How to read a external file after deployment? [message #885626]

Dear community,
I have an application built on RAP. In my application, I have a list of Strings. I want to have content of these strings configurable from an external file (e.g xml file) when user enter website. My app will read content of that file and the website will display the respective content (it's kind of config file).
For example, the path to website is as following:
{TOMCAT_HOME}/webapps/{my_app}/WEB-INF
After deployment, I want to add a file .xml to category WEB_INF, then my website will read the content of that file.
My question is how I can know the path of my app in webserver after deployment, because eclipse wrap the whole project into bundle. Or is there any other way to solve my problem?
Thank you very much!

RWT.getRequest().getServletContext().getRealPath("/") will give you the absolute path of your installation. I guess this solves your issue. You just need make sure of one thing that you access RWT.getRequest with a http request.

Hi Avrajit,
Thanks for your answer.
I followed your suggestion but I got the error as following:

Could not create the view: javax.servlet.http.HttpServletRequest.getServletContext()Ljavax/servlet/ServletContext;

The error line is in the area where I initiate layout of a view.
I got null here:

RWT.getRequest().getServletContext().getRealPath("/")

Currently, you can only access the context location using internal API:

RWTFactory.getConfiguration().getContextDirectory()

Feel free to open a feature request [1] for a public API and explain why
it is needed.
