The anchor tag dsp:a lets you set a property on activation of the hyperlink:
<dsp:a href="url" bean="property-spec"source-spec">link-text</dsp:a>
where source-spec specifies the source value in one of the following ways:
beanvalue=property-specparamvalue=param-namevalue=value
For example:
<dsp:a href="page2.jsp" bean="/samples/Student_01.name" value="Ron"> If your name is Ron, click here! </dsp:a>
When this link is clicked, the property Student_01.name is set to Ron before the browser opens the link.
Note: This technique is valid only if the destination URL specifies a JSP in the same Web application; see dsp:a for a complete listing of its attributes.
