I'm trying to use JNDI. I followed the JNDI HOWTO on the Tomcat web site, but
I'm getting errors. This is the error message I'm getting.
javax.naming.NamingException: Cannot create resource instance

lms.core.Server is just a bean with two attributes and operators to set and
get them. Very basic.
Now for some debug info. When I start the server I get the following message.
So it's finding it.
XmlMapper: org.apache.catalina.core.StandardContext.addResourceEnvRef(
server/Image, lms.core.Server)
However I also get:
2002-09-01 20:22:14 StandardContext[/lms]: Bind naming operation failed :
javax.naming.NamingException: Name Image is already bound in this Context
What else should I look for?
Thanks,
John
