Hi friends.

I'm getting the following:

This is my cfg:

and this is my called class:

I'm not using webserver, just trying to validade data with sql server 2000.

The database is called HIBERNA and the table amigo.

Can somebody help me, please?

It looks like you have a problem with the log, and not with hibernate.
do you have all the jars in the right place?

Thanks for your attention, Issahar.

I have all my .jar inside the Eclipse Project Hiberna_SQL, addeds with the Add External Jars option, including the msutil.jar, mssqlserver.jar and msbase.jar i got from MS. I hope be that. My log config is

log4j.rootLogger=INFO, dest1

log4j.appender.dest1=org.apache.log4j.ConsoleAppender
log4j.appender.dest1.layout=org.apache.log4j.PatternLayout
log4j.appender.dest1.layout.ConversionPattern=%d %-5p %-5c{3} %x -> %m%n

#log4j.appender.dest2=org.apache.log4j.RollingFileAppender
#log4j.appender.dest2.File=bridge.log

#log4j.appender.dest2.MaxFileSize=100KB
#Keep one backup file
#log4j.appender.dest2.MaxBackupIndex=3

#log4j.appender.dest2.layout=org.apache.log4j.PatternLayout
#log4j.appender.dest2.layout.ConversionPattern=%d [%t] %-5p %-5c{3}(%L) %x -> %m%n

maybe the name gets in the way?
You said you don't use any server, so you don't use jndi name, and also you gave all the jdbc data, so there's no need for jndi SessionFactory.
try removing the attribute, and see if it works.

Jus.

I still thinks it is something to do with the log...

well, i'm new in hibernate and have no knowledgment about it. I got an example from Javafree and did everything. It was working until i try to connect to Oracle. It dont show any error but the table is not updated. After, i get the sqlserver driver and create another project (all the 3 are the same, changing only the hibernate.cfg.xml for each one). Now, none is working and each one return to me different erroes. I ask, really need i a log4j.properties even if i dont use a webserver like tomcat?

No you don't, but you have to know enough about such a trivial thing as logging to use this software. Try Google as well.
