(i posted the following to the user list without a
response. it was suggested to me by someone with jboss to post to the dev
list)
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. res-sharing-scope of Shareable
causes other problems that i'm currently trying to debug. i've found
minimal documentation on res-sharing-scope - perhaps the Unshareable setting is
the problem?
this
use case works fine under oc4j 9.0.3 and TeS 7.3,
albeit without res-sharing-scope set.
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.
