[dexter195]

hi,
ive reciently started using hibernate, the object oriented/relational database api.
ive gone through the tutorial on the hibernate site

http://www.hibernate.org/hib_docs/reference/en/pdf/hibernate_reference.pdf

its suppose to allow you to set it up in a tomcat server.

i keep getting the following errors, ive set it up according to the tutorial.

log4j:WARN No appenders could be found for logger (net.sf.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.

It looks like it is trying to connect to a DB that it is not able to find. Are you trying to use the hibernate connection pooling? I think the example may use HSSQL. You may want to make sure the DB is configured OK.

i found a tutorial on this site that help solve all my problems.

http://caveatemptor.hibernate.org/downloads/caveatemptor-0.9.5.zip

it shows how to set up hibernate properly and it has the connection settings for a whole host of different databases. you will need to be familiar with ant and junit though.
