Hello
Web applications gain access to Globally Named JDBC Resources  
<GlobalNamingResources> by adding a <ResourceLink> to context.xml

Then using code like:

Context initContext = new InitialContext();
dbLookupStr = "java:comp/env/" + dbResourceName;
ds = (DataSource)initContext.lookup(dbLookupStr);

HOW CAN code in a custom Realm gain access to one of those same Globally named 
database connection pools ?

#######

Extra info included here for background: I have a custom realm that I created 
by extending JDBCRealm it does its own authentication and uses JDBCRealm's 
getRoles() to do the authorization. Although it works much of the time, the 
inherited getRoles method causes problems. I've decided to re-write my realm 
without extending JDBCRealm,  thus I need to write my own JDBC authorization 
code, hence the above question.

Thanks in advance
Vince
