URL-pointing problem
Hello,
having a bit of a problem here.
We have deployed a web application on our server by putting it in the
webapps directory, this makes it appear at a URL like
http://mjau.com/pub_db. Now we want to change the URL for this webapp to
something else, (in this case http://mjau.com/publications).
Currently we've tried messing around with URL-mapping
in /tomcat5/conf/web.xml and /tomcat5/webapps/WEB-INF/web.xml.
We've tried to use the servlet-mapping directive in our web data
xml-files, but it seems that the servlet is implicitly defined when
putting the webapp in the webapps directory, because we have no servlet
section in our web data xml-files. But things work anyway.
But when we try to define our own servlet section, it won't work.
We are running Tomcat 5.0.30, Java 5.0, on a Debian Etch server.
This is what we've tried to do in the /tomcat5/conf/web.xml:
<servlet>
<servlet-name>pubdb</servlet-name>
<servlet-class>
pubdb
</servlet-class>
</servlet>-->
<!--<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/publications/*</url-pattern>
</servlet-mapping>-->
</web-app>
Anyone have a clue what we're doing wrong?

The simplest thing to do is to stop Tomcat, rename the pub_db
subdirectory in webapps to publications and then restart Tomcat.
If you have a pub_db.xml file in Tomcat5/conf/ then you'll have to
rename that to publications.xml.
Let me know if you can't rename the directory for some reason and I'll
give you a more complex solution.
regards,
Richard

Oops :-).
You might like to look at the servlet context's methods for fetching
resources (getResource and getResourceAsStream, I think). They make the
file locations relative to the servlet, wherever it's deployed.

^__^
Our webapp had hardcoded paths in it, now we "just" have to grep them
all and replace them.
Thanks y'all!

So what's causing the NPE then? :-)

We tried changing the folder name, however that makes our servlet crash.
Couldn't find content.xml though; only admin.xml and manager.xml resides
under /conf/
.
The following error message is returned when trying to run the app:

note
(We might get a response that says "well it's a badly coded app then" :)
however, since our java skills really aren't up to par, it would be
great if there was an easier solution rather than rewriting the app.)

There's a difference between webapp names and servlet names. You want
to change the webapp's name. To do that, just change the name of the
webapp in the webapps folder ie pub_db -> publications or pub_db.war ->
publications.war. You may have to make a similar name change to the
context.xml file in conf/Catalina/localhost and then restart tomcat.
