public class VelocityViewTag
- extends javax.servlet.jsp.tagext.BodyTagSupport
This tag enables use of Velocity and VelocityTools within JSP files and tags.
This makes it trivial to render embedded VTL (Velocity Template Language)
or include a separate Velocity template within a JSP using the current
page context. This also automatically provides the typical
VelocityView
toolbox support, much like the VelocityViewServlet
and VelocityLayoutServlets have. In fact, this will by default share
the VelocityView
instance used with those servlets. This allows
for consistent configuration and shared resources (better performance).
