Example of using BlobMessage

[Norman Maurer <no...@apache.org>]

Hi all,

we just switched to using Camel + Activemq for message routing and
spooling in JAMES. At the moment we store the whole MimeMessage as a
byte array in the payload of the Exchange. This is super inefficient
because of the possibility of very big emails. So I consider using
BlobMessages for storing the MimeMessage out of the band. So is there
any example in sending a BlobMessage via ProducerTemplate ?


Thx,
Norman

Hi Claus,

after having more thoughts about the claim check thing, I don't think
its the right thing for my need. I need to be able to lazy load some
stuff on demand. I don'T know when I need it because users can plugin
their own implementation to process the object. Sometimes they don't
need to access the MimeMessage so I don'T want to load it. Sometimes
they do.


So I need more something like lazy loading in the JPA world.. So I
will look into the BlobMessage.

Thx again,
Norman

Hi Claus,

yeah claim check sounds like the one I was looking for.

Yes I was refering the the AMQ BlobMessage because from my
understanding it is the way you usual handle such stuff with AMQ.

Thx again,
Norman

By out of band I assume you mean the claim check EIP?
http://camel.apache.org/claim-check.html

And BlobMessage is it the AMQ type?
org.apache.activemq.BlobMessage

I recon you need to grab the InputStream from the BlobMessage to be
used as the body to be send using ProducerTemplate.
