            This is an XML Schema Definition for Geronimo service deployment
            plan. This deployment plan is used for deploying service modules
            which contains non-application GBeans like thread pool, the
            tomcat/jetty container, security manager, etc. In case the Service
            deployment plan is provided internally in the java archive, it
            should be named META-INF/geronimo-service.xml. In case the Service
            deployment plan is provided externally, the deployment descriptor
            can be named anything and provided to the deploy tool. All the
            Service deployment plan must specify the top level element as module
            with namespace specified as 
            xmlns="http://geronimo.apache.org/xml/ns/deployment-1.2". The default
            location for this document is
            http://geronimo.apache.org/xml/ns/deployment-1.2

            Typical Geronimo Service Deployment plan will look like this:

                        ClassLoaders of this module. For example, if Log4J was
                        listed here, the module would never see Geronimo's copy
                        of Log4J. If the module provided it's own Log4J JAR it
                        would use that, otherwise it would not be able to load

                        will be treated as hidden. For example, if you specify
                        two filter elements containing "java.util" and
                        "java.lang" then you would really screw up your

                        application from redefining "javax.servlet", so those
                        classes will *always* be loaded from the server instead
                        of from the web web application's own ClassPath.

                        This is used to prevent children configurations to see

                        be achieved by using hidden-classes. However,
                        private-classes is the preferred approach to hide

                        An example of where this is useful is when deploying a

                Refers to either another module running in the server, or
                an entry in the server's Repository.  In either case this effectively uses a
                URI.

                When this is pointing to a repository entry, the URI must have a form
                acceptable to the repository, which is currently a URI consisting of
                Maven-style identifiers separated by slashes (groupId/artifactId/version/type,
                for example, the URI "postgresql/postgresql-8.0-jdbc/313/jar" for a file like
                "repository/postgresql/postgresql-8.0-jdbc-313.jar").

                When this is pointing to a module, the URI should match the
                module's moduleId.  This also looks
                like a Maven-style URI discussed above.

                The artifactType element can take either a straight URI (as in the examples
                above), or maven-style identifier fragments (groupId, type, artifactId, and
                version), which it will compose into a URI by adding up the fragments with
                slashes in between.

                There is a correspondence between the xml format and a URI.  For example, the URI

                postgresql/postgresql-8.0-jdbc/313/jar

                corresponds to the xml:

                <groupId>postgresql</groupId>

            The import element is restrictive.  The default (when omitted) is to include the specified dependency in
            the classloader (as a parent or URL) and (if the dependency is a module) make sure it is started
            before starting the current module.  Specifying "classes" means that the classes must be included
            in the current module's classloader but the dependency does not need to be started. (I'm not sure this
            is actually possible, but it is what is meant).  Specifying "services" means that the dependency (a module)
            must be started before the current module, but it is not included as a parent classloader.

            You probably never need to use the import element.
