RE: Relative Servlet Path

[Chuck Carson]

I am confused.

I merely want to reference a file from within a servlet(s). I want to
keep my apps transportable so I have a var like this:

String myVar = "db/config.dat";

Where is it looking for this file. If the servlet is here:
$TCAT_HOME/ROOT/WEB-INF/classes/MyServlet, where will it look for the db
directory?

Thanks,
CC

Well, if you are talking about context.getRealPath("/"), that points to
the 
root of your webapp.  If you were to append your "db/file.dat" to that,
you 
would be looking for it in:

MyContext/
db/file.dat
WEB-INF/web.xml

I assume you want your db file hidden from view so I'd do:

getRealPath("/WEB-INF/db")

Note that this is no relative to the current servlet.  It is relative to

the current context.  Also note that getRealPath("/") will return "null"
if 
your app is deployed directly from a .war file and not and expanded 
directory, so be careful about this usage.

Relative Servlet Path

[Chuck Carson]

 
If I have a servlet, say ROOT/WEB-INF/classes/MyServlet, what would be
the relative path for this servlet. ie: If I have a variable as such:
 
String myconfig = "db/file.dat";
 
What is this path relatvie to, would it be the same directory as the
servlet, thus I would create ROOT/WEB-INF/classes/db ?
 
Sorry if this is newbie, I have only been using tomcat for 2 weeks.
 
Thanks,
Chuck
