cannot load jdbc driver class 'null'

[Ralf Poppen]

We are using the tomcat 4.1.24 and the j2sdk1.4.2_02. The jdbc- driver
we use is 'mysql-connector-java-3.0.8-stable-bin.jar'
As database we use mysql Version 3.23.58-nt.
When we call the web-service we get the message "cannot load jdbc driver
class 'null'" . Who can help?

Here is an extract of the Server.xml we use

<Context className="org.apache.catalina.core.StandardContext"
cachingAllowed="true"
charsetMapperClass="org.apache.catalina.util.CharsetMapper"
cookies="true" crossContext="false" debug="0" displayName="Apache-Axis"
docBase="\axis"
mapperClass="org.apache.catalina.core.StandardContextMapper"
path="/sf/1_00" privileged="false" reloadable="false"
swallowOutput="false" useNaming="true"
wrapperClass="org.apache.catalina.core.StandardWrapper">
<Logger className="org.apache.catalina.logger.FileLogger" debug="3"
directory="logs" prefix="sf_logger." suffix=".txt" timestamp="true"
verbosity="1"/>
<Resource auth="Container" description="Resource reference to a factory
for java.sql.Connection instances that my be used for talking to a
particular database that is configured in the server.xml file."
name="jdbc/testDB" scope="Shareable" type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/testDB">

</parameter>
<parameter>
<name>logAbandoned</name>
<value>true</value>
</parameter>
</ResourceParams>
</Context>


here is the extract of the web.xml we use

<resource-ref>
<description>...</description>
<res-ref-name>jdbc/testDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>


Any help would be great.

Thanks Ralf
