 org.directwebremoting.impl.ContainerUtil
| ContainerUtil | | public class ContainerUtil (Code) | | An abstraction of all the common servlet operations that are required to host
a DWR service that depends on the servlet spec.
It would be good to have a base class for all servlet operations, however
lack of MI prevents us from doing this.

| Method Summary | |
| public static void | configure(Container container, List<Configurator> configurators)
| | public static void | configureContainerFully(Container container, ServletConfig servletConfig)
| | public static boolean | configureFromAnnotations(Container container)
Annotations must not break 1.3, so we use reflection to create an
org.directwebremoting.annotations.AnnotationsConfigurator
and the catch all sorts of random exceptions for the benefit of
Websphere. | | public static void | configureFromDefaultDwrXml(Container container)
| | public static boolean | configureFromInitParams(Container container, ServletConfig servletConfig)
Add configurators from init params to the end of the list of
configurators. | | public static void | configureFromSystemDwrXml(Container container)
Configure using the system dwr.xml from within the JAR file. | | public static Container | createAndSetupDefaultContainer(ServletConfig servletConfig)
A combination of
ContainerUtil.createDefaultContainer(ServletConfig) and
ContainerUtil.setupDefaultContainer(DefaultContainer,ServletConfig) . | | public static DefaultContainer | createDefaultContainer(ServletConfig servletConfig)
Create a
DefaultContainer , allowing users to upgrade to a child
of DefaultContainer using an
ServletConfig init parameter of
org.directwebremoting.Container. | | public static void | createUrlMapping(DefaultContainer container, String url, String propertyName, Class<? extends Handler> handler)
Creates entries in the
Container so 2 lookups are possible.
| | public static void | debugConfig(Container container)
| | public static List<Container> | getAllPublishedContainers(ServletContext servletContext)
Get a list of all known Containers for the given
ServletContext
Parameters:
servletContext - The context in which Containers are stored. | | public static ServerContext | getSingletonServerContext()
If there is only once instance of DWR defined in a ServletContext then
we can get at it using this method. | | public static void | prepareForWebContextFilter(ServletContext context, ServletConfig config, Container container, WebContextBuilder webContextBuilder, HttpServlet servlet)
Make some changes to the ServletContext so
DwrWebContextFilter can find the Container etc. | | public static void | publishContainer(Container container, ServletConfig servletConfig)
If helps some situations if people can get at the container by looking
in the servlet context, under some name. | | public static void | resolveContainerAbstraction(DefaultContainer container, ServletConfig servletConfig)
We need to decide which
ContainerAbstraction should be the
default for this
Container , also we should prepare the default
ServerLoadMonitor . | | public static void | setupDefaultContainer(DefaultContainer container, ServletConfig servletConfig)
Setup a
DefaultContainer . | | public static void | setupDefaults(DefaultContainer container)
| | public static void | setupFromServletConfig(DefaultContainer container, ServletConfig servletConfig)
| | public static void | shutdownServerLoadMonitorsInContainerList(List<Container> containers, String title)
Internal use only. |
| ATTRIBUTE_CONTAINER_LIST | | final public static String ATTRIBUTE_CONTAINER_LIST(Code) | | The name under which we publish all
Container s.
|
| DEFAULT_SERVERCONTEXT_NAME | | final public static String DEFAULT_SERVERCONTEXT_NAME(Code) | | We store a single ServerContext in the contextMap under this name.
|
| INIT_CONFIG | | final public static String INIT_CONFIG(Code) | | Init parameter: Set a dwr.xml config file.
This is only a prefix since we might have more than 1 config file.
|
| INIT_CUSTOM_CONFIGURATOR | | final public static String INIT_CUSTOM_CONFIGURATOR(Code) | | Init parameter: If you wish to use a custom configurator, place its
class name here
|
| INIT_LOGLEVEL | | final public static String INIT_LOGLEVEL(Code) | | Init parameter: If we are doing Servlet.log logging, to what level?
|
| INIT_SKIP_DEFAULT | | final public static String INIT_SKIP_DEFAULT(Code) | | Init parameter: Skip reading the default config file if none are specified.
|
| configure | | public static void configure(Container container, List<Configurator> configurators)(Code) | | Allow all the configurators to have a go at the container in turn
Parameters:
container - The container to configure
Parameters:
configurators - A list of configurators to run against the container |
| configureFromAnnotations | | public static boolean configureFromAnnotations(Container container)(Code) | | Annotations must not break 1.3, so we use reflection to create an
org.directwebremoting.annotations.AnnotationsConfigurator
and the catch all sorts of random exceptions for the benefit of
Websphere.
Parameters:
container - The container to configure true if the configuration worked. |
| debugConfig | | public static void debugConfig(Container container)(Code) | | Create a bunch of debug information about a container
Parameters:
container - The container to print debug information about |
| getSingletonServerContext | | public static ServerContext getSingletonServerContext()(Code) | | If there is only once instance of DWR defined in a ServletContext then
we can get at it using this method.
The one-and-only ServerContext or null if there are more than 1. |
| prepareForWebContextFilter | | public static void prepareForWebContextFilter(ServletContext context, ServletConfig config, Container container, WebContextBuilder webContextBuilder, HttpServlet servlet)(Code) | | Make some changes to the ServletContext so
DwrWebContextFilter can find the Container etc.
Parameters:
context - The servlet context
Parameters:
config - The servlet configuration
Parameters:
container - The container to save in the ServletContext
Parameters:
webContextBuilder - The WebContextBuilder to save
Parameters:
servlet - The Servlet to save |
| publishContainer | | public static void publishContainer(Container container, ServletConfig servletConfig)(Code) | | If helps some situations if people can get at the container by looking
in the servlet context, under some name.
The name is specified in an initParameter.
Parameters:
container - The container to publish
Parameters:
servletConfig - Source of initParams to dictate publishing and contexts to publish to |
| shutdownServerLoadMonitorsInContainerList | | public static void shutdownServerLoadMonitorsInContainerList(List<Container> containers, String title)(Code) | | Internal use only.
If we detect that the server is being shutdown then we want to kill
any reverse ajax threads.
Parameters:
containers - The list of containers to look for ServerLoadMonitors in
Parameters:
title - What causes this (for debug purposes) |
