Display contents of Oracle AQ SYS.AQ$_JMS_TEXT_MESSAGE

Question

I have an application that uses JMS op top of Oracle advanced queuing. I would like to do a query on the queue table that shows the content of the message (which in my case is XML). So when I do a 'select user_data from [queue_table]' I get 'AQ SYS.AQ$_JMS_TEXT_MESSAGE' as a response.

Is there a function so that the contents of this message can be shown? Something like 'select FUNCTION(user_data) from [queue_table]' or something?

I googled, scanned numerous Oracle articles about queuing, but I cannot find this thing. I suspect there is a simple way to do this, but I cannot find it.

I struggled with this one as well. I've written an answer here: http://rwijk.blogspot.com/2009/02/whats-in-my-jms-queue.html .

Answer 2

So I suppose it should be:

select queue.user_data.text_vc from [queue_table] queue
