Source: Internet
Author: User

An action instruction differs from a compilation instruction in that it notifies the Servlet engine of processing messages, while an action instruction is only a script action at run time. Compilation directives work when compiling a JSP into a Servlet: processing instructions are usually replaced with Java scripts and are standardized for JSP scripts.

JSP action instructions are mainly the following seven:

Jsp:forward

Performs a page shift and forwards the requested processing to the next page.

Jsp:param

Used to pass parameters and must be used with other support parameter curvature labels.

Jsp:include

Used to dynamically introduce a JSP page.

Jsp:p1ugin

For downloading JavaBean or applets to client execution.

Jsp:usebean

Use JavaBean.

Jsp:setproperty

Modifies the property value of the JavaBean instance.

Jsp:getproperty

Gets the property value of the JavaBean instance.
