Subject Re: QueueBrowser does not return large messages
Date Fri, 21 Sep 2012 13:37:39 GMT
Thanks for your response. I am wondering that nobody ran in such an issue
so far. No, there is no truncation - neither in the web console nor in my
own implementation.

So your suggestions is to browse/view the messages via JMX using an
appropriate destination policy? is this already possible now or does this
need some code changes anyway?

In JConsole, when doing a browse() all messages are returned. Some of them
(I guess the smaller ones) contain a bodyPreview field (with a byte[255]
since I am transferring byte[]) and some messages do not contain the
bodyPreview field.


Best regards,
Andr
