Subject Objectmessage max size, how can i change it?
Date Tue, 23 Dec 2008 10:13:38 GMT

Hi,

what is the maximum size of a objectmessage for sending over a
ssl-protocoll? Is it 20 MB?
Can I modify the size?

I have tested (ApacheMQ Version 5.2) with a File (~ 25 MB) and get the
following Error:

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

I have increase the MemryUsage of the SystemUsage:
<memoryUsage limit="70 mb"/>
but it has no positive effect.

Must I use a BlobMessage instead?
