The platform encourages the development of enterprise systems with the ability to run <i>anywhere</i> across a wide range of operating systems.

It is a significant part of Java 2 Enterprise Edition (J2EE) - a unified architecture and platform for delivering the benefits of the Java platform to the server-based computing environment.</font></p> - <p><font face="Myriad Web,Arial">A business component that is developed for the Enterprise JavaBean architecture is also confusingly called an Enterprise JavaBean. These components may be written once, and then deployed on any server platform that supports the Enterprise JavaBeans specification. A key goal of the EJB architecture is to make the job of developing EJB components and the client applications that access them very simple indeed. Much of this is achieved by defining an architectural entity called a <i>container</i> - an EJB container - that acts as a buffer between EJB components and their client as well as between EJB components and the very complex reality of developing scalable, distributed systems. An EJB container is itself contained within an <i>EJB server</i>.</font></p> - <p><font face="Myriad Web,Arial">Further information about Enterprise JavaBeans is available on the <a href="http://java.sun.com/products/ejb/index.html">Enterprise JavaBeans home page</a>.</font></p> - <p><font face="Myriad Web,Arial">Back to <a href="#top_of_faq">FAQ Contents</a></font></p> - <p> </p> - <h3><font face="Myriad Web,Arial"><a name="FAQ-GENERAL-JAVABEANS"></a>Are JavaBeans different from Enterprise JavaBeans ?</font></h3> - <p><font face="Myriad Web,Arial">Yes, JavaBeans are different from Enterprise JavaBeans (EJBs). Both JavaBeans and EJBs are units of packaged functionality but they are designed to function in very specific and different environments. JavaBeans facilitate black box reuse of visual and non-visual components within JavaBean-aware IDEs. EJBs on the other hand are non-visual components that can only be deployed in an EJB-compliant Java application server. </font></p> - <p><font face="Myriad Web,Arial">JavaBeans are basically just classes executed in the JVM, while EJBs are managed objects that are deployed within an EJB application server. JavaBeans may be driven by events, but EJBs are currently just driven by remote method calls.</font></p> - <p><font face="Myriad Web,Arial">Back to <a href="#FAQ_CONTENTS">FAQ Contents</a></font></p> - <p><font face="Myriad Web,Arial"> </font></p> - <h3><font face="Myriad Web,Arial"><a name="FAQ-GENERAL-JAS"></a>What is a Java Application Server ?</font></h3> - <p><font face="Myriad Web,Arial">In the current context, a Java application server is a sophisticated software system that provide a run-time environment for executing components written in Java. The widespread adoption of the EJB standard from the J2EE specification has ensured that a well written component can be without additional development work deployed in almost all Java application servers.</font></p> - <p><font face="Myriad Web,Arial">Back to <a href="#FAQ_CONTENTS">FAQ Contents</a></font></p> - <p><font face="Myriad Web,Arial"> </font></p> - <h3><font face="Myriad Web,Arial"><a name="FAQ-GENERAL-DEPLOYMENT"></a>What does Deployment mean ?</font></h3> - <p><font face="Myriad Web,Arial">Deployment is the act of preparing and sending the bean(s) to the application server to become available as application components. In preparation for deployment, any resources that the bean provider has used in the code must be associated with real resources, transactional attirbutes may be specified, security attributes may be set, and any other container-specific settings will all be specified in deployment descriptors. The compiled code and the deployment descriptors will all be jarred together into an application jar and then the jar will be placed in the necessary location for the application server to use. The final act of deployment is the application server parsing the deployment descriptors, preparing the container environment, and then binding the bean names to the naming service to make them available for calls.</font></p> - <p><font face="Myriad Web,Arial">Back to <a href="#FAQ_CONTENTS">FAQ Contents</a></font></p> - <p><font face="Myriad Web,Arial"> </font></p> - <h3><font face="Myriad Web,Arial"><a name="FAQ-GENERAL-TRANSMGMT"></a>What is Transaction Management ?</font></h3> - <p><font face="Myriad Web,Arial">A transaction is an atomic and reliable unit of program execution . Transactions systems are invaluable in any system that support concurrent processing. For example, if multiple clients are using the same database table concurrently, it's possible that the database write operations they perform could leave the table in an inconsistent state. With transactional support, each user see a transaction as an operation that either completes successfully or not at all. The possibility of inconsistencies arising as result of their interleaved database operations is removed. </font></p> - <p><font face="Myriad Web,Arial">The Enterprise JavaBeans architecture provides automatic support for distributed transactions in component based applications. Such distributed transactions can atomically update data in multiple databases. The burden of managing transactions is thus shifted from the bean developer to the EJB container and/or server.</font></p> - <p><font face="Myriad Web,Arial">Read chapter 11 of the EJB 1.1 spec if you are interested in knowing more about Transaction Management.</font></p> - <p><font face="Myriad Web,Arial">Back to <a href="#FAQ_CONTENTS">FAQ Contents</a></font></p> - <p><font face="Myriad Web,Arial"> </font></p> - <h3><font face="Myriad Web,Arial"><a name="FAQ-GENERAL-PERSISTENCE"></a>What is Bean / Container Managed Persistence ?</font></h3> - <p><font face="Myriad Web,Arial">With respect to Enterprise JavaBeans (EJBs), persistence is a term that describes the process whereby the the state of an active (stateful?) EJB is stored (usually to a database) in such a way that the EJB can be reactivated later. It is serialization for EJBs if you like.</font></p> - <p><font face="Myriad Web,Arial">There are two flavours of persistence in EJB - Bean-Manage Persistence (BMP) and Container-Managed Persistence (CMP). The main difference between the two flavours is who is responsible for <i>actually</i> persisting the EJB. In BMP the bean developer is responsible for writing the code that persists the beans state (maybe using JDBC?) while in CMP, the container is reponsible. In CMP a bean developer might not even <i>know</i> what object-relational database persistence is let alone how it works?. Pretty neat.</font></p> - <p><font face="Myriad Web,Arial">A relevant excerpt from the <a href="http://java.sun.com/products/ejb/docs.html">EJB 1.1. specification</a> itself, on page 100:</font></p> - <p><font face="Myriad Web,Arial">"The entity bean component protocol allows the entity Bean Provider either to implement the entity bean's persistence directly in the entity bean class or in one or more helper classes provided with the entity bean class (bean-managed persistence), or to delegate the entity bean's persistence to the Container Provider tools used at deployment time (container-managed persistence)."<br> - </font></p> - <p><font face="Myriad Web,Arial">Back to <a href="#FAQ_CONTENTS">FAQ Contents</a></font></td> - </tr> - <tr> - <td class="newsheader"><font color="white" face="Myriad Web,Arial" size="3"><a name="FAQ-JBOSS"></a><b>JBoss Questions</b></font></td> - </tr> - <tr> - <td class="newsbody"> - <h3><font face="Myriad Web,Arial"><a name="FAQ-JBOSS-SUMMARY"></a>What is JBoss ?</font></h3> - <p><font face="Myriad Web,Arial">Basically, JBoss is an application server written in Java that can host business components developed in Java. The interface and architecture of the JBoss application server, the Java business components that can be hosted inside JBoss and various protocols by which a client application (or other business components) can interact with the business components is defined by the <a href="http://java.sun.com/products/ejb/docs.html">Enterprise JavaBeans specification</a>.</font></p> - <p><font face="Myriad Web,Arial">JBoss 2 is designed to be an EJB v1.1 container and server. There are <a href="bugzilla/show_bug.cgi?id=109">efforts underway</a> currently to extend the support to EJB v2.0 but the work isn't expected to begin before Q4 2000. The JBoss server is developed in the Open Source tradition by volunteers and sponsors using 100% Pure Java. </font></p> - <p><font face="Myriad Web,Arial">We are working very hard to ensure that JBoss rightfully becomes <i>the</i> premier EJB server for the Java 2 Enterprise Edition.</font></p> - <p><font face="Myriad Web,Arial">Back to <a href="#top_of_faq">FAQ Contents</a></font></p> - <p> </p> - <h3><font face="Myriad Web,Arial"><a name="FAQ-JBOSS-PGOV"></a>What is Project Game Over or PGOV ?</font></h3> - <p><font face="Myriad Web,Arial">Project Games Over (pGO or PGOV) is a co-ordinated set of activities that are designed to produce a production quality jboss2.0 and move us towards jboss3.0 - <i>the</i> integrated j2EE container.

The goal?. A finished, production version of JBoss 2 that covers EJB1.1, basic integration with other J2EE components.

It is a significant part of Java 2 Enterprise Edition (J2EE) - a unified architecture and platform for delivering the benefits of the Java platform to the server-based computing environment.</font></p> + <p><font face="Myriad Web,Arial">A business component that is developed for the Enterprise JavaBean architecture is also confusingly called an Enterprise JavaBean. These components may be written once, and then deployed on any server platform that supports the Enterprise JavaBeans specification. A key goal of the EJB architecture is to make the job of developing EJB components and the client applications that access them very simple indeed. Much of this is achieved by defining an architectural entity called a <i>container</i> - an EJB container - that acts as a buffer between EJB components and their client as well as between EJB components and the very complex reality of developing scalable, distributed systems. An EJB container is itself contained within an <i>EJB server</i>.</font></p> + <p><font face="Myriad Web,Arial">Further information about Enterprise JavaBeans is available on the <a href="http://java.sun.com/products/ejb/index.html">Enterprise JavaBeans home page</a>.</font></p> + + <p><font face="Myriad Web,Arial">Back to <a href="#top_of_faq">FAQ + Contents</a></font></p> + <h3><font face="Myriad Web,Arial"><a name="FAQ-GENERAL-JAVABEANS"></a>Are JavaBeans different from Enterprise JavaBeans ?</font></h3> + <p><font face="Myriad Web,Arial">Yes, JavaBeans are different from Enterprise JavaBeans (EJBs). Both JavaBeans and EJBs are units of packaged functionality but they are designed to function in very specific and different environments. JavaBeans facilitate black box reuse of visual and non-visual components within JavaBean-aware IDEs. EJBs on the other hand are non-visual components that can only be deployed in an EJB-compliant Java application server. </font></p> + <p><font face="Myriad Web,Arial">JavaBeans are basically just classes executed in the JVM, while EJBs are managed objects that are deployed within an EJB application server. JavaBeans may be driven by events, but EJBs are currently just driven by remote method calls.</font></p> + + <p><font face="Myriad Web,Arial">Back to <a href="#FAQ_CONTENTS">FAQ + Contents</a></font><font face="Myriad Web,Arial"> </font></p> + <h3><font face="Myriad Web,Arial"><a name="FAQ-GENERAL-JAS"></a>What is a Java Application Server ?</font></h3> + <p><font face="Myriad Web,Arial">In the current context, a Java application server is a sophisticated software system that provide a run-time environment for executing components written in Java. The widespread adoption of the EJB standard from the J2EE specification has ensured that a well written component can be without additional development work deployed in almost all Java application servers.</font></p> + + <p><font face="Myriad Web,Arial">Back to <a href="#FAQ_CONTENTS">FAQ + Contents</a></font><font face="Myriad Web,Arial"> </font></p> + <h3><font face="Myriad Web,Arial"><a name="FAQ-GENERAL-DEPLOYMENT"></a>What does Deployment mean ?</font></h3> + <p><font face="Myriad Web,Arial">Deployment is the act of preparing and sending the bean(s) to the application server to become available as application components. In preparation for deployment, any resources that the bean provider has used in the code must be associated with real resources, transactional attirbutes may be specified, security attributes may be set, and any other container-specific settings will all be specified in deployment descriptors. The compiled code and the deployment descriptors will all be jarred together into an application jar and then the jar will be placed in the necessary location for the application server to use. The final act of deployment is the application server parsing the deployment descriptors, preparing the container environment, and then binding the bean names to the naming service to make them available for calls.</font></p> + + <p><font face="Myriad Web,Arial">Back to <a href="#FAQ_CONTENTS">FAQ + Contents</a></font><font face="Myriad Web,Arial"> </font></p> + <h3><font face="Myriad Web,Arial"><a name="FAQ-GENERAL-TRANSMGMT"></a>What is Transaction Management ?</font></h3> + + <p><font face="Myriad Web,Arial">A transaction is an atomic and reliable + unit of program execution. Transactions systems are invaluable in + any system that support concurrent processing. For example, if multiple + clients are using the same database table concurrently, it's possible + that the database write operations they perform could leave the + table in an inconsistent state. With transactional support, each + user see a transaction as an operation that either completes successfully + or not at all. The possibility of inconsistencies arising as result + of their interleaved database operations is removed. </font></p> + <p><font face="Myriad Web,Arial">The Enterprise JavaBeans architecture provides automatic support for distributed transactions in component based applications. Such distributed transactions can atomically update data in multiple databases. The burden of managing transactions is thus shifted from the bean developer to the EJB container and/or server.</font></p> + <p><font face="Myriad Web,Arial">Read chapter 11 of the EJB 1.1 spec if you are interested in knowing more about Transaction Management.</font></p> + + <p><font face="Myriad Web,Arial">Back to <a href="#FAQ_CONTENTS">FAQ + Contents</a></font><font face="Myriad Web,Arial"> </font></p> + <h3><font face="Myriad Web,Arial"><a name="FAQ-GENERAL-PERSISTENCE"></a>What is Bean / Container Managed Persistence ?</font></h3> + <p><font face="Myriad Web,Arial">With respect to Enterprise JavaBeans (EJBs), persistence is a term that describes the process whereby the the state of an active (stateful?) EJB is stored (usually to a database) in such a way that the EJB can be reactivated later. It is serialization for EJBs if you like.</font></p> + <p><font face="Myriad Web,Arial">There are two flavours of persistence in EJB - Bean-Manage Persistence (BMP) and Container-Managed Persistence (CMP). The main difference between the two flavours is who is responsible for <i>actually</i> persisting the EJB. In BMP the bean developer is responsible for writing the code that persists the beans state (maybe using JDBC?) while in CMP, the container is reponsible. In CMP a bean developer might not even <i>know</i> what object-relational database persistence is let alone how it works?. Pretty neat.</font></p> + <p><font face="Myriad Web,Arial">A relevant excerpt from the <a href="http://java.sun.com/products/ejb/docs.html">EJB 1.1. specification</a> itself, on page 100:</font></p> + <p><font face="Myriad Web,Arial">"The entity bean component protocol allows the entity Bean Provider either to implement the entity bean's persistence directly in the entity bean class or in one or more helper classes provided with the entity bean class (bean-managed persistence), or to delegate the entity bean's persistence to the Container Provider tools used at deployment time (container-managed persistence)."<br> + </font></p> + + <p><font face="Myriad Web,Arial">Back to <a href="#FAQ_CONTENTS">FAQ + Contents</a></font></p></td> + </tr> + <tr> + <td class="newsheader"><font color="white" face="Myriad Web,Arial" size="3"><a name="FAQ-JBOSS"></a><b>JBoss Questions</b></font></td> + </tr> + <tr> + <td class="newsbody"> + <h3><font face="Myriad Web,Arial"><a name="FAQ-JBOSS-SUMMARY"></a>What is JBoss ?</font></h3> + <p><font face="Myriad Web,Arial">Basically, JBoss is an application server written in Java that can host business components developed in Java.
