| Method Summary | |
| 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(). | | public static Object | get(PageContext pc, String name, int scope)
Looks up a configuration variable in the given scope. | | public static Object | get(ServletRequest request, String name)
Looks up a configuration variable in the "request" scope. | | 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.
Parameters:
session - Session object in which the configuration variable is tobe looked up
Parameters:
name - Configuration variable name The java.lang.Object associated with the configurationvariable, or null if it is not defined, if session is null, or if the sessionis invalidated. | | public static Object | get(ServletContext context, String name)
Looks up a configuration variable in the "application" scope. | | public static void | remove(PageContext pc, String name, int scope)
Removes a configuration variable from the given scope. | | public static void | remove(ServletRequest request, String name)
Removes a configuration variable from the "request" scope. | | public static void | remove(HttpSession session, String name)
Removes a configuration variable from the "session" scope. | | public static void | remove(ServletContext context, String name)
Removes a configuration variable from the "application" scope. | | public static void | set(PageContext pc, String name, Object value, int scope)
Sets the value of a configuration variable in the given scope. | | public static void | set(ServletRequest request, String name, Object value)
Sets the value of a configuration variable in the "request" scope. | | public static void | set(HttpSession session, String name, Object value)
Sets the value of a configuration variable in the "session" scope. | | public static void | set(ServletContext context, String name, Object value)

in SQL query result
|
| find | | public static Object find(PageContext pc, String name)(Code) | | 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.
Parameters:
pc - Page context in which the configuration setting is to be searched
