I have a stateful session bean which holds a reference to an entity
bean. When I try to call a method on the entity bean outside of a
transaction, I get "Error getting application tx data map" because of a
NullPointerException in JDBCStoreManager.getApplicationTxDataMap().
The stateful session method has transaction "Supports".
The entity bean method has transaction "Supports".
The entity bean read ahead strategy is "on-find".
Everything is using local interfaces only.
I'm using JBoss 3.0 release on Sun JDK 1.4.
** Everything works when the entity bean method is changed to "Required"
**
Anyone know what's up? I should be able to access an Option B (the
default) bean outside of a transaction and get cached (albeit stale)
data, yes? Is this a bug?
Here's my stack trace. Note that $Proxy48.getMyData() is the stateful
session bean method and $Proxy47.getData() is the entity bean.
Thanks in advance for any feedback!
