How do I filter out unwanted header properties propergated in route
Apache Camel has been a revelation in componentising flow based applications.
Although getting started has been a hair pulling exercise at times..but
definitely rewarding. I have the following route defined
from("imap:mailhost").process(new
AttachmentProcessor).to("bean:translate").to("jms:queue:output")
When I inspect the JMS header of published message, it contains unwanted
properties propergated by camel from original email along with processing
involved in the route. Example
Properties={ to={String:user1@abc.com, user2@abc.com}
org_apache_camel_splitSize={Integer:43} precedence={String:list}
subject={String:Subject line from email}
org_apache_camel_MultiParameterArray={String:false}
from={String:user1@abc.com} org_apache_camel_splitCounter={Integer:12}
How do I prevent these internal headers being copied into JMS header?

If you need to remove a single header then there is a removeHeader DSL node.
However since there are many you can use a processor or bean to do a
bit of java code
eg to remove them all
exchange.getIn().setHeaders(null);
You can also set a new HeaderFilterStrategy on your JMS endpoint that
can do the filtering.
