I have Tomcat 5.5.7 installed.
Firebird SS 1.5.2
Jaybird 1.5.5
Windows XP Professional SP 2

I read these two pages
http://jaybirdwiki.firebirdsql.org/config/TomcatConnectionPooling
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jndi-datasource-examples-howto.html

I added firebirdsql-full.jar to the webapp's lib directory.

I get this error

javax.servlet.jsp.JspException: Unable to get connection, DataSource
invalid: "org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create
JDBC driver of class '' for connect URL 'null'"

The same error if I copy the firebirdsql-full.jar to the
tomcat/common/lib directory.

Here's how I access the pool

<sql:query var="rs" dataSource="jdbc/TestDB">
select id, nombre, telefono from persona
</sql:query>

<h2>Results</h2>

<c:forEach var="row" items="${rs.rows}">
Id ${row.id}<br/>
Nombre ${row.nombre}<br/>
Tel: ${row.telefono}<br/>
</c:forEach>


Thanks for any help.
