Camel-Hazelcast: Adding values into a Map

[doug5791 <to...@uwgb.edu>]

I am dealing with data in a route where the body of the exchange is a single
string. I have been able to add this string from the body of the exchange to
the Hazelcast grid, however, I would like to add the string to a Map instead
of a list. The documentation I found  here
<http://camel.apache.org/hazelcast-component.html#HazelcastComponent-map>  
does not show a clear example of how information from a "real" exchange is
added to the Map; only a template example.

Using the below route does not add the string values to the map: (probably
because there is no key?)

from("consumer:test")
.setHeader(HazelcastConstants.OPERATION,
constant(HazelcastConstants.PUT_OPERATION))
.toF("hazelcast:%shmap", HazelcastConstants.MAP_PREFIX);

Any ideas on how to provide a key for the value going into the map? Assuming
that is the issue.

Thanks ahead of time,
-Doug

On the page you mentioned is an example request that is done with a
producer template:

template.sendBodyAndHeader("direct:[put|get|update|delete|query]",
"my-foo", HazelcastConstants.OBJECT_ID, "4711");

my-foo => message body
HazelcastConstants.OBJECT_ID => message header name
4711 => message header value

So, to add the map key to your message you need to do

.setHeader(HazelcastConstants.OBJECT_ID, yourMapKey)
