    • visitEnvEntry

      public void visitEnvEntry(WebAppContext context, Descriptor descriptor, XmlParser.Node node) throws Exception
      JavaEE 5.4.1.3
      Parameters:
      context - the context
      descriptor - the descriptor
      node - the xml node
      Throws:
      Exception - if unable to process jndi bindings

    • 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
      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 <resource-ref> with the same <resource-ref-name> 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:
      context - the context
      descriptor - the descriptor
      node - the xml node
      Throws:
      Exception - if unable to bind nodes, or load classes

    • visitResourceEnvRef

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

      Throws:
      Exception - if unable to load classes, or bind jndi entries

    • visitMessageDestinationRef

      public void visitMessageDestinationRef(WebAppContext context, Descriptor descriptor, XmlParser.Node node) throws Exception
      Common Annotations Spec section 2.3:

      message-destination-ref is for:

      • javax.jms.Queue

      Parameters:

      Throws:
      Exception - if unable to load classes or bind jndi entries

    • visitPostConstruct

      public void visitPostConstruct(WebAppContext context, Descriptor descriptor, XmlParser.Node node)
      If web.xml has at least 1 post-construct, then all post-constructs in fragments are ignored. Otherwise, post-constructs from fragments are merged. post-construct is the name of a class and method to call after all resources have been setup but before the class is put into use
      Parameters:
      context - the context
      descriptor - the descriptor
      node - the xml node

    • visitPreDestroy

      public void visitPreDestroy(WebAppContext context, Descriptor descriptor, XmlParser.Node node)
      pre-destroy is the name of a class and method to call just as the instance is being destroyed
      Parameters:
      context - the context
      descriptor - the descriptor
      node - the xml node

    • addInjections

      public void addInjections(WebAppContext context, Descriptor descriptor, XmlParser.Node node, String jndiName, Class<?> valueClass)
      Iterate over the <injection-target> entries for a node
      Parameters:
      context - the context
      descriptor - the descriptor
      node - the xml node
      jndiName - the jndi name
      valueClass - the value class

    • bindEnvEntry

      public void bindEnvEntry(String name, Object value) throws Exception
      Parameters:
      name - the jndi name
      value - the value
      Throws:
      Exception - if unable to bind entry

    • makeEnvEntryInjectionsAndBindings

      public void makeEnvEntryInjectionsAndBindings(WebAppContext context, Descriptor descriptor, XmlParser.Node node, String name, String type, String value) throws Exception
      Make injections and any java:comp/env bindings necessary given an env-entry declaration. The handling of env-entries is different to other resource declarations like resource-ref, resource-env-ref etc because we allow the EnvEntry (@see org.eclipse.jetty.plus.jndi.EnvEntry) class that is configured externally to the webapp to specify a value that can override a value present in a web.xml descriptor.
      Parameters:
      context - the WebAppContext of the env-entry
      descriptor - the web.xml, web-default.xml, web-override.xml or web-fragment.xml
      node - the parsed xml representation of the env-entry declaration
      name - the name field of the env-entry
      type - the type field of the env-entry
      value - the value field of the env-entry
      Throws:
      Exception - if there is an unspecified problem

    • bindResourceRef

      public void bindResourceRef(WebAppContext context, String name, Class<?> typeClass) throws Exception
      Bind a resource reference.

      If a resource reference with the same name is in a jetty-env.xml file, it will already have been bound.

      Parameters:
      context - the context
      name - the jndi name
      typeClass - the type class
      Throws:
      Exception - if unable to bind resource

    • bindResourceEnvRef

      public void bindResourceEnvRef(WebAppContext context, String name, Class<?> typeClass) throws Exception
      Throws:
      Exception

    • bindMessageDestinationRef

      public void bindMessageDestinationRef(WebAppContext context, String name, Class<?> typeClass) throws Exception
      Throws:
      Exception

    • bindEntry

      protected void bindEntry(WebAppContext context, String name, Class<?> typeClass) 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:
      context - the context
      name - name of the resource from web.xml
      typeClass - the type class
      Throws:
      Exception - the exception
