I'm in the process of moving an application that is in production today
on a TC 4.1.30 deployment over to 5.5.
So far, everything has moved without too much trouble. That is, until I
get to the use of commons-dbcp in the code. The code uses
BasicDataSource to interface to commons-dbcp.
Under 4.1.30 (and I believe 5.0 as well...) I can do:
Context ctx = new InitialContext();
BasicDataSource ds = (BasicDataSource)ctx.lookup("jndi string");
And I would get a data source. Under 5.5.7 and 5.5.9, ctx.lookup()
throws an Exception. BUT, neither getMessage() nor getCause() return
anything legit (both return NULL).
My setup requires me to run TC with -security. Using -verbose:class and
-Djava.security.debug=access,failure (THANKS Jon Wingfield!), I've
determined that TC 5.5.7 and 5.5.9 are loading everything and that I
have permission to access the various modules
[Opened /usr/java/Tomcat/common/endorsed/commons-dbcp-1.2.1.jar]

[Loaded org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory]
But I don't get anything legit out of ctx.lookup() :(
I'd like to see if I can debug this to isolate *where* things are going
a-stray... Can anyone set my on the correct path? A search of this
list hasn't revealed anything *other* than my JNDI string is incorrect
(I can deploy the same WAR to 4.1.30 and 5.0 and it works - so I suspect
my environment and possibly TC 5.5 and the -security setting...)
Thanks in advance!
Bob
