Deployables are archives (WAR, EAR, etc) that can be deployed in the container

Explanation

A Deployable class is a wrapper class around a physical archive. Deployable are constructed by directly instantiating them (e.g. new WAR(...) or new TomcatWAR(...)) or by using a DeployableFactory (e.g. DefaultDeployableFactory). There are 2 generic deployable classes:

  • o.c.c.c.deployable.WAR
  • o.c.c.c.deployable.EAR
    There are also some container-specific deployables such as:
  • o.c.c.c.deployable.tomcat.TomcatWAR
  • o.c.c.c.deployable.jboss.JBossWAR
    They are there to support container extensions to archives (for example, Tomcat supports context.xml files located in your WAR's META-INF directory, JBoss allows for a jboss-web.xml located in your WAR, etc).

The DeployableFactory interface offers a principal method for creating a Deployable: DeployableFactory.createDeployable(String containerId, String deployableLocation, DeployableType type). DeployableType can be DeployableType.WAR or DeployableType.EAR.

Once you have a Deployable instance wrapping your archive, you'll need to deploy it. This can be done either using Static Deployment or using Hot Deployment.

Example using the Java API

Deploying a WAR in Tomcat 5.x:

Container container = new Tomcat5xContainer(
    new CatalinaStandalineConfiguration("target/tomcat5x"));
container.setHome("c:/apps/tomcat-5.0.29");

WAR war = new WAR("path/to/my.war");

[...]

Example using the Generic API

[...]

DeployableFactory factory = new DefaultDeployableFactory();
WAR war = factory.createDeployable("tomcat5x", "path/to/my.war", 
    DeployableType.WAR);

Example using the Ant tasks

Statically deploying a WAR in Tomcat 5.x:

<cargo containerId="tomcat5x" home="c:/apps/tomcat-5.0.29" action="start">
  <configuration>
    <war warfile="path/to/my.war"/>
  </configuration>
</cargo>

Example using the Maven 3 plugin

<dependencies>
  [...]
  <dependency>
    <groupId>my.war.groupId</groupId>
    <artifactId>my-war</artifactId>
    <version>1.0.0</version>
    <packaging>war</packaging>
  </dependency>
  [...]
</dependencies>

          <artifactId>my-war</artifactId>

        </deployable>
      </deployables>
    </configuration>
