[solved] activemq-camel: accessing a javax.jms StringProperty ?
indeed, that works!
I don't understand the background why the camel.Exchange class has less methods than the javax.jms.Message class, but as there is a clever "workaround" I am fine.
Thanks
Peter

Camel JMS transfers JMS properties to Camel message headers.

So check exchange.getIn().getHeader(...) in your processor.

Camel exchange needs to work with multiple components, so it doesn't make
any sense to have specific methods used only for JMS message. That's why
there is a this "translation" to headers.
