Using apache camel xml route, how can I set a customized fileName from a JMS message?

With the java JMS API, I got from a DB an array of bytes and then I'm sending it to an ActiveMQ as a javax.jms.BytesMessage. After that with camel I want to put the file on a location,

I have this route in camel:

    <route>
        <from uri="activemq:queue.fileOuput"/>
        <convertBodyTo type="java.nio.ByteBuffer"/>
        <to uri="file://C:/output/"/>
    </route>

But my problem is that my file in c:\output\ directory, I got the file with the message id as the file name, like queue-preVerificacion-fileoutput-ID-jmachine-57401-1347652410053-0-1-1-1-1 but I want to put the name I have in the database, like MyFile.xml.

I have tried to set a message property like fileName and file:name, and also I saw in the apache document that I need to put a header "org.apache.camel.file.name", but with jms I don't know how to do it.

So my question is how can I put a customized name in the camel route?

Thanks to all.

I think "org.apache.camel.file.name" is for camel 1.x , in the 2.x version CamelFileName worked fine. But I wanted a more dynamic file name, name based on the content. This example using a processor worked well ( camel 2.18 ) 

 <route>
    <from uri="MQ:MY_Q_NAME" />
    <process ref="MyMessageProcessor"/>
    <to uri="file://E:\OUTPUT" />
</route>

    Inside the Processor :     

exchange.getIn().setHeader(Exchange.FILE_NAME, myFileName);

you just need to set the "CamelFileName" header value (based on a message header, etc)

<route>
    <from uri="activemq:queue.fileOuput"/>
    <convertBodyTo type="java.nio.ByteBuffer"/>
    <setHeader headerName="CamelFileName">
        <constant>${header.fileName}</constant>
    </setHeader>
    <to uri="file://C:/output/"/>
</route>

Just place the file name in the jms message (as a string property).

// Something like this if you send the message using plain java/jms:
msg.setStringProperty("filename","MyFile.xml");
..//Send msg

Then you can do something like this in camel

<to uri="file://C:/output/?fileName=${header.filename}"/>
