hi,
in a
previous post with subject "[JBoss-user] "can't enlist" error on second pass
through resource adapter" i described a problem i was having with multiple,
non-concurrent invocations of a resource adapter via a stateless session
bean. the responder's suggestion (swapping the order of
UserTransaction.begin() and ConnectionFactory.getConnection()) got me past this
problem. i still have an outstanding question out as to why this should be
required, but we'll leave that as a separate thread.
my new
problem is that i can't perform multiple, concurrent invocations of the resource
adapter. during the 2nd call to ConnectionFactory.getConnection(), i get
the "Can't enlist - already a tx!" error. in case it's helpful, this is
the same error i got before i flipped the order of UserTransaction.begin() and
ConnectionFactory.getConnection().
i put some
comments in the EJB method that invokes the resource adapter to help me track
down what state caused the problem. i also threw in a sleep call to assist
as well.
same
environment as in my previous post, which i'll repeat here:
i'm using
jboss 3.0.4 with tomcat 4.1.12. my jdk is 1.3.1.06. platform is w2kp
sp3. the resource adapter supports XA. res-sharing-scope is set to
Unshareable in the ejb-jar.xml file of the EJB that uses the resource
adapter.
this use
case works fine under oc4j 9.0.3 and TeS 7.3.
any
assistance would be appreciated. i'm trying to understand the
feasibility/cost of a port of our resource adapter to jboss - an inability to
use the resource adapter in a concurrent fashion would likely prevent us from
using jboss.
thanks.
