select message via camel filter

[Wang Yan]

I used below example to select message.
although it can send matched message to toqueue
but not matched messages are also dequeued
What I want to achieve is only matched messages will be
selected and sent to toqueue .

Any suggestion or hints how to do this with camel filter?

from("activemq:queue:inputqueue?transacted=true")
.filter(header("foo").isEqualTo("bar"))
.to("activemq:queue:toqueue");
