Appendix A. Server Directory Structure

If you used the zip installation method, installing JBoss Enterprise Application Platform creates a top level directory named jboss-eap-<version>.
If you used the GUI installer, you have defined a custom directory named during installation. In this guide we refer to this top-level directory as the <$JBOSS_HOME> directory.

Table A.1. <JBOSS_HOME>/jboss-as directory structure

Directory Description Important Notes
bin Contains start up, shut down and other system-specific scripts. Basically all the entry point JARs and start scripts included with the JBoss distribution are located in the bin directory. It also contains the configuration scripts which can be used to configure the JVM parameters.
client Stores configuration files and JAR files that may be used by a Java client application (running outside JBoss) or an external web container. You can select archives as required or use jbossall-client.jar.
Unlike early versions of the JBoss Enterprise Application Platform, the jbossall-client.jar is now a MANIFEST only JAR file.
So if the client application copies over the jbossall-client.jar to its classpath, then it also has to copy over all the other jar files listed in the META-INF/MANIFEST.MF file of jbossall-client.jar.
Furthermore, all these JARs, including the jbossall-client.jar, must be placed in the same folder in the client classpath.
The lib sub-directory within this common directory, contains all the JAR files which are common to the server configuration sets.
Keeping all common JAR files in one place (rather than in the lib folder of each of the server configuration) reduces the size of the server. It also helps with maintenance as there are fewer files to maintain.
Like some of the other configuration paths, the common and the common/lib directories are available as the system properties jboss.common.base.url (This holds the URL to <JBOSS_HOME>/jboss-as/common directory) and jboss.common.lib.url (This holds the URL to <JBOSS_HOME>/jboss-as/common/lib directory).
Contains the XML DTDs, schemas used in JBoss for reference (these are also a useful source of documentation on JBoss configuration specifics).
This directory also contains example JCA (Java Connector Architecture) configuration files for setting up datasources for different databases (such as MySQL, Oracle, Postgres).
lib Contains start up JARs used by JBoss. This directory contains an endorsed sub-directory which is used as one of the Java Endorsed directories. Refer to the Java Endorsed Standards for more details. Do not place your own JAR files in these directories.
server Contains the server profile sets discussed above. Each of the subdirectories is a different server profile. JBoss ships with minimal, default, production, standard, web and all profile sets. The subdirectories and key configuration files contained in the default profile set are discussed in more detail in subsequent sections.


Do not remove any configuration or JRA files from the common directory location. You may add your own JAR files in the common/lib directory if those JAR files are meant to be used by all the server profile sets.
If you want the JAR files to be available for all the applications deployed in a single server profile (for example, the production profile), then the best location to place these JARs is the <JBOSS_HOME>/server/<PROFILE>/lib directory.

A.1. Server Profile Directory Structure

The directory server profile you are using is effectively the server root while JBoss is running. It contains all the code and configuration information for the services provided by the particular server profile.
It is also where the log output goes and where you deploy applications. The table below shows the directories inside the server profile directory (<JBOSS_HOME>/server/<PROFILE>) and their functions.

Table A.2. Server Profile Directory Structure

Directory Description
The conf directory contains the jboss-service.xml, bootstrap.xml bootstrap descriptor file for a given server profile.
The bootstrap.xml in turn points to various other configuration files which comprise the server bootstrap. This defines the core microcontainer beans that are fixed for the lifetime of the server.
The deploy directory contains the hot-deployable services (those which can be added to or removed from the running server). It also contains applications for the current server profile.
You deploy your application code by placing application packages (JAR, WAR and EAR files) in the deploy directory.
The directory is constantly scanned for updates, and any modified components will be re-deployed automatically.
The directory monitored may be configured with the applicationURIs property of the BootstrapProfileFactory bean configuration in the <JBOSS_HOME>/jboss-as/server/<PROFILE>/conf/bootstrap/profile.xml file.
deployers In Enterprise Application Platform 5, unlike earlier versions, the deployers (which are responsible for parsing and deploying applications) are located separately in the <JBOSS_HOME>/jboss-as/server/<PROFILE>/deployers folder. This folder contains various deployer JAR files and their configurations in *-jboss-beans.xml files.
This directory contains JAR files (Java libraries that should not be hot deployed) needed by this server profile. You can add required library files for JDBC drivers and other requirements to this directory.
All JARs in this directory are loaded into the shared classpath at start up. Note that this directory only contains those jars unique to the server profile. Jars common across the server profiles are now located in <JBOSS_HOME>/common/lib.


The file used for configuring the default set of ports for the server is available in the <PROFILE>/conf/bindingservice.beans/META-INF folder. The name of the file is bindings-jboss-beans.xml. See the port configuration section for more details on how to use this file.

A.1.1. The default Server Profile File Set

The default server profile file set is located in the <JBOSS_HOME>/server/default directory.
Many of the items in the default profile are found in other pre-configured profile. The sections below will discuss some of these files, their location and their use.
