I hope this is a trivial problem that someone can help me with...
I have been running a web app, built using Netbeans with Tomcat for
months now. The system uses Hibernate for database access.
This week, I erased and rebuilt my desktop system - moved it from Fedora
8 to Fedora 10. I re-installed Netbeans and Tomcat.
Netbeans rebuilds my program without any problem, but when I try to
connect to the database (my login screen comes up fine)
I get this:
*Exception Handler *
*Description: * An unhandled exception occurred during the execution of

and it goes on for several pages. Netbeans did not complain about
missing libraries or missing classes. I have just downloaded the latest
version of Hibernate and updated my libraries.
In /usr/local/Tomcat, I find this:
[nco...@nbc-penguin Tomcat]$ find . |grep hibernate
./webapps/NCAT/WEB-INF/lib/hibernate-core.jar
./webapps/NCAT/WEB-INF/lib/hibernate-annotations.jar
./webapps/NCAT/WEB-INF/lib/hibernate-commons-annotations.jar
./webapps/NCAT/WEB-INF/lib/hibernate-entitymanager.jar
So the entity-manager is there as far as I can tell.
Can someone tell me what I need to do (or look for) to fix this problem??
Much obliged,
nbc
