Hi Zoltan,
if you want to create an image on the fly, you may want to use the
DirectResponseLayout template within an action class (I think this
was just recently discussed here). We recently converted our Turbine-
based secondary servlets to action classes by simply extending the
following class instead of a copy of BaseTurbineServlet that we had
moved into our packages:
public abstract class AbstractDirectAction extends VelocityAction {
public void doPerform(RunData data, Context ctx) throws Exception {
data.declareDirectResponse();
data.setLayout("DirectResponseLayout");
processRequest(data);
}
public abstract void processRequest(RunData data) throws
ServletException,
IOException;
}
see also http://wiki.apache.org/jakarta-turbine/Turbine2/
VelocityOnlyLayout
Don't forget to set the headers correctly in your subclass'
processRequest method. In it, just get the HttpServletResponse object
from the RunData object and from it, get the outputstream to write to.
good luck,
h.

Hello All,
I would like to exec a screen which is a descendant of RawScreen.
The module is in modules/screens named Captcha.java.
It provide a gif for a form in any vm.
I tried to link it :
$link.setScreen('Captcha') which is processed like this:
<img src="/portal/app/screen/Captcha" border="0">
but it doesn' t work:(
Seems to be Turbine using Default template name if link doesn't
have 'template' in params, and doesn' t find screen.
Are there any TR.prop settings to configure it, or any solution to use
RawScreen ?
I am usinng Turbine 2.3.2
