Fw: Accessing properties values from VTL

[Peter Anning <pe...@bigfoot.com>]

Hi,

I have a value in the properties file (velocity.properties)

tools.view.servlet.layout.directory = decorators/

is there a way to reference this value from a VTL (.vm) file

e.g. how to make this reference

#set($layout_dir = <tools.view.servlet.layout.directory> )

Thanks and Regards
Peter

at the present, this value is not automatically placed in the context for you.
i think the simplest way for you to get it would be to extend the
VelocityLayoutServlet and add it to the servlet context attributes during the
servlet's init:  e.g.

public class MyServlet extends VelocityLayoutServlet {

    public void init(ServletConfig config) throws ServletException {
        super.init(config);
        String layoutdir = Velocity.getString(PROPERTY_LAYOUT_DIR,
DEFAULT_LAYOUT_DIR);
        config.getServletContext().setAttribute("layout_dir", layoutdir);
    }

}

if you feel that adding access to certain/all property values from VTL is a
useful thing in general, i would suggest adding an enhancement request to
Bugzilla along with a simple explanation of what this would be used for.  such
a change won't make it into the 1.1 release, but might be worth considering
for 1.2.
