Jon,
Here is the original forum post that I found that talks about the same error
in a similar case:
http://main.jboss.org/forums/thread.jsp?forum=47&thread=11678
they talked about messing with the AutoCommit property of the oracle driver.
I'm not sure if our problems are related to this or not, as I don't know the
scope of this particular error message (although it seems sort of generic).
the bean that is having the problems has the following attributes in the
<enterprise-beans> section of its dd:
<entity>
<ejb-name>CSRequestBean</ejb-name>
...
<persistence-type>Container</persistence-type>
<prim-key-class>java.lang.String</prim-key-class>
<reentrant>False</reentrant>
<cmp-version>2.x</cmp-version>
<abstract-schema-name>CSRequest</abstract-schema-name>
...
</entity>
and the following <container-transaction> section of its dd:
<container-transaction>
<method>
<ejb-name>CSRequestBean</ejb-name>
<method-name>*</method-name>
</method>
<trans-attribute>Required</trans-attribute>
</container-transaction>
the session bean that calls this entity bean does so in the following manner:
(paraphrased for clarity, there is actually a subroutine that assigns all the
properties of the bean to the view object inside the for loop)
Collection c = csrHome.findAll();
Collection result = new Vector();
System.out.println("result size: " + c.size());
for(Iterator i = c.iterator(); i.hasNext();) {
LocalCSRequest csr = (LocalCSRequest)i.next();
CSRViewObject vo = new CSRViewObject();
vo.csRequestID = csr.getCSRequestID(); /* This line fails, see stack
trace
below ( $Proxy38.getCSRequestID ) */
...
result.add(vo);
}
return result;
so basically once i get a reference to the bean and use the local interface to
call one of the bean's get() methods, the transaction exception is thrown.
this entity bean is actually very simple, nothing more than a few abstract
accessors and the required ejb methods. I'm not doing anything fancy here.
the stack trace is:

(etc)
A few things:
1) This works fine with postgres on the same machine as jboss. I haven't
tried postgres on a remote machine.
2) I'm using a remote mssql2k DB.
3) I'm in the process of setting up a test case to try to reproduce this
problem but am currently stuck on another jboss problem (see my jboss-dev
post entitled 'deploy error in scanner thread')
4) this is also project-halting issue for me as well ;)
