conforming servlet container.
|
javax.servlet.http |
The javax.servlet.http package contains a number of classes and interfaces
that describe and define the contracts between a servlet class
running under the HTTP protocol and the runtime environment provided
for an instance of such a class by a conforming servlet container.
|
Modifier and Type | Class and Description |
---|---|
class |
ServletRequestWrapper
Provides a convenient implementation of the ServletRequest interface that
can be subclassed by developers wishing to adapt the request to a Servlet.
|
Modifier and Type | Method and Description |
---|---|
ServletRequest |
ServletRequestWrapper.getRequest()
Return the wrapped request object.
|
ServletRequest |
AsyncContext.getRequest()
Gets the request that was used to initialize this AsyncContext
by calling
startAsync() or
startAsync(ServletRequest, ServletResponse) . |
ServletRequest |
ServletRequestEvent.getServletRequest()
Returns the ServletRequest that is changing.
|
ServletRequest |
AsyncEvent.getSuppliedRequest()
Gets the ServletRequest from this AsyncEvent.
|
Modifier and Type | Method and Description |
---|---|
void |
AsyncContext.addListener(AsyncListener listener,
ServletRequest servletRequest,
ServletResponse servletResponse)
Registers the given
AsyncListener with the most recent
asynchronous cycle that was started by a call to one of the
startAsync() methods. |
void |
FilterChain.doFilter(ServletRequest request,
ServletResponse response)
Causes the next filter in the chain to be invoked, or if the calling filter is the last filter
in the chain, causes the resource at the end of the chain to be invoked.
|
void |
Filter.doFilter(ServletRequest request,
ServletResponse response,
FilterChain chain)
The
doFilter method of the Filter is called by the
container each time a request/response pair is passed through the
chain due to a client request for a resource at the end of the chain. |
void |
RequestDispatcher.forward(ServletRequest request,
ServletResponse response)
Forwards a request from
a servlet to another resource (servlet, JSP file, or
HTML file) on the server.
|
void |
RequestDispatcher.include(ServletRequest request,
ServletResponse response)
Includes the content of a resource (servlet, JSP page,
HTML file) in the response.
|
boolean |
ServletRequestWrapper.isWrapperFor(ServletRequest wrapped)
Checks (recursively) if this ServletRequestWrapper wraps the given
ServletRequest instance. |
abstract void |
GenericServlet.service(ServletRequest req,
ServletResponse res)
Called by the servlet container to allow the servlet to respond to
a request.
|
void |
Servlet.service(ServletRequest req,
ServletResponse res)
Called by the servlet container to allow the servlet to respond to
a request.
|
void |
ServletRequestWrapper.setRequest(ServletRequest request)
Sets the request object being wrapped.
|
AsyncContext |
ServletRequestWrapper.startAsync(ServletRequest servletRequest,
ServletResponse servletResponse)
The default behavior of this method is to invoke
startAsync(ServletRequest, ServletResponse)
on the wrapped request object. |
AsyncContext |
ServletRequest.startAsync(ServletRequest servletRequest,
ServletResponse servletResponse)
Puts this request into asynchronous mode, and initializes its
AsyncContext with the given request and response objects. |
Constructor and Description |
---|
AsyncEvent(AsyncContext context,
ServletRequest request,
ServletResponse response)
Constructs an AsyncEvent from the given AsyncContext, ServletRequest,
and ServletResponse.
|
AsyncEvent(AsyncContext context,
ServletRequest request,
ServletResponse response,
Throwable throwable)
Constructs an AsyncEvent from the given AsyncContext, ServletRequest,
ServletResponse, and Throwable.
|
ServletRequestAttributeEvent(ServletContext sc,
ServletRequest request,
String name,
Object value)
Construct a ServletRequestAttributeEvent giving the servlet context
of this web application, the ServletRequest whose attributes are
changing and the name and value of the attribute.
|
ServletRequestEvent(ServletContext sc,
ServletRequest request)
Construct a ServletRequestEvent for the given ServletContext
and ServletRequest.
|
ServletRequestWrapper(ServletRequest request)
Creates a ServletRequest adaptor wrapping the given request object.
|
Modifier and Type | Interface and Description |
---|---|
interface |
HttpServletRequest
Extends the
ServletRequest interface to provide
request information for HTTP servlets. |
Modifier and Type | Class and Description |
---|---|
class |
HttpServletRequestWrapper

that can be subclassed by developers wishing to adapt the request to a
Servlet.
|
Modifier and Type | Method and Description |
---|---|
void |
HttpFilter.doFilter(ServletRequest req,
ServletResponse res,
FilterChain chain)
The
doFilter method of the Filter is called by the
container each time a request/response pair is passed through the
chain due to a client request for a resource at the end of the chain. |
void |
HttpServlet.service(ServletRequest req,
ServletResponse res)
Dispatches client requests to the protected
service method. |
