Reprocessing poison messages

Question

Hi all,
We are using weblogic v923. We are using Spring JMS API (MDP, context files) to listen and process the JMS messages from the Weblogic cluster's distributed error queues.
In some cases we observe bad formatted data which needs manual correction. Such messages, we are treating them as poison messages by setting a boolean and a string property on the JMS message and put them back on the error queue and use the message selector on the spring defaultmessagelistnercontainer to filter out those messages so that they are not reprocessed.
Now, how to fix the poison message and reprocess it? Is it possible to correct the message content and revert the boolean and string properties that were originally set to mark it as a poison message?
Is there a way that weblogic allows to edit the message in the admin console? If not, what are the best ways to accomplish this?
Thanks in advance for your valuable input.

There's no way to edit a message while it sits in a queue.
It would be possible to use WLST scripting, java mbeans, or the console to export the message to a file, delete the original problem message, and then import the message back into the main queue -- but I think this is complex and error prone.
Ideally, I recommend modifying your error processing MDP to forward messages that require administrator intervention to a new queue, and then writing a simple application that your admins can use to (A) dequeue the problem message from the new queue, (B) edit the message, and (C) inject the edited message back into the system.
