Problems with running servlet_example1 on Sun J2EE 1.3 Ref. Impl.

Hello all!

I'm currently evaluating several software 'packages' which should help me in
my J2EE Presentation Layer development. One of them is Velocity...

To get more deeper in it I wanted to try the examples of the velocity
version 1.1 on the Sun J2EE 1.3 Reference Implemenation. 

For example I've build and tried to run the servlet_example1 as told in the
readme, which is quite simple...(so the possibility to make to much errors
on my side should not be to high ;-) 
I tried it on both the 1.3 Beta and the yesterday released Final
Implemention. On both it failed to work. Perhaps it has to do with the PANIC
log message on configuring AvalonLogSystem? So no there is no velocity.log
which I can provide you. The other log snipplets are at the end of the mail.


I've gone also through the mail archive but coudn't find something which
helped me to get the example to work.

Any ideas? Thank you all.

-Paolo

Looks like this directory is not writeable...

Well, the error is pretty clear...you need permission to write to that
directory.

It sounds like you have something wrong with your configuration of both your
machine as well as Velocity.
