| javax.servlet |
|
The javax.servlet package contains a number of classes and interfaces that
describe and define the contracts between a servlet class and the
runtime environment provided for an instance of such a class by a
conforming servlet container.
|
| Java Source File Name | Type | Comment |
| Filter.java | Interface | A filter is an object that performs filtering tasks on either the request to a resource (a servlet or static content), or on the response from a resource, or both.
Filters perform filtering in the doFilter method. |
| FilterChain.java | Interface | A FilterChain is an object provided by the servlet container to the developer
giving a view into the invocation chain of a filtered request for a resource. |
| FilterConfig.java | Interface | A filter configuration object used by a servlet container
to pass information to a filter during initialization. |
| GenericServlet.java | Class | Defines a generic, protocol-independent
servlet. |
| RequestDispatcher.java | Interface | Defines an object that receives requests from the client
and sends them to any resource (such as a servlet,
HTML file, or JSP file) on the server. |
| Servlet.java | Interface | Defines methods that all servlets must implement.
A servlet is a small Java program that runs within a Web server.
Servlets receive and respond to requests from Web clients,
usually across HTTP, the HyperText Transfer Protocol. |
| ServletConfig.java | Interface | A servlet configuration object used by a servlet container
to pass information to a servlet during initialization. |
| ServletContext.java | Interface | Defines a set of methods that a servlet uses to communicate with its
servlet container, for example, to get the MIME type of a file, dispatch
requests, or write to a log file.
There is one context per "web application" per Java Virtual Machine. |
| ServletContextAttributeEvent.java | Class | This is the event class for notifications about changes to the attributes of the
servlet context of a web application. |
| ServletContextAttributeListener.java | Interface | Implementations of this interface receive notifications of
changes to the attribute list on the servlet context of a web application. |
| ServletContextEvent.java | Class | This is the event class for notifications about changes to
the servlet context of a web application. |
| ServletContextListener.java | Interface | Implementations of this interface receive notifications about
changes to the servlet context of the web application they are
part of. |
| ServletException.java | Class | Defines a general exception a servlet can throw when it
encounters difficulty. |
| ServletInputStream.java | Class | Provides an input stream for reading binary data from a client
request, including an efficient readLine method
for reading data one line at a time. |
| ServletOutputStream.java | Class | Provides an output stream for sending binary data to the
client. |
| ServletRequest.java | Interface | Defines an object to provide client request information to a servlet. |
| ServletRequestAttributeEvent.java | Class | This is the event class for notifications of changes to the
attributes of the servlet request in an application. |
| ServletRequestAttributeListener.java | Interface | A ServletRequestAttributeListener can be implemented by the
developer interested in being notified of request attribute
changes. |
| ServletRequestEvent.java | Class | Events of this kind indicate lifecycle
events for a ServletRequest. |
| ServletRequestListener.java | Interface | A ServletRequestListener can be implemented by the developer
interested in being notified of requests coming in and out of
scope in a web component. |
| ServletRequestWrapper.java | Class | Provides a convenient implementation of the ServletRequest interface that
can be subclassed by developers wishing to adapt the request to a Servlet.
This class implements the Wrapper or Decorator pattern. |
| ServletResponse.java | Interface | Defines an object to assist a servlet in sending a response to the client.
The servlet container creates a ServletResponse object and
passes it as an argument to the servlet's service method.
To send binary data in a MIME body response, use
the
ServletOutputStream returned by
ServletResponse.getOutputStream .
To send character data, use the PrintWriter object
returned by
ServletResponse.getWriter . |
| ServletResponseWrapper.java | Class | Provides a convenient implementation of the ServletResponse interface that
can be subclassed by developers wishing to adapt the response from a Servlet.
This class implements the Wrapper or Decorator pattern. |
| SingleThreadModel.java | Interface | Ensures that servlets handle
only one request at a time. |
| UnavailableException.java | Class | Defines an exception that a servlet or filter throws to indicate
that it is permanently or temporarily unavailable. |
