Thank you Chong for your reply,
Perhaps I need to clarify, I have downloaded the FirebirdSQL-1.0.0
(Jaybird) driver and am following the directions in the FAQ file, with
modifications to the connection url for the fact that I am on a windows
system. As far as the type 4 driver that is included (that you
mentioned), I do not see any info other than release notes (which seem
to indicate the driver I downloaded and installed are same as the one
included) the information in the release are very general in nature and
not help in the way of installation and testing. The Jaybird driver is
the one I wish to use due to the connection pooling feature, I am
following the information in the Tomcat "jndi-datasource" howto in the
Tomcat docs, although as indicated in my previous email, I am having
little luck. In addition, I want to confirm that I have placed all
relevant .jars in the commom/lib directory. Again thank you for your
previous response - any additional assistance will be very helpful.
Thank you,
Rob

Hello Rob !
I'm not sure if you are aware : the Firebird database comes with 2 JDBC
"flavors", a Type 4 JDBC driver (which is a separate download) and
Interclient (which is really more of a JDBC mediation component). The
configuration for Interclient is covered in this link :
http://www.kpi.com.au/interbase/index.jsp while the configuration for
the Type 4 JDBC driver is in the README file that comes with the driver
download. Depending on which driver you use, the configuration is *very*
different! If you are following the MySQL examples, you should use the
Type 4 driver.
Second, make sure that your JDBC driver is in your CLASSPATH and that
Tomcat can "see" it. That is, either point to it explicitly in your
CLASSPATH, or save the jar file into $TOMCAT_HOME/common/lib.

Hey guys, I am hoping I could get some help with this issue. The
research I have done online reveals this error with several databases
although I have yet to find a actionable answer nor anything firebird
spoecific. I am attempting to connect Firebird to Tomcat based on the
MYSQL example in the Tomcat Docs and through the datasource setup in
the administration console. I have attempted to include all relevant
data to show the activity on my server, including the log, the
example code, and the relevant server.xml code.
I appreciate all help that you can offer.
