Hi all,

I'm new to hibernate and have been working through the tutorial and have encountered a problem which i fear is something really basic.

I am currently at the loading & storing objects section. When i use ant (ant run -Daction=store) on my app it seems to build ok but there are warnings. Also i do not get any indication that the Event was INSERTed t(i.e. no.... [java] Hibernate: insert into EVENTS (EVENT_DATE, title, EVENT_ID) values (?, ?, ?))


The output from the run is.....

Any help would be appreciated.
Thank you.

That's not a warning, that's a fatal error. There's no hibernate jar (hibernate2.jar or hibernate3.jar, as appropriate) on your classpath. Odd, because almost every other jar every written is there :)

Hi tenwit, thank you for your help.

I have now added hibernate3.jar to the CLASSPATH....

CLASSPATH
/root/hibernate-3.0/hibernate3.jar:/opt/ant/lib/ant-antlr.jar:/root/JUnit/junit3.8.1/junit.jar

Unfortunately i am still getting an error as follows...
Any Ideas?
Thanks again.

org.hibernate.Session is in hibernate3.jar too.
There still seems to be a problem with your classpath.

"gnu.gcj.runtime"

Use a real Java.
