I'm using OpenJMS 0.7.7 beta with Hermes 1.12.

I tried to send a text message using the default topic "topic1" that came with the OpenJMS installation and got the following message:
javax.jms.JMSException: No Delivery Mode set

I've attached the exception trace from the log file:

It seems that createTextMessage() in OpenJMS returns a TextMessage without a null DeliveryMode and the getter method is throwing the exception.

Is there a way to set the delivery mode in Hermes when sending a text message?
