We had the same problem when jndi.properties wasn't on the classpath... Once
we have fixed it, it went away.

It seems that it is possible to get the UserTransaction object
in a servlet via Tomcat.
In the security sample that you can find in the Jonas release
there is the code of the servlet :
$JONAS_ROOT/examples/src/security/ejbSample/WEB-INF/classes/ServletOP.java
in which we do
UserTransaction utx = null;
try {
utx = (UserTransaction)
PortableRemoteObject.narrow(initialContext.lookup("javax.transaction.UserTra
nsaction"),
UserTransaction.class);
} catch (Exception e) {
when we follow instruction that you will find in the
$JONAS_ROOT/examples/src/security/README
we have no problem to run this example that use Tomcat & JOnAS.
Best regards,
