SIB And JMS

Hello All,

I am not sure how much this post suit into this forum, but posting it since it is concerned with JMS.

In earlier versions of WAS we made use of Websphere MQ to store messages, which could also be stored in Database. I know in WAS 6 we usually save it has datastore, does this mean all messages are available in database only or is it that messages are available in JMS as well as Database?
If available in JMS as well, pelase let me know where exactly can i find these messages?

In addition to that i would also want to know how can i manually add poison messages to JMS or SIB in WAS 6?

Thanks to all in advance.
