Method Detail
addLifecycleListener
- void addLifecycleListener(java.util.EventListener eventListener)
Adds a lifecycle event listener to this context. The listner can be any
of the standard listeners mandated by the Servlet 2.4 specification.
Parameters:
eventListener
- removeLifeCycleListener
- void removeLifeCycleListener(java.util.EventListener eventListener)
Removes an existing listener from this context's list of listeners.
NOTE: Listeners of the type HttpSessionListener currently have no way of
being removed.
Parameters:
eventListener
- getWebAppConfig
- WebAppConfig getWebAppConfig()
Returns the configuration object associated with this context
Returns:
getFilterManager
- WebAppFilterManager getFilterManager( )
Returns the web app filter manager associated with this context.
Returns:
isFiltersDefined
- boolean isFiltersDefined()
Returns whether or not filters are defined with this context.
Returns:
createServletWrapper
- IServletWrapper createServletWrapper( IServletConfig sconfig)
- throws java.lang.Exception
Convenience method that creates an IServletWrapper given the servlet config.
Parameters:
sconfig
- Returns:
Throws:
java.lang.Exception
targets
- java.util.Iterator targets()
Returns an iterator of all the targets currently loaded (not necessarily
initialized) by this context. The target objects are all RequestProcessors,
and may be either IServletWrappers or ExtensionProcessors
Returns:
getMappingTarget
- RequestProcessor getMappingTarget( java.lang.String mapping)
Returns the target that matches (according to the rules under servlet
mappings in the servlet spec.) the given mapping.
Parameters:
mapping
- Returns:
addMappingTarget
- void addMappingTarget(java.lang.String mapping,
- RequestProcessor target)
- throws java.lang.Exception
Adds a target against a specified mapping into this context
Parameters:
mapping
- target
- Throws:
java.lang.Exception
containsTargetMapping
- boolean containsTargetMapping(java.lang.String mapping)
replaceMappingTarget
- void replaceMappingTarget(java.lang.String mapping,
- RequestProcessor target)
- throws java.lang.Exception
Replaces the target for the specified mapping in this context
Parameters:
mapping
- target
- Throws:
java.lang.Exception
createFilterConfig
- IFilterConfig createFilterConfig( java.lang.String id)
Creates a IFilterConfig object for this context
Parameters:
id
- Returns:
addMappingFilter
- void addMappingFilter(java.lang.String mapping,
- IFilterConfig config)
Adds a filter against a specified mapping into this context
Parameters:
mapping

- java.lang.ClassLoader getClassLoader( )
Returns the classLoader that this context used to load its resources
Returns:
startEnvSetup
- void startEnvSetup(boolean transactional)
- throws java.lang.Exception
Called by components leveraging the webcontainer to set up the environments necessary
(1) Namespace - to enable namespace lookups
(2) Setup the classloader on the thread to be that of the WebApp.
(3) Depending on the transactional parameter passed, setup transaction related environment
Parameters:
transactional
- Throws:
java.lang.Exception
finishEnvSetup
- void finishEnvSetup(boolean transactional)
- throws java.lang.Exception
Called by components leveraging the webcontainer to tear down the environment that was setup
