And becouse You asked:
I have the following problems with Tomcat 5:

1. Logging: it is clear for me that different versions of
commons_logging.jar or log4j.jar ar creating the problem, I have this
conclusion after a few days of investigations, but I have no solutions yet.
The error mesage is the following one:

log4j:WARN No appenders could be found for logger
(org.apache.catalina.session.ManagerBase).
log4j:WARN Please initialize the log4j system properly.

I studied all the documentation on the net, I configured the web.xml and
log4j.properties as well.

2. JasperReports not working, even in the bookstore example. The error is
the following one:

Error:
  a.. null



I tested this with hsqldb, the database works with other jsp pages, only
with JasperReports not. The results are the same with MySQL, the other jsp
pages are working good. In this weekend I intend to test all these things
with Oracle.

I am going to put out to the web an accounting application based on dbforms
(a wonderful library), if somebody is interested to see it, I shall send the
adress.

With respect
Varga Sandor.
