Hi,

I use mule 2.2.1 running on host1 & activemq 5.2 running on host2. My mule
conf is below.

Scenario : File -> JMS -> FTP

All works fine, except when i put a big file (~14 MB) i got errors
indicating "java out of memory".

Mule log:

JMS must read full file contents in memory, there's no streaming in specification. Increase java heap size for your run.

Hi Andrew,

Thanks for your response.
I use jms in order to apply xa-transaction between file and ftp
Increase java heap size, Do you think is a good approach ?

If you're using JMS purely for the transactionality, why not use VM instead?
