JSP common actions

Jsp:include dynamic inclusion;

Jsp:forward forwarding;

Jsp:usebean instantiate Bean object;

Jsp:setproperty Setting a property value

Jsp:getproperty Get a property value

Jsp:param dynamic transmission parameters;

Jsp:plugin Generating a plugin

Jsp:usebean instantiation of an object;

Persondao dao = new Persondao ();

In a JSP page, this code can be "somewhat" equivalent to the following code (scope scope concept)

<jsp:usebean id= "DAO" class= "Com.testing.dao.PersonDao" ></jsp:useBean>

Jsp:setproperty set a property value that must be used in conjunction with Jsp:usebean;

<jsp:usebean id= "Personbean" class= "Com.testing.bean.PersonBean" ></jsp:useBean>

<jsp:setproperty property= "A" name= "Personbean" param= "B"/>

Equivalent to the following code:

Personbean Personbean = new Personbean ();

String B = Request.getparameter ("B");

Personbean.seta (b);
