Pessoal.
Estou usando TomCat 5.5, jdk 1.5 e MySQL 5 e estou com um problema na hora de obter a conexão:
[code]SEVERE: >>org.zkoss.zk.ui.UiException: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class ‘’ for connect URL ‘null’

No meu server.xml tenho a seguinte configuração:
<?xml version="1.0" encoding="UTF-8"?>

</Service>
</Server>
Estou usando o driver: mysql-connector-java-5.0.4-bin.jar
Já adicionei no commom/lib do tom cat.
No meu web.xml coloquei a tag resource-ref:
<resource-ref>
<res-ref-name>jdbc/adcDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth> Container</res-auth>
</resource-ref>
Alguem poderia me ajudar?
