ACS - Java Messaging Service Destination

i everybody,

I´m trying to figure out how the ACS - JMS Destination works. I'm aware on how ACS works when it creates a file (pdx or axml) in a directory. When using JMS I supposed it would convert the file into an exposed xml in the SOA server side, but what I get is a kind of binary data as pasted bellow. Is that correct, I mean, to use this data I´d need to convert it?
