All Classes and Interfaces
Class
Description
An encapsulation of the evaluation of the body of an action so it is
available to a tag handler.
The BodyTag interface extends IterationTag by defining additional
methods that let a tag handler manipulate the content of evaluating its body.
A base class for defining tag handlers implementing BodyTag.
Creates a cookie, a small amount of information sent by a servlet to
a Web browser, saved by the browser, and later sent back to the server.
A filter is an object than perform 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
Filters perform filtering in the
doFilter method.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.
A filter configuration object used by a servlet container
used to pass information to a filter during initialization.
Defines a generic, protocol-independent
servlet.
The HttpJspPage interface describes the interaction that a JSP Page
Implementation Class must satisfy when using the HTTP protocol.
Provides an abstract class to be subclassed to create
an HTTP servlet suitable for a Web site.
Extends the
ServletRequest interface
to provide request information for HTTP servlets.Provides a convenient implementation of the HttpServletRequest interface that
can be subclassed by developers wishing to adapt the request to a Servlet.
Extends the
ServletResponse interface to provide HTTP-specific
functionality in sending a response.Provides a convenient implementation of the HttpServletResponse interface that
can be subclassed by developers wishing to adapt the response from a Servlet.
Provides a way to identify a user across more than one page
request or visit to a Web site and to store information about that user.
Objects that are bound to a session may listen to container
events notifying them that sessions will be passivated and that
session will be activated.
This listener interface can be implemented in order to
get notifications of changes to the attribute lists of sessions within
this web application.
Events of this type are either sent to an object that implements
HttpSessionBindingListener when it is bound or
unbound from a session, or to a HttpSessionAttributeListener
that has been configured in the deployment descriptor when any attribute is
bound, unbound or replaced in a session.Causes an object to be notified when it is bound to
or unbound from a session.
Deprecated.
As of Java(tm) Servlet API 2.1
for security reasons, with no replacement.
This is the class representing event notifications for
changes to sessions within a web application.
Implementations of this interface may are notified of changes to the
list of active sessions in a web application.
Deprecated.
As of Java(tm) Servlet API 2.3.
The IterationTag interface extends Tag by defining one additional
method that controls the reevaluation of its body.
The JspEngineInfo is an abstract class that provides information on the
current JSP engine.
A generic exception known to the JSP engine; uncaught
JspExceptions will result in an invocation of the errorpage
machinery.
The JspFactory is an abstract class that defines a number of factory
methods available to a JSP page at runtime for the purposes of creating
instances of various interfaces and classes used to support the JSP
implementation.
The JspPage interface describes the generic interaction that a JSP Page
Implementation class must satisfy; pages that use the HTTP protocol
are described by the HttpJspPage interface.
Exception to be used by a Tag Handler to indicate some unrecoverable
error.
The actions and template data in a JSP page is written using the
JspWriter object that is referenced by the implicit variable out which
is initialized automatically using methods in the PageContext object.
A PageContext instance provides access to all the namespaces associated
with a JSP page, provides access to several page attributes, as well as
a layer above the implementation details.
Translation-time information on a JSP page.
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.
Defines methods that all servlets must implement.
A servlet configuration object used by a servlet container
used to pass information to a servlet during initialization.
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.
This is the event class for notifications about changes to the attributes of the
servlet context of a web application.
Implementations of this interface recieve notifications of
changes to the attribute list on the servlet context of a web application.
This is the event class for notifications about changes to the servlet context of a web application.
Implementations of this interface recieve notifications about changes to the servlet context of the web application they are part of.
Defines a general exception a servlet can throw when it
encounters difficulty.
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.Provides an output stream for sending binary data to the
client.
Defines an object to provide client request information to a servlet.
Provides a convenient implementation of the ServletRequest interface that
can be subclassed by developers wishing to adapt the request to a Servlet.
Defines an object to assist a servlet in sending a response to the client.
Provides a convenient implementation of the ServletResponse interface that
can be subclassed by developers wishing to adapt the response from a Servlet.
Ensures that servlets handle
only one request at a time.
The interface of a simple tag handler that does not want to manipulate its body.
Information on the attributes of a Tag, available at translation time.
The (translation-time only) attribute/value information for a tag instance.
Optional class provided by the tag library author to describe additional
translation-time information not described in the TLD.
Tag information for a tag in a Tag Library;
This class is instantiated from the Tag Library Descriptor file (TLD)
and is available only at translation time.
Translation-time information associated with a taglib directive, and its
underlying TLD file.
Translation-time validator class for a JSP page.
A base class for defining new tag handlers implementing Tag.
Variable information for a tag in a Tag Library;
This class is instantiated from the Tag Library Descriptor file (TLD)
and is available only at translation time.
The auxiliary interface of a Tag, IterationTag or BodyTag tag
handler that wants additional hooks for managing resources.
Defines an exception that a servlet or filter throws to indicate
that it is permanently or temporarily unavailable.
A validation message from a TagLibraryValidator.
Information on the scripting variables that are created/modified by
a tag (at run-time).
