Subject RE: How to put "properties" on a message so they are accessible later
Date Tue, 12 Sep 2017 20:45:17 GMT
Right now I'm using Artemis 2.2.0. 
I've done a bit more research and experimentation. It seems that I can set a header in Camel,
send the message to a queue/topic hosted on Artemis and read the header as a "stringProperty".
The header keys also show up when I do a "getProperties" call. However, if I try to overwrite
that field in my ActiveMQServerPlugin (specifically the beforeSend call), the change is not
propagated to Camel. IE, if I send a message with the header "testHeader" with a value of
"testValue", I can see, in Artemis, "testHeader" as a property on the message with the value
of "testValue". If I then try to overwrite that value with "newValue", when I access the message
and its headers in the consumer, the header is still "testHeader" with the value of "testValue",
whereas I expect it to be "testHeader" with a value of "newValue".

To be clear, you're asking about doing this in Artemis, not ActiveMQ 5.x, right? What version
of Artemis?
