The blocking timeout is just how long the
DataSource.getConnection() waits when all database connections are in use.

What does the this mean?

I don't see the relevence to database failover. 

If JBossMQ cannot get a JDBC connection
it will propogate the exception to the client. Either by:
1) Cannot send message - in this case the message was never sent and the client
knows this
2) Cannot acknowledge message - in this case the message was never received
the message is not lost because only a successful acknowledge deletes the 
message
it will be redelivered

If you are seeing something else show me the logging (READ THIS FIRST)
and describe the behaviour.

I am usually not very tolerant of posts like this that say "IT DOES NOT WORK".
What it usually means is the poster "DOES NOT KNOW HOW IT IS SUPPOSED TO WORK".
But in this case I sniff a bug report if I correctly understand your "JBoss 
doesn't come back". Although what this "JBoss" is that doesn't come back I can 
only guess?
Where did this "JBoss" go in the first place? Do you mean the MDB, the JMS 
server,
the sender, the database connection or what?
