I'm using Struts 1.3.9, with Tiles. I've one action that calls to a
definition
struts-config.xml
<action path="/customer/verGraphPortfolio"
forward="verGraphPortfolio.pantalla"/>
riles-def..xml
<definition name=" verGraphPortfolio.pantalla"
controllerClass="com.bpi.isis.customer.web.vista.PortfolioValGraphContro
ller"/>
In the PortfolioValGraphController I have this code
....
response.setHeader("Content-Disposition", "inline");
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Cache-Control", "no-store");
response.setHeader("Cache-Control", "must-revalidate");
response.getOutputStream().write(baos.toByteArray());
response.getOutputStream().flush();
response.getOutputStream().close();
response.setStatus(HttpServletResponse.SC_OK);
baos.close();
baos = null;
.....
If I don't put the path attribute in the definition, the controller is
not invocated and the user doesn't see the image. In the logs your can
see this:

Do I need to put a JSP in the path? An empty JSP? Is there any way to
avoid this?
