Class ValidationMessage
java.lang.Objectjavax.servlet.jsp.tagext.ValidationMessage
public class ValidationMessage
extends java.lang.Object
A validation message from either TagLibraryValidator or TagExtraInfo.
As of JSP 2.0, a JSP container must support a jsp:id attribute
to provide higher quality validation errors.
The container will track the JSP pages
as passed to the container, and will assign to each element
a unique "id", which is passed as the value of the jsp:id
attribute. Each XML element in the XML view available will
be extended with this attribute. The TagLibraryValidator
can then use the attribute in one or more ValidationMessage
objects. The container then, in turn, can use these
values to provide more precise information on the location
of an error.
The actual prefix of the
id attribute may or may not be
jsp but it will always map to the namespace
http://java.sun.com/JSP/Page. A TagLibraryValidator
implementation must rely on the uri, not the prefix, of the
id
attribute.
String | getId()- Get the jsp:id.
|
String | getMessage()- Get the localized validation message.
