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 name Context initialization parameter name of the configuration setting
Returns: The java.lang.Object associated with the configuration setting identified by name, or null if it is not defined.
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: pc Page context in which the configuration variable is to be looked up name Configuration variable name scope Scope in which the configuration variable is to be looked up
Returns: The java.lang.Object associated with the configuration variable, or null if it is not defined.
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: request Request object in which the configuration variable is to be looked up name Configuration variable name
Returns: The java.lang.Object associated with the configuration variable, or null if it is not defined.
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 to be looked up name Configuration variable name
Returns: 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.
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: context Servlet context in which the configuration variable is to be looked up name Configuration variable name
Returns: The java.lang.Object associated with the configuration variable, or null if it is not defined.
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.
Parameters: pc Page context from which the configuration variable is to be removed name Configuration variable name scope Scope from which the configuration variable is to be removed
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.
Parameters: request Request object from which the configuration variable is to be removed name Configuration variable name
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.
Parameters: session Session object from which the configuration variable is to be removed name Configuration variable name
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.
Parameters: context Servlet context from which the configuration variable is to be removed name Configuration variable name
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.
Parameters: pc Page context in which the configuration variable is to be set name Configuration variable name value Configuration variable value scope Scope in which the configuration variable is to be set
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.
Parameters: request Request object in which the configuration variable is to be set name Configuration variable name value Configuration variable 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.
Parameters: session Session object in which the configuration variable is to be set name Configuration variable name value Configuration variable 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.
