I tried the following code
String jobDataFileResourceName =
servletContext.getRealPath("")
+ "/WEB-INF" + "/jobs_" +
info.getName() + ".txt";
InputStream stream =new
FileInputStream(jobDataFileResourceName);
but I am receiving AccessControlException right now.
Caused by: java.security.AccessControlException: access denied
(java.io.FilePermission /base/data/home/apps/dddd/
