How access to servlet context parameters from birt javascript? [message #780873]

I have a report with a dynamic xml file as datasource.
This file is generated previously to launch the report and is send like a report parameter.

So I declared a datasource with target in "property binding":

"/path_to_folder_with_generated_files/data/" + params["dynamic_xml_file"].value

At this point, go all right.

But i need that "/path_to_folder_with_generated_files/data/" will be

{BIRT_VIEWER_WORKING_FOLDER} + "/data/" + params["dynamic_xml_file"].value

where {BIRT_VIEWER_WORKING_FOLDER} will be the value of this context parameter declared in web.xml deploy descriptor.

How do i access to context parameters from birt javascript?

Environment: Birt 3.7.1 deployed in Glassfish 3.1, ubuntu linux, jdk 1.6

Try:
req =reportContext.getHttpServletRequest();
sc = req.getSession().getServletContext();
//xyz = sc.getRealPath("/");
var workingpath =sc.getInitParameter("BIRT_VIEWER_WORKING_FOLDER");

This will not work in the designer but should work in the deployed
viewer. You could also use getRealPath which should work in both.
