Hi, Looks like you might be importing the wrong class there. AQ
is the messaging provider in the Oracle Database.
You want to make sure you are using the normal Java JMS classes.
I would go back and check you have the rightJAR files in your
classpath for your application, and if you are using an IDE, make
sure it did not import the wrong
classes.
