Constructor Detail

ServletContextImpl

public ServletContextImpl()

Method Detail

initListeners

protected void initListeners(ArrayList<String> listeners)

Notify the ServletContextListener that we are starting.

destroyListeners

protected void destroyListeners()

Stop ServletContextListener

getContextPath

public String getContextPath()

Specified by:

getContextPath in interface ServletContext

setContextPath

protected void setContextPath(String contextPath)

Programmatically set the context path of the Servlet.

Parameters:

contextPath -

getContext

public ServletContext getContext(String uri)

Return a ServletContext object that corresponds to a specified URI on the server. This method allows servlets to gain access to the context for various parts of the server, and as needed obtain RequestDispatcher objects or resources from the context. The given path must be absolute (beginning with a "/"), and is interpreted based on our virtual host's document root.

Specified by:

getContext in interface ServletContext

Parameters:

uri - Absolute URI of a resource on the server

getMajorVersion

public int getMajorVersion()

Return the major version of the Java Servlet API that we implement.

Specified by:

getMajorVersion in interface ServletContext

getMinorVersion

public int getMinorVersion()

Return the minor version of the Java Servlet API that we implement.

Specified by:

getMinorVersion in interface ServletContext

getMimeType

public String getMimeType(String file)

Return the MIME type of the specified file, or null if the MIME type cannot be determined.

Specified by:

getMimeType in interface ServletContext

Parameters:

file - Filename for which to identify a MIME type

getResourcePaths

public Set getResourcePaths(String path)

Return a Set containing the resource paths of resources member of the specified collection. Each path will be a String starting with a "/" character. The returned set is immutable.

Specified by:

getResourcePaths in interface ServletContext

Parameters:

path - Collection path

getResource

public URL getResource(String path)
                throws MalformedURLException

Return the URL to the resource that is mapped to a specified path. The path must begin with a "/" and is interpreted as relative to the current context root.

Specified by:

getResource in interface ServletContext

Parameters:

path - The path to the desired resource

Throws:

MalformedURLException - if the path is not given in the correct form

getResourceAsStream

public InputStream getResourceAsStream(String path)

Return the requested resource as an InputStream. The path must be specified according to the rules described under getResource. If no such resource can be identified, return null.

Specified by:

getResourceAsStream in interface ServletContext

Parameters:

path - The path to the desired resource.

getRequestDispatcher

public RequestDispatcher getRequestDispatcher(String arg0)

Specified by:

getRequestDispatcher in interface ServletContext

getNamedDispatcher

public RequestDispatcher getNamedDispatcher(String arg0)

Specified by:

getNamedDispatcher in interface ServletContext

normalize

protected String normalize(String path)

Return a context-relative path, beginning with a "/", that represents the canonical version of the specified path after ".." and "." elements are resolved out.
