Hello Robert,
In the current J2EE specification, support for transaction management from
application clients is not required.
(from section 4.2.3:
"The J2EE Product Provider is not required to provide any transaction
management support for application clients.")
The spec only requires that java:comp/UserTransaction is made available to JSPs
and Servlets.
However, nothing says we can't support this so since you have expressed an
interest in it we will support it, however, if you use it, if might not work
with other J2EE servers.
Also, your way of getting the InitialContext is not recommended since your code
will contain references to Orion classes. Instead, put your properties in a
jndi.properties file.
Regards,
Karl Avedal
