Opening files, relative paths

[Allen Walker <aw...@mail.utexas.net>]

What I'm doing is this:

java.io.File xmlfile = new java.io.File (path_to_file).

Problem is, I don't know how to specify the var path_to_file other than the 
absolute path. I find the relative path to be /jakarta-tomcat/bin, but this 
obviously isn't where I wish to place my app config files etc. Coding 
absolute path's is troublesome due to deployment issues. Any help appreciated.

Thanks

This approach works -- but *only* if your web application is expanded into
a real directory (instead of being run directly from the WAR file).  To
access a properties file within the WAR, no matter what your servlet
container does, do something like this:

	InputStream is =
	  getServletContext().getResourceAsStream("/WEB-INF/web.xml");

which will let you read the web application's deployment descriptor.  You
can use any context-relative path that you wish.

You can use the ServletContext's getRealPath( context_relative_path )
method. E.g.: servletContext.getRealPath( "/WEB-INF/myconf.xml" ).
