Tomcat 5 - Exception invoking method addResourceLink

[Christian]

Hi! I'm having a problem adding a second resource link to my web app,
the first one works fine. I'm using Tomcat 5 and db2/400 db. Tomcat
gives the following exception:

2003-nov-17 12:29:39 org.apache.commons.modeler.BaseModelMBean invoke
ALLVARLIG: Exception invoking method addResourceLink

The second resource link is identic to the first, except from the JNDI
name offcource.

My server.xml:

type="javax.sql.DataSource"/>
<Resource name="jdbc/SFDS4" scope="Shareable"

Adding a resource link to the datasource SFDS7 works fine but when i
try to create a link to SFDS4 the above error occurs.
