find
public static Object find(PageContext pc,
String name)
Finds the value associated with a specific configuration setting
identified by its context initialization parameter name.
For each of the JSP scopes (page, request, session, application),
get the value of the configuration variable identified by
name
using method
get(). Return as soon as a non-null value is
found. If no value is found, get the value of the context initialization
parameter identified by
name.
pc
- Page context in which the configuration setting is to be
searchedname
- Context initialization parameter name of the configuration
setting
- The java.lang.Object associated with the configuration
setting identified by name, or null if it is not defined.
get
public static Object get(HttpSession session,
String name)
Looks up a configuration variable in the "session" scope.
The lookup of configuration variables is performed as if each scope
had its own name space, that is, the same configuration variable name
in one scope does not replace one stored in a different scope.
session
- Session object in which the configuration variable is to
be looked upname
- Configuration variable name
- The java.lang.Object associated with the configuration
variable, or null if it is not defined, if session is null, or if the session
is invalidated.
get
public static Object get(PageContext pc,
String name,
int scope)
Looks up a configuration variable in the given scope.
The lookup of configuration variables is performed as if each scope
had its own name space, that is, the same configuration variable name
in one scope does not replace one stored in a different scope.
pc
- Page context in which the configuration variable is to be
looked upname
- Configuration variable namescope
- Scope in which the configuration variable is to be looked
up
- The java.lang.Object associated with the configuration
variable, or null if it is not defined.
get
public static Object get(ServletContext context,
String name)
Looks up a configuration variable in the "application" scope.
The lookup of configuration variables is performed as if each scope
had its own name space, that is, the same configuration variable name
in one scope does not replace one stored in a different scope.
context
- Servlet context in which the configuration variable is
to be looked upname
- Configuration variable name
- The java.lang.Object associated with the configuration
variable, or null if it is not defined.
get
public static Object get(ServletRequest request,
String name)
Looks up a configuration variable in the "request" scope.
The lookup of configuration variables is performed as if each scope
had its own name space, that is, the same configuration variable name
in one scope does not replace one stored in a different scope.
request
- Request object in which the configuration variable is to
be looked upname
- Configuration variable name
- The java.lang.Object associated with the configuration
variable, or null if it is not defined.
remove
public static void remove(HttpSession session,
String name)
Removes a configuration variable from the "session" scope.
Removing a configuration variable is performed as if each scope had
its own namespace, that is, the same configuration variable name in one
scope does not impact one stored in a different scope.
session
- Session object from which the configuration variable is
to be removedname
- Configuration variable name
remove
public static void remove(PageContext pc,
String name,
int scope)
Removes a configuration variable from the given scope.
Removing a configuration variable is performed as if each scope had
its own namespace, that is, the same configuration variable name in one
scope does not impact one stored in a different scope.
pc
- Page context from which the configuration variable is to be
removedname
- Configuration variable namescope
- Scope from which the configuration variable is to be
removed
remove
public static void remove(ServletContext context,
String name)
Removes a configuration variable from the "application" scope.
Removing a configuration variable is performed as if each scope had
its own namespace, that is, the same configuration variable name in one
scope does not impact one stored in a different scope.
context
- Servlet context from which the configuration variable is
to be removedname
- Configuration variable name
remove
public static void remove(ServletRequest request,
String name)
Removes a configuration variable from the "request" scope.
Removing a configuration variable is performed as if each scope had
its own namespace, that is, the same configuration variable name in one
scope does not impact one stored in a different scope.
request
- Request object from which the configuration variable is
to be removedname
- Configuration variable name
set
public static void set(HttpSession session,
String name,
Object value)
Sets the value of a configuration variable in the "session" scope.
Setting the value of a configuration variable is performed as if
each scope had its own namespace, that is, the same configuration
variable name in one scope does not replace one stored in a different
scope.
session
- Session object in which the configuration variable is to
be setname
- Configuration variable namevalue
- Configuration variable value
set
public static void set(PageContext pc,
String name,
Object value,
int scope)

variable name in one scope does not replace one stored in a different
scope.

- Configuration variable namevalue
- Configuration variable valuescope
- Scope in which the configuration variable is to be set
set
public static void set(ServletContext context,
String name,
Object value)

Setting the value of a configuration variable is performed as if
each scope had its own namespace, that is, the same configuration
variable name in one scope does not replace one stored in a different
scope.
