JMS filtering based on selector

Hello,

Using camel 2.2, I'm attempting to select only certain messages from queue
using the following:

from("activemq:queue:somequeue?selector=clientid='someid'").to(someOtherQueue)
where 
clientid was set using: exchange.getOut().setHeader("clientid", "someid")

Is above correct? For some reason, I don't get the filtered message and the
result is camel return ALL messages of the initial queue?

Thanks.

Check the unit tests of camel-jms to see some samples.

  Hi there,

you need to pass the "=" as "%3D" as stated in the component docs.


See:
http://camel.apache.org/jms.html

So it would be:

from("activemq:queue:somequeue?selector=clientid %3D 'someid'").to(someOtherQueue)


Bye,
Norman

Hi Hossein,

Before Camel 2.3.0, we don't support the selector in CamelConsumerTemplate.

Anyway the selector option is an SQL92 predicate. Some character such as 
= should be encoded as %30 to be interpreted by Camel.

JB
