Subject RE: Please try out the upgrade jar
Date Mon, 05 Jun 2006 18:37:06 GMT
Hi David,

The dependency tags for the the module ID of the server wide datasource in
the Geronimo-web.xml were not required for 1.0, so it is unnatural for user
to know they are required for 1.1.  If the upgrader tool doesn’t indicate
that, user will just have to go figure that out by luck.

One a second thought, I don’t quite understand why we need to have the
datasource as the dependency in 1.1 while we don’t need it as the dependency
in 1.0.  The Geronimo-web.xml already has the ref-name and resource-link
information within the resource-ref tags.

Thanks, Lin

datasource dependency, which will cause failure of application deployment..

Do you think the upgrade tool should insert comments into every plan about
likely problems such as this one about datasources?  Since it's possible to
resolve a resource-ref without a plan entry if the resource-ref uses the
same name as the datasource plan, we'd have to look at the j2ee deployment
descriptors to be sure whether or not a jndi ref was present.   Looking into
dds is beyond what I think the upgrade tool should be doing.  However,
adding comments always would be pretty easy to do, I didn't think to do it
however.

thanks

How old is the upgrade.jar you are using?
Noticed that your generated plan still has the old
context-priority-classloader element in it.....
