The configuration of operating environment of EJB3.0 learning

Run Environment configuration

1, tool download and installation
1> Download Installation JDK5.0
2> Download Installation eclipse3.2.x
3> Download and install the JBOSS-4.0.4.GA server
4> Download and install MyEclipse5.0 or other plugins
To install JBoss is to pay attention to several points:
1> do not install in the program Files directory, or some applications will lead to inexplicable mistakes.
2> Select Install option with Cluster feature "Ejb3-clustered"
3> When you enter the configuration name, enter "All"
4> When configuring JMX, check all selection referrals and enter Jmx-console username and password!
5 Run JBoss, the JBoss installation directory, into the bin directory, run Run-c all, if run directly, will be an error!
2, understand the use of JBoss directory

Directory	Describe
Bin	Start and close the JBoss script
Client	Java libraries required for client communication with JBoss (JARs)
Docs	Configured sample files (database configuration, etc.)
Docs/dtd	A DTD for various XML files used in JBoss.
Lib	Some jar,jboss are loaded at boot time and are shared by all jboss configurations. (Don't put your library here)
Server	Various JBoss configurations. Each configuration must be placed in a different subdirectory. The name of the subdirectory indicates the name of the configuration. Jboss Contains 3 default configurations: Minimial,default and all, can be selected when you install
Server/all	JBoss is fully configured to start all services, including clustering and IIOP. (This is the configuration for this tutorial)
Server/default	The default configuration for JBoss. Used when no configuration name is specified in the JBoss command air. (This is not installed in this tutorial Configuration, if you do not specify a configuration name, startup will have an error)
Server/all/conf	JBoss's configuration file.
Server/all/data	JBoss's database file. For example, an embedded database, or JBOSSMQ.
Server/all/deploy	The thermal deployment directory for JBoss. Any files or directories placed here will be automatically deployed by JBoss. EJB, WAR, EAR, and even service.
Server/all/lib	Some jar,jboss load them when a specific configuration is started. (The default and Minimial configurations also contain this and the following two directories.) )
Server/all/log	JBoss's log file
Server/all/tmp	The temp file for JBoss

3. EJB Deployment
The deployment process in JBoss is simple and straightforward. In each configuration, JBoss constantly scans for changes in a particular directory:
[JBoss installation directory]/server/config-name/deploy.
