Returns:

the ServletContext object that corresponds to the named URL

getResource

public java.net.URL getResource(java.lang.String pPath)
                         throws java.net.MalformedURLException

Returns the resource that is mapped to a specified path. The path must be in the form /dir/dir/file.ext.

This method allows the Web server to make a resource available to a servlet from any source. Resources can be located on a local or remote file system, in a database, or on a remote network site.

This method can return null if no resource is mapped to the pathname.

The servlet engine must implement the URL handlers and URLConnection objects that are necessary to access the resource.

This method has a different purpose than java.lang.Class.getResource, which looks up resources based on a class loader. This method does not use class loaders.

Specified by:

getResource in interface javax.servlet.ServletContext

Parameters:

pPath - a String specifying the path to the resource, in the form /dir/dir/file.ext

Returns:

the resource located at the named path, or null if there is no resource at that path

Throws:

java.net.MalformedURLException - if the pathname is not given in the correct form

getResourceAsStream

public java.io.InputStream getResourceAsStream(java.lang.String pPath)

Returns the resource located at the named path as an InputStream object.

The data in the InputStream can be of any type or length. The path must be of the form /dir/dir/file.ext. This method returns null if no resource exists at the specified path.

Metainformation such as content length and content type that is available when you use the getResource method is lost when you use this method.

The servlet engine must implement the URL handlers and URLConnection objects necessary to access the resource.

This method is different from java.lang.Class.getResourceAsStream, which uses a class loader. This method allows servlet engines to make a resource available to a servlet from any location, without using a class loader.

Specified by:

getResourceAsStream in interface javax.servlet.ServletContext

Parameters:

pPath - a String specifying the path to the resource, in the form /dir/dir/file.ext

Returns:

the InputStream returned to the servlet, or null if no resource exists at the specified path

getResourcePaths

public java.util.Set getResourcePaths(java.lang.String pPath)

Specified by:

getResourcePaths in interface javax.servlet.ServletContext

getRequestDispatcher

public javax.servlet.RequestDispatcher getRequestDispatcher(java.lang.String pUrlPath)

Returns a RequestDispatcher object that acts as a wrapper for the resource located at the named path. You can use a RequestDispatcher object to forward a request to the resource or include a resource in a response.

The pathname must be in the form /dir/dir/file.ext. This method returns null if the ServletContext cannot return a RequestDispatcher.

The servlet engine is responsible for wrapping the resource with a RequestDispatcher object.

Specified by:

getRequestDispatcher in interface javax.servlet.ServletContext

Parameters:

pUrlPath - a String specifying the pathname to the resource

Returns:

a RequestDispatcher object that acts as a wrapper for the resource at the path you specify

See Also:

RequestDispatcher

getNamedDispatcher

Specified by:

getAttributeNames in interface javax.servlet.ServletContext

Returns:

an Enumeration of attribute names

See Also:

getAttribute(java.lang.String)

setAttribute

public void setAttribute(java.lang.String pName,
                java.lang.Object pObject)

Gives an attribute a name in this servlet context. If the name specified is already used for an attribute, this method will overwrite the old attribute and bind the name to the new attribute.

Attribute names should follow the same convention as package names. The Java Servlet API specification reserves names matching java.*, javax.*, and sun.*.

Specified by:

setAttribute in interface javax.servlet.ServletContext

Parameters:

pName - a String specifying the name of the attribute

pObject - an Object representing the attribute to be given the name

removeAttribute

public void removeAttribute(java.lang.String pName)

Removes the attribute with the given name from the servlet context. If you remove an attribute, and then use getAttribute(java.lang.String) to retrieve the attribute's value, getAttribute returns null.

Specified by:

removeAttribute in interface javax.servlet.ServletContext

Parameters:

pName - a String specifying the name of the attribute to be removed

getInitParameter

public java.lang.String getInitParameter(java.lang.String pName)

Specified by:

getInitParameter in interface javax.servlet.ServletContext

getInitParameterNames

public java.util.Enumeration<java.lang.String> getInitParameterNames()

GenericContext does not have any mechanism for specifying init params. To use this feature you must place your servlet in a Web Application.
