If the name of the global resource in server.xml is defined as
<GlobalNamingResources>
<Resource [attribs] name="jdbc/MYDATASOURCE"/>
<ResourceParams name="jdbc/MYDATASOURCE">
<param>...</param>
</ResourceParams>
</GlobalNamingResources>
then the resourcelink in context.xml is
<Context [attribs]>
<ResourceLink
global="jdbc/MYDATASOURCE"
name="jdbc/MYDATASOURCE"
type="javax.sql.DataSource"/>
</Context>
(not sure if listing the exact datasource specification would be a
security breach, so I'm munging the actual datasource name, but
everything else is the same, including upper/lower case)
