1<jsp:getProperty name="test" property="date"/> will print the value of property.

2<jsp:useBean id="test" class="com.Example">
<jsp:setProperty name="test" property="*"/>
</jsp:useBean>

3 <jsp:setProperty name="test" property="date" param="someParam"/> gets the value of property from request parameters

4 <jsp:setProperty name="test" property="date" value="12"/> sets the value of property explicitly

5 variables declared in declaration elements are instance variable and not global variable. They seem global because all JSP requests share same instance.
