can't deploy with war files

[jorge]

Hello,

When I create a application (no war file) in .../webapps/test dir, 
it works well. But if I turn it into war file, delete dir teste,
put test.jar into .../webapps and restart tomcat, I get this erro:

.java.lang.IllegalArgumentException: Document base ./../webapps/test
 does not exist or is not a readable directory

and it don't start.
I'm using tomcat 4.0.
This is a beta version of tomcat. Maybe a bug?
I have already deployed war files with tomcat 3.2. 

Thanks in advance.
