RE: getResourceAsStream and relative paths in web.xml
Howdy,
*But* this did not work, which I guess is a relative issue:
...
public void init(ServletConfig config) throws ServletException {
super.init(config);
try {
this.passwordFile = config.getInitParameter( passwordFile
);
this.passwords = new Properties();
passwords.load( new FileInputStream( passwordFile );
} catch( IOException ioe ) {}
}
...
Can someone summarize why the second example does not work with
relative
paths? I understand why the first one does.
Two reasons, one certain and one possible:
1. Certainly, using a FileXXX class will attempt to interpret the init
parameter value (/WEB-INF...) is an absolute path, because that's how
absolute paths are defined for files.
2. If you happen to be running from a packed .war file, you may NPE when
trying to construct a FileInputStream as File-based accesses are not a
given in a packed .war.

RE: getResourceAsStream and relative paths in web.xml
Howdy,
Oh and by the way, it's a good habit to override the init() method for a
servlet rather than the init(ServletConfig) one. Simply so you don't
accidentally forget to call super(config).

1. Certainly, using a FileXXX class will attempt to interpret the init parameter value (/WEB-INF...) is an absolute path, because that's how absolute paths are defined for files. Thank you again Yoav. The recommendation then is to skip trying to use a FileInputStream (because the String provided is absolute to the file system not servlet context, i.e. /WEB-INF/lib/x.props is intepreted as from root on *NIX and C:\ on Windoze). Additionally config.getServletContext().getResourceAsStream( file ) works in and out of war packages.
