servlet url at init time

[jo...@bnpparibas.com]

Hello all,

I would like to know the URL of a servlet _in its init method_:
I need it to know how it is called without having to tell it via a
config file...
I know how to get it when dealing with doGet or doPost, but can't
find any api at init time :(

did I miss something?

thanks

There is no such API, but see below for part of the answer.

Keep in mind that a servlet doesn't have to have "a" URL -- you can map as
many different URL patterns as you like to it.  Therefore, if you *really*
want to know, you can use an XML parser to read the "/WEB-INF/web.xml"
resource and figure them all out.  You can find out your own
<servlet-name> (in servlet 2.3 at least) from the ServletConfig object, so
it's just a matter of looking for all the <url-pattern> values that map to
this name.

This still only tells you the context-relative part of the URL -- the
context path is not visible until a request comes in.
