Hi,
Thanks for the info.
Apparently, the database was not set correctly.
After correcting the previous problem, I am able to login. The log shows
the correct authentication with no errors.
Yet, I not getting anything after the login. the web page is clear, in
stead of taking me to the next page, by design.
the top url address is like:
http://localhost/login/j_security_check
any help, suggestion, or comment would be nice.
Thanks,
James

The JDBCRealm does two things:
1) Authenticates the user (by checking password)
2) Authorizes the user (by checking roles)
The logs would seem to imply the JDBC driver is blowing up creating the
prepared statement in the second step (ie reading from the roles table).
I think Tim is right - he usually is - that there is a config problem
with the db or the connection to the db.
A quick google later:
