set , is used for boolean properties instead of get and other methods so called Accessor accessor methods and mutator method s , following a standard naming conventions programming naming convention . This allows easy automated inspection and updating of bean state within frameworks, many of which include custom editors for various types of properties. The class should be Serialization Java serializable . It allows applications and frameworks to reliably save, store, and restore the bean s state in a fashion independent of the Virtual machine VM and of the platform. JavaBean ...

It is a component interface that declares the abstract methods to be exposed to the clients. The web service endpoint interface extends the java.rmi.Remote interface, and all the methods of the interface must throw the RemoteException. The methods of a web service endpoint interface are implemented in a stateless session bean class. However, the methods of the class are not required to throw any RemoteException. ref A Web service client accesses a stateless session bean through the bean s Web service endpoint interface. Like a Enterprise JavaBean Remote and local interfaces remote interface , a Web service endpoint interface defines the business methods of the bean. In contrast to a remote interface, a Web service endpoint interface is not accompanied by a Enterprise JavaBean Home interfaces home interface , which defines the bean s life cycle methods.

Unreferenced date November 2007 In computing software , POJO is an acronym for Plain Old Java Object . The name is used to emphasize that a given Object computer science object is an ordinary Java Object, not a special object, and in particular not an Enterprise JavaBean . The term was coined by Martin Fowler , Rebecca Parsons and Josh MacKenzie in September 2000 blockquote We wondered why people were so against using regular objects in their systems and concluded that it was because simple objects lacked a fancy name. So we gave them one, and it s caught on very nicely. ref http www.martinfowler.com bliki POJO.html MF Bliki POJO from MartinFowler.com ref blockquote The term POJO is mainly used to denote a Java object which does not follow any of the major Java object models, conventions, or frameworks such as EJB. The term continues the pattern of older terms for technologies that do not use fancy new features, such as POTS Plain Old Telephone Service in telephony , and PODS Plain Old Data Structures that are defined in C but use only C programming language C language features, and POD Plain Old Documentation in Perl . The equivalent to POJO on the .NET framework is Plain Old CLR Object . Contextual variations The POJO phenomenon has most likely gained widespread acceptance because of the need for a common and easily understood term that contrasts with complicated object frameworks. A JavaBean is a POJO that is Serialization Java serializable , has a no argument Constructor computer science constructor , and allows access to properties using Mutator method getter and setter methods . An Enterprise JavaBean is not a single class but an entire component model though Enterprise JavaBean EJB 3 reduces the complexity of Enterprise JavaBeans . As designs using POJOs have become more commonly used, systems have arisen that give POJOs some of the functionality used in frameworks and more choice about which areas of functionality are actually needed.

Unreferenced date December 2009 POV date December 2008 Notability Other Computer science date January 2009 In object oriented programming , a BaseBean is a utility object from which concrete entities are derived via subclassing . design pattern computer science Proper design suggests that the inherited functionality should be provided via Delegation computer science delegation instead. The BaseBean is an example of an anti pattern where the Bean part of the name comes from the standard Java programming language Java naming convention for a generic entity object, or JavaBean . Using inheritance causes the derived class to rely on the internals of a base class which may be out of the control of the developer. While the utility classes are typically stable and fairly similar across implementations, some innocuous change in the future fragile base class could break the derived class since the relationship is not well defined . In addition, it muddies the business meaning of the derived class. For example, an order is not a vector, although an order may contain a vector of line items. A class should not inherit from another class simply because the parent class contains functionality needed in the subclass. Instead, delegation has a relationship should be used to obtain the business logic or data structure that is required. In technical terms, this case warrants composition over inheritance . In some cases a static utility class can be created to contain necessary functionality. Object oriented programming emphasizes that objects should be meaningful and should communicate with each other in the way that resembles the real world entities they are emulating. A BaseBean is not a real world object, nor is it descriptive. Likely, it needs to be refactored as a more meaningful class and referenced rather than extended. This pattern is somewhat related to the CallSuper anti pattern, in which a derived class has the requirement to call into the parent class to complete its work ... more details
Plain Old Common Language Runtime CLR Object or POCO is a play on the term Plain Old Java Object POJO , from the Java Platform, Enterprise Edition Java EE programming world, and is used by developers targeting the Common Language Runtime of the .NET Framework . Similar to the Java context, the term is used to contrast a simple object with one that is designed to be used with a complicated, special object frameworks such as an object relational mapping ORM component. Another way to put it is that POCOs are objects unencumbered with inheritance or attributes needed for specific frameworks ref See, for example, this MSDN article http msdn.microsoft.com en us library cc681329.aspx Data Contracts POCO Support ref . In .NET terms, the word is most often used in the programmatic sense, to differentiate a non Serviced Component see Microsoft Transaction Server MTS from a standard object . It can also be used in a tongue in cheek manner, referencing the perceived complexity of Java based programming frameworks such as Enterprise JavaBean EJB . POCO is often incorrectly expanded to Plain Old C Sharp programming language C Object , but POCOs can be created with any language targeting the CLR.

Merge Unified Expression Language date October 2009 Expression Language EL is a scripting language which allows access to Java Sun Java components JavaBean s through JavaServer Pages JSP . Since JavaServer Pages JSP 2.0 JSP 2.0 , it has been used inside JavaServer Pages JSP tags to separate Java code from JSP, and to allow easier access to Java components than in Java code . Evolution of EL occurred to make scripting easier for web content designers who have little or practically no knowledge of the core Java Language. This scripting language makes JSP a scripting language in the true sense. Before EL, JSP consisted of some special tags like scriptlet s, expressions etc within which Java code was written explicitly. With EL the web content designer needs only to know how to make proper calls to core Java methods and can enjoy the true scripting flavour of a scripting language. EL is, both syntactically and semantically, similar to JavaScript expressions there is no typecasting type conversions are usually done implicitly double and single quotes are equivalent code object.property code has the same meaning as code object property code EL also liberates the programmer from having to know the particularities of how the values are actually accessed code object.property code can mean depending on what the code object code is either code object.get property code or code object.getProperty property code or code object.getProperty code etc. See also OGNL An open source expression language used by WebWork and Struts 2 .

mergeto Enterprise JavaBean discuss Talk Session Beans Merger proposal date February 2011 In the Java Platform, Enterprise Edition specifications, a Session Bean is a type of Enterprise JavaBean Enterprise Bean . The only other type is the Message driven bean . Legacy EJB versions from before 2006 EJB3 had a third type of bean, the Entity Bean . In EJB 3.0 Java EE 5 those Entity Beans have been replaced by Java Persistence API entities. Contrary to JPA Entities, which represent persistent data maintained in a database, a Session Bean implements a business task and is hosted by an EJB container . A session bean performs operations, such as calculations or database access, for the client. Although a session bean can be transactional, it is not recoverable should a system crash occur. Session bean objects either can be stateless or can maintain conversational state Java EE conversational state across methods and transactions. If a session bean maintains state, then the EJB container manages this state if the object must be removed from memory. However, the session bean object itself must manage its own persistent data. Stateless Session Beans A stateless session bean is an object that does not have an associated conversational state, but may have instance state. It does not allow concurrent access to the bean. The contents of instance variables are not guaranteed to be preserved across method calls. All instances of a stateless session bean should be considered identical by the client.

Java Authentication and Authorization Service , or JAAS , pronounced Jazz , is a Java programming language Java security framework for user centric security to augment the Java code based security. Since Java Virtual Machine Java Runtime Environment 1.4 JAAS has been integrated with the JRE previously JAAS was supplied as an extension library by Sun. JAAS s main goal is to separate the concerns of user authentication so that they may be managed independently. Administration For the system administrator, JAAS consists of two kinds of configuration file .login.conf specifies how to plug vendor supplied login modules into particular applications .policy specifies which identities users or programs are granted which permissions For example, an application may have this login.conf file indicating how different authentication mechanisms are to be run to authenticate the user PetShopApplication com.sun.security.auth.module.LdapLoginModule sufficient com.foo.SmartcardLoginModule requisite com.sun.security.auth.module.UnixLoginModule required debug true Application interface For the application developer, JAAS is a standard library that provides a representation of identity Principal and a set of credentials Subject a login service that will invoke your application callbacks to ask the user things like username and password. It returns a new Subject a service that tests if a Subject was granted a permission by an administrator. Security system integration For the security system integrator, JAAS provides interfaces to provide your identity namespace to applications to attach credentials to threads Subject for developing login modules. Your module invokes callbacks to query the user, checks their response and generates a Subject .

Advert date December 2007 Cleanup laundry date January 2008 Winstone is a GNU General Public License LGPL licensed servlet container that was written out of a desire to provide Java Servlet functionality with a minimum of unnecessary features. It is not intended to be a completely fully functional Java Platform, Enterprise Edition Java EE style servlet container implementation. Winstone does not support API s unrelated to Java Servlets, such as JavaMail , Enterprise JavaBean s, etc. Other Servlet container implementations, such as Jakarta Tomcat Tomcat , Jetty web server Jetty , Resin Server Resin , JRun, and Weblogic can provide the missing functionality. The original goals in writing Winstone were Supply fast, reliable servlet container functionality for a single Web application web app per server this restriction is lifted as of v0.7 Keep the size of the core distribution jar as low as possible currently 155KB Keep configuration files to an absolute minimum, using command line options to optionally override sensible compiled in defaults.
