I have successfully configured a JNP server using and was able to add objects
to the context. In one example, I added a Commons DBCP connection pool class
into the context. I was able to take the same JVM and retrieve this reference
and use it successfully. However, when I access the DataSource object using
another JVM instance, the connection pool returns null on the
ds.getConnection() method. The code successfully gives me a reference to the
DataSource object (that is not null), but for some reason the "pool" reference
in the DataSource object is null. Below is the client code used to retrieve
the object. Please let me know if you need more information. All other
"basic" type objects such as String and Integer are successfully read. I am
only having the problem with the DataSource object.
Thank you for taking time to read my post.
