- <h3><font face="Myriad
Web,Arial"><a name="FAQ-GENERAL-EJB"></a>What is Enterprise JavaBeans (EJB)
?</font></h3>
- <p><font face="Myriad
Web,Arial">Enterprise JavaBeans (EJB) is a <a
href="http://java.sun.com/products/ejb/docs.html">specification and architecture</a>
for the development and deployment of component-based, distributed business
applications on the Java platform. 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>

- <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>

- <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>

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"> </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>

- <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>

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

- <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. There can be no hard time limits in Open
Source but pGO hope to have a production quality beta of JBoss 2 by Q4
2000. </font></p>
- <p><font face="Myriad
Web,Arial">pGO is a goal-oriented programme that has successfully galvanised even the
most hardcore and eternally galvanised members of the JBoss community. The goal?. A
finished, production version of JBoss 2 that covers EJB1.1, basic integration
with other J2EE components. We will essentially provide the "essentials of
J2EE" in open source.</font></p>

different name) will move JBoss on towards EJB2.0 compliance and some advanced
features (some have started) but it will take longer, probably around Q1
2001.</font></p>

you must adhere to the license of that third party plug-in <i>in addition</i> to the

directly must be GPL.</font></p>
- <p><font face="Myriad

- <p><font face="Myriad
Web,Arial">This is a very common question and there are a couple options. The key is
to provide the correct server into the environment so that InitialContext performs its
lookup on the correct machine. One option is to set a couple system properties with
the correct information, another is to hard-code the properties, and a third option is
to use a standard jndi.properties file. Forget the hard-code option, here are the
others:</font></p>
- <ul>
- <li><font
face="Myriad Web,Arial">System Properties Specify java.naming.factory.initial and
java.naming.provider.url when you start your client. </font>
-<pre><font face="Myriad Web,Arial"><code> java -cp $CLASSPATH <br>
--Djava.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
</code></font></br>
-<code> -Djava.naming.provider.url=remote.host.name <br>
org.opengroupware.logic.test.AuthenticateTest</code></font>
-</font></pre>
- <li><font
face="Myriad Web,Arial">jndi.properties Create a file called jndi.properties with the
following two lines (and put the jndi.properties file into the classpath of the
client): </font>
- <pre><font
face="Myriad Web,Arial"><code>
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory</code></font></br>
-<font face="Myriad Web,Arial"><code>

-<font face="Myriad Web,Arial"><code> </code></font></ul>

-
-</pre>
- <p><font face="Myriad
Web,Arial">For both of the options above, the instantiation of the InitialContext with
use the default constructor: </font></p>
- <pre><font
face="Myriad Web,Arial"><code> Object reference = new InitialContext().lookup(
"encryption.NoCrypt" );</code></font></pre>
- <p><font face="Myriad

same as if the beans were in the same jar. Configure EJB references as described in

resource.</font></p>

+ <h3><font face="Myriad
Web,Arial"><a name="FAQ-GENERAL-EJB"></a>What is Enterprise JavaBeans (EJB)
?</font></h3>
+ <p><font face="Myriad
Web,Arial">Enterprise JavaBeans (EJB) is a <a
href="http://java.sun.com/products/ejb/docs.html">specification and architecture</a>
for the development and deployment of component-based, distributed business
applications on the Java platform. 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>

+ <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>

+ <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>

+ <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>

+ <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>

+ <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>

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

+ <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 efforts underway 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>

directly must be GPL.</font></p>

+ <p><font face="Myriad
Web,Arial">This is a very common question and there are a couple options. The key is
to provide the correct server into the environment so that InitialContext performs its
lookup on the correct machine. One option is to set a couple system properties with
the correct information, another is to hard-code the properties, and a third option is
to use a standard jndi.properties file. Forget the hard-code option, here are the
others:</font></p>
+
+ <ul>
+ <li><font face="Myriad Web,Arial">System Properties
+ Specify java.naming.factory.initial and
java.naming.provider.url
+ when you start your client. </font>
+ <pre><font face="Myriad Web,Arial"><code> java
-cp $CLASSPATH
+ -Djava.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
</code></font>
+<code> -Djava.naming.provider.url=remote.host.name <br>
org.opengroupware.logic.test.AuthenticateTest</code>
+</pre>
+ <li><font face="Myriad Web,Arial">jndi.properties
+ Create a file called jndi.properties with the
+ following two lines (and put the jndi.properties
+ file into the classpath of the client):</font>
+ <pre><font face="Myriad Web,Arial"><code>
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory</code></font>
+ <font face="Myriad Web,Arial"><code>
java.naming.provider.url=remote.host.name</code></font>
+ <font face="Myriad Web,Arial"><code>
</code></font></pre>
+ </ul>
+
+
+<p><font face="Myriad Web,Arial">For both of the options above, the instantiation
of the InitialContext with use the default constructor: </font></p>
+ <pre><font
face="Myriad Web,Arial"><code> Object reference = new InitialContext().lookup(
"encryption.NoCrypt" );</code></font></pre>
+ <p><font face="Myriad
Web,Arial">Obviously, you need to narrow that object reference - this is just an
example of getting a reference from JNDI.</font></p>

is a great place to start. Don't overlook the mailing list archives for the various
components. As you get into the code, the jboss-dev mailing list is the best place to
direct your questions. The javadocs come with the binary distribution (in the docs
directory), or you can create the javadocs from the source with 'build
javadocs'.</font></p>
