JBoss is an open source project, sponsored by Red Hat, aimed at building a Java-based middleware application server.
An application server is a software engine that delivers applications to client computers or devices. The main benefit of an application server is the ease of application development, since applications need not be built from scratch, but are assembled from building blocks provided by the application server.
Middleware is a piece of software that connects two or more software applications so that they can exchange data.
The functions of the Jboss Application Server is to act as an open source code tool to allow individuals or businesses to create applications. It can be used for debugging and as a learning tool. It is based on Java.
An XA transaction, in the most general terms, is a "global transaction" that may span multiple resources. A non-XA transaction always involves just one resource. An XA transaction involves a coordinating transaction manager, with one or more databases (or other resources, like JMS) all involved in a single global transaction. Non-XA transactions have no transaction coordinator, and a single resource is doing all its transaction work itself (this is sometimes called local transactions). XA transactions come from the X/Open group specification on distributed, global transactions. JTA includes the X/Open XA spec, in modified form. Most stuff in the world is non-XA - a Servlet or EJB or plain old JDBC in a Java application talking to a single database. XA gets involved when you want to work with multiple resources - 2 or more databases, a database and a JMS connection, all of those plus maybe a JCA resource - all in a single transaction. In this scenario, you'll have an app server like Websphere or Weblogic or JBoss acting as the Transaction Manager, and your various resources (Oracle, Sybase, IBM MQ JMS, SAP, whatever) acting as transaction resources. Your code can then update/delete/publish/whatever across the many resources. When you say "commit", the results are commited across all of the resources. When you say "rollback", _everything_ is rolled back across all resources. The Transaction Manager coordinates all of this through a protocol called Two Phase Commit (2PC). This protocol also has to be supported by the individual resources. In terms of datasources, an XA datasource is a data source that can participate in an XA global transaction. A non-XA datasource generally can't participate in a global transaction (sort of - some people implement what's called a "last participant" optimization that can let you do this for exactly one non-XA item).
Developing software using an open-source model is becoming increasingly popular. The main advantages that open-source software has over proprietary (closed-source) software are: * Lower development cost. Individuals and smaller companies may aid in developing the software, reducing the number of programmers you have to pay yourself. * Bug detection and correction. With more people viewing your code from more diverse backgrounds, bugs will be found and fixed faster. This is often referred to as "Linus' Law": 'Given enough eyeballs, all bugs are shallow." * Reuse of code and shorter development time. Code from an older or different project can be incorporated into your new project, reducing the time it takes to create and develop it. * More independence. With a closed source project, you will have great problems if the developer goes out of business and you need your software updated or fixed. With the code open, any company can step in to fill the void. There may be some disadvantages to open-source software from a development perspective, though rarely any from the end-user perspective. The main problems are: * Disclosure of trade secrets. Having the code for a program available implies revealing how it works. This includes disclosure of algorithms and how a device with a unique design might function. Revealing this information to others may cause duplication and loss of financial advantage. * Loss of revenue through traditional sales. If the source is available, then it is unlikely that consumers will pay a large amount for a CD or license. Revenue must instead be garnered through support agreements and OEM customization.
The JBoss ESB system was created to replace the older EAI systems. The Jboss ESB systems were considered a more secure and faster way to store archives than the EAI system.

Number 1 in terms of revenue is IBM with its Websphere and MQSeries brands Number 2 is Oracle (BEA) Other players on the market are: SUN (JBoss, probably part of Oracle soon), Tibco (used in finance industry mostly), and Progress. This list is not complete, however IBM and Oracle are definitely the main players with together more than half of the total market.
