Btw, the realms.xml path is already configured within 
local/apache-tomcat-5.5.20/webapps/yanel/WEB-INF/classes/yanel.xml

re the working/temp dir I guess you mean with

File dir = (File) getServletContext()

     .getAttribute(
     "javax.servlet.context.tempdir");


right?

if the paths of the realms are wrong within classes/realms.xml then it 
doesn't start either ;-)

I think the question is what situations is this directory deleted.

Let me give it a try ...
