JavaSercer Pages import No default A Java import (Video web hosting)
JavaSercer Pages import No default A Java import declaration, i.e., a comma-separated list of fully qualified class names or package names followed by .* (for all public classes in the package). info No default Text that a web container may use as a description of the page in its administration user interface. isErrorPage false Set to true for a page that is used as an error page, to make the implicit exception variable available to scripting elements. Use false for regular JSP pages. isThreadSafe true Set to true if the container is allowed to run multiple threads through the page (i.e., lets the page serve parallel requests). If set to false, the container serializes all requests for the page. It may also use a pool of page implementation class instances to serve more than one request at a time. The recommendation is to always use true, and handle multithread issues by avoiding JSP declarations and ensuring that all objects used by the page are thread-safe. language java Defines the scripting language used in the page. session true Set to true if the page should participate in a user session. If set to false, the implicit session variable is not available to scripting elements in the page. A translation unit (the JSP source file and any files included via the include directive) can contain more than one page directive, as long as there is only one occurrence of an attribute, with the exception of the import attribute. If multiple import attribute values are used, they are combined into one list of import definitions. Example: <%@ page language="java" contentType="text/html;charset=Shift_JIS"%> <%@ page import="java.util.*, java.text.*" %> <%@ page import="java.sql.Date" %> A.1.3 taglib Directive Declares a tag library, containing custom actions, that is used in the page. The taglib directive supports the attributes described in Table A.3. Table A.3, taglib Directive Attributes Attribute Name Default Description prefix No default Mandatory. The prefix to use in the action element names for all actions in the library. uri No default Mandatory. Either a symbolic name for the tag library defined in the web.xml file for the application, or a page-relative or context-relative URI path for the library’s TLD file or JAR file. Example: <%@ taglib uri="/orataglib" prefix="ora" %> page 261
