Hi Alessandro,

How are you using this? Why are you using a JNDI resource instead of a JNDI
dataSource? What version of Tomcat, and JayBird are you using?

The parameter "charSet" is not valid for JayBird.

You may be able to change:
<parameter><name>driverName</name><value>jdbc:firebirdsql:127.0.0.1/3050:/db
/off.gdb</value></parameter

To:
<parameter><name>driverName</name><value>jdbc:firebirdsql:127.0.0.1/3050:/db
/off.gdb?&lc_ctype=ISO8859_1</value></parameter

This might get things working for you.

Rick
