Обсуждение: jdbc problems with tomcat
Hello to everybody,
I am running postgresquel 6.5.3 and tomcat 4.0.
Everything works fine when I access databases from servlets or JSP but I
can't authenticate users with JDBCRealms in tomcat using postgresql
databases.
If I try to start Tomcat I get this error from the JDBC driver. I am
using the driver jdbc6.5-1.2.jar

Is there a way to use Postgresql in JDBRealms?
Thanks in advance

Francesco I'm successfully using Postgresql 7.1.2 and Tomcat 4.0. I couldn't tell you why mine works and yours doesn't, but it may be worth upgrading your copy of Postgresql.

Francesco, It is interesting to note that you are using the latest version of tomcat (4.0), but a version of postgres that is 3 years old. You really need to upgrade postgres to 7.1 (or if you wait a few weeks to 7.2). thanks, --Barry Francesco Lunelli wrote: > Hello to everybody, > I am running postgresquel 6.5.3 and tomcat 4.0. > Everything works fine when I access databases from servlets or JSP but I > can't authenticate users with JDBCRealms in tomcat using postgresql > databases. > If I try to start Tomcat I get this error from the JDBC driver.
