Subject Re: Difficulty connecting to DB2 for iSeries from Tomcat 5.0.28
Date Tue, 21 Dec 2004 17:26:34 GMT
No matter what i do, the JNDI lookup is returning null.  What causes a
JNDI lookup to return null when the resource is defined in the
<GlobalNamingResources> section of server.xml?  Should I put the
resources into <NamingResources> in my context.xml?
