Definition

The configuration files are the files to add to your container's configuration. It is internally used by some containers and is accessible for you can to add extra files.

This feature is only available for local containers (i.e., not for remote containers nor any kind of deployers).

Explanation

In some cases, it is necessary to enrich your container configuration with extra files. This can be done using Cargo's configFiles option, accessible via the Cargo APIs.

The advantage of using this option is that it can replace configuration properties in your files: simply use, for example, @cargo.servlet.port@ to have it replaced with the port on which the Servlet/JSP container is listening to.

Careful with binary files!

If you want to inject binary configuration files (JAR files, for example), you should use setFileProperty (instead of setConfigFileProperty) with the Java API and <files> and <file> (instead of <configfiles> and <configfile>) with the Maven 3 plugin.

You might for example want to add the advanced login configuration to your JBoss instance.

Example using the Java API

The method's name is setConfigFileProperty rather than addConfigFileProperty; but it actually adds files to the configFiles list.

LocalContainer container = ...;
StandaloneLocalConfiguration configuration = (StandaloneLocalConfiguration) getLocalContainer().getConfiguration();

FileConfig loginConfigXml = new FileConfig();
loginConfigXml.setConfigfile("src/main/jboss5/login-config.xml");
loginConfigXml.setToDir("conf");
configuration.setConfigFileProperty(loginConfigXml);

FileConfig sampleRolesProperties = new FileConfig();
sampleRolesProperties.setConfigfile("src/main/jboss5/sample-roles.properties");
sampleRolesProperties.setToDir("conf");
configuration.setConfigFileProperty(sampleRolesProperties);

FileConfig sampleUsersProperties = new FileConfig();
sampleUsersProperties.setConfigfile("src/main/jboss5/sample-users.properties");
sampleUsersProperties.setToDir("conf");
configuration.setConfigFileProperty(sampleUsersProperties);

Example using the ANT tasks

<cargo containerId="@{containerId}" action="@{action}">
  <configuration home="${configuration.home}">
    <configfile file="${basedir}/src/main/jboss5/login-config.xml" todir="conf"/>
    <configfile file="${basedir}/src/main/jboss5/sample-roles.properties" todir="conf/props"/>
    <configfile file="${basedir}/src/main/jboss5/sample-users.properties" todir="conf/props"/>
  </configuration>
</cargo>

Example using the Maven 3 plugin

<plugin>
  <groupId>org.codehaus.cargo</groupId>
  <artifactId>cargo-maven3-plugin</artifactId>
  <configuration>
    <container>
      [...]
    </container>
    <configuration>
      <type>standalone</type>
      [...]
      <configfiles>
        <configfile>
          <file>${project.basedir}/src/main/jboss5/login-config.xml</file>
          <todir>conf</todir>
        </configfile>
        <configfile>
          <file>${project.basedir}/src/main/jboss5/sample-roles.properties</file>
          <todir>conf/props</todir>
        </configfile>
        <configfile>
          <file>${project.basedir}/src/main/jboss5/sample-users.properties</file>
          <todir>conf/props</todir>
        </configfile>
      </configfiles>
    </configuration>
  </configuration>
</plugin>

More advanced example: adding the jetty-env.xml file

To define a central jetty-env.xml file and reuse it later from your WARs, you can proceed as follows:

  1. As explained on the top of this page, use a standalone local container (i.e., not an embedded configuration)

  2. Make sure the property JettyPropertySet.CREATE_CONTEXT_XML (i.e. cargo.jetty.createContextXml) is set to false; so that CARGO doesn't create a context.xml file for your WAR's deployable but rather copies it from the source to the configuration home folder.

  3. For each deployable, make sure the deployable is defined as an expanded WAR; as explained on the Static deployment of expanded WAR page.

  4. Finally, for each deployable, add the following to your local container's configuration:

    <configfiles>
  <configfile> 
    <file>${basedir}/src/main/config/jetty-env.xml</file>
    <todir>webapps/webapp-context/WEB-INF</todir>
  </configfile>
</configfiles>

    ... where webapp-context is the Web application's context

This way:

  • To deploy your WAR, CARGO will copy your WAR's expanded version (i.e., the WAR directory) into the webapps subdirectory of the Jetty configuration
  • Once the WAR is copied, CARGO will also copy the jetty-env.xml file into that WAR's WEB-INF directory

As a reference, please find below the full configuration for Jetty 7.x:

<configuration>
  <container>
    <containerId>jetty7x</containerId>
    <zipUrlInstaller>
      <url>
        http://download.eclipse.org/jetty/7.6.3.v20120416/dist/jetty-distribution-7.6.3.v20120416.zip
      </url>
    </zipUrlInstaller>
  </container>
  <configuration>
    <home>${project.build.directory}/jetty-home</home>
    <properties>
      <cargo.jetty.createContextXml>false</cargo.jetty.createContextXml>
    </properties>
    <configfiles>
      <configfile>
        <file>${project.basedir}/src/main/config/jetty-env.xml</file>
        <todir>webapps/datasource-war/WEB-INF</todir>
      </configfile>
    </configfiles>
  </configuration>
