             Descriptor descriptor)

Specified by:
  `start` in class `IterativeDescriptorProcessor`

           Descriptor descriptor)

Specified by:
  `end` in class `IterativeDescriptorProcessor`

#### visitEnvEntry

    public void visitEnvEntry(WebAppContext context,
                     Descriptor descriptor,
                     XmlParser.Node node)
                       throws Exception

JavaEE 5.4.1.3

Parameters:
  `node` -
Throws:
  `Exception`

#### visitResourceRef

    public void visitResourceRef(WebAppContext context,
                        Descriptor descriptor,
                        XmlParser.Node node)
                          throws Exception

Common Annotations Spec section 2.3: resource-ref is for: - javax.sql.DataSource - javax.jms.ConnectionFactory - javax.jms.QueueConnectionFactory - javax.jms.TopicConnectionFactory - javax.mail.Session - java.net.URL - javax.resource.cci.ConnectionFactory - org.omg.CORBA_2_3.ORB - any other connection factory defined by a resource adapter TODO If web.xml contains a resource-ref with injection targets, all resource-ref entries of the same name are ignored in web fragments. If web.xml does not contain any injection-targets, then they are merged from all the fragments. If web.xml does not contain a resource-ref element of same name, but 2 fragments declare the same name it is an error. resource-ref entries are ONLY for connection factories the resource-ref says how the app will reference the jndi lookup relative to java:comp/env, but it is up to the deployer to map this reference to a real resource in the environment. At the moment, we insist that the jetty.xml file name of the resource has to be exactly the same as the name in web.xml deployment descriptor, but it shouldn't have to be Maintenance update 3.0a to spec: Update Section 8.2.3.h.ii with the following - If a resource reference element is specified in two fragments, while absent from the main web.xml, and all the attributes and child elements of the resource reference element are identical, the resource reference will be merged into the main web.xml. It is considered an error if a resource reference element has the same name specified in two fragments, while absent from the main web.xml and the attributes and child elements are not identical in the two fragments. For example, if two web fragments declare a with the same element but the type in one is specified as javax.sql.DataSource while the type in the other is that of a java mail resource, then an error must be reported and the application MUST fail to deploy.

Parameters:
  `node` -
Throws:
  `Exception`

                      throws Exception

Bind a resource with the given name from web.xml of the given type with a jndi resource from either the server or the webapp's naming environment. As the servlet spec does not cover the mapping of names in web.xml with names from the execution environment, jetty uses the concept of a Link, which is a subclass of the NamingEntry class. A Link defines a mapping of a name from web.xml with a name from the execution environment (ie either the server or the webapp's naming environment).

Parameters:
  `name` - name of the resource from web.xml
  `typeClass` -
Throws:
  `Exception`
