Configuration and Usage

* Introduction

  The EAR plugin allows to generate automatically the descriptor deployment, e.g.
  application.xml. This generation is already customized by the goal's
  parameters, see {{{plugin-info.html}the goals description}}.

* Configuring the EAR Plugin

  The configuration of the EAR Plugin is not any different with the configuration
  of the other plugins. The configuration should be similar to:

+-----
<project>
  [...]
  <build>
    [...]
    <plugins>
      [...]
      <plugin>
        <artifactId>maven-ear-plugin</artifactId>
        <configuration>
          <!-- configuration elements goes here -->
        </configuration>
      </plugin>
   [...]
</project>
+-----

  When configuring the EAR Plugin in your pom.xml, you do not declare any
  \<executions\> elements in it because it is always invoked at least once
  during the package phase of an <<<ear>>> project.

* Executing and Generating your EAR Package

  The EAR Plugin replaces the Jar Plugin when your project \<packaging\> is
  <<<ear>>>. So to generate your EAR package, you need only call the package
  phase like so:

+-----
mvn package
+-----

* Advanced Configuration

  Any EAR module might be further customized as follows:

   * <<bundleDir>>: the directory in the EAR structure where the artifact will be
   stored.

   * <<bundleFileName>>: the name of the artifact in the EAR structure.

   * <<uri>>: the complete path in the EAR structure for the artifact.

   * <<excluded>>: excludes the artifact from the generated ear.

   * <<unpack>>: unpack the artifact in the generated ear.

  The context root of a Web module might be customized using the contextRoot
  parameter.

  Please note that third party libraries (i.e. JarModule) are not included
  in the generated application.xml (only ejb-client should be included in
  a <java> entry). However, a jar dependency could be included in the
  generated application.xml by specifying the <<<includeInApplicationXml>>> flag.

  It is also possible to specify a default bundle directory for all third party
  libraries by specifying the <<<defaultLibBundleDir>>> parameter.

  The security settings might be specified under the security parameter.

  The artifact's types that should be unpacked by default can be specified
  using the unpackTypes parameter

  The file name mapping to use for artifacts stored in the EAR can be specified
  using the <<<fileNameMapping>>> parameter. Valid values for this parameter
  are <<<standard>>> (default) and <<<full>>>. By specifying <<<full>>> as file
  name mapping, artifacts are prefixed by the <<<groupId>>> where dots have been
  replaced by dashes.

  For more information on EAR modules, please see the
  {{{modules.html}modules configuration}} page.

  You can take a look at the examples for more information on these advanced
  configurations.

* JBoss support

  The EAR plugin can generate the jboss-app.xml automatically. To do so, the 'jboss'
  element must be configured and takes the following child elements:

   * <<version>>: the targeted JBoss version to use (3.2 or 4 which is the default).

   * <<security-domain>>: the JNDI name of the security manager (JBoss 4 only)

   * <<unauthenticated-principal>>: the unauthenticated principal (JBoss 4 only)

   * <<jmx-name>>: the object name of the ear mbean.

  Hibernate archives (HAR) and Service archives (SAR) will be recognized automatically
  and added the the jboss-app.xml file.

  You can take a look at the examples for more information on the JBoss support.
