Facing problems while using Set Header camel Processor

[sailaja p]

Hi All,

I am facing some difficulty when deploying a Camel Spring XML configuration
with Message Translator pattern and Set Header Processor into Service mix
3.4.0.1.

I have defined a route with JMS Endpoint(TestMF)-> Set Header Processor
(Xpath) -> JMS Endpoint (TestMF1) -> Message Translator (Header) -> Convert
Body To (String) -> JMS Endpoint (TestMF2).

Below is my Camel configuration file and the input xml.

Camel Configuration

<beans xmlns="http://www.springframework.org/schema/beans";
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
        xsi:schemaLocation=" http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://activemq.apache.org/camel/schema/spring
http://activemq.apache.org/camel/schema/spring/camel-spring-1.5.0.xsd";>
        <camelContext id="camelroute"
                xmlns="http://activemq.apache.org/camel/schema/spring";>
                <route xmlns="http://activemq.apache.org/camel/schema/spring";
                        id="null_1">
                        <from uri="jms:queue:TestMF" id="JMS_0" />
                        <setHeader headerName="TestHeader" id="SetHeader_0">
                                <xpath>//Input</xpath>
                        </setHeader>
                        <to uri="jms:queue:TestMF1" id="JMS_1" />
                        <transform id="MessageTranslator_0">
                                <description>A special filter to translate one 
data format into
another</description>
                                <header>TestHeader</header>
                        </transform>
                        <convertBodyTo type="java.lang.String" 
id="ConvertBodyTo_0">
                                <description>To convert using the default 
content type to a particular
type</description>
                        </convertBodyTo>
                        <to uri="jms:queue:TestMF2" id="JMS_2" />
                </route>
        </camelContext>
</beans>

Input File is 

<Sample>
<Input>Test</Input>
</Sample>

I am sending the above input xml to the JMS Endpoint (Q1). I was expecting
that the Set Header Process adds a Header to the message and it assigns
XPath Expression output as a Header value (TestHeader="Test"). But I didnt
observe the header in the message received at JMS Endpoint (Q2). But the
Message Translator is processing the message succesfully based on the header
that is set by the Set Header Processor. I have two questions regarding
this.

1. Why I didnt see the Header in the JMS Endpoint (Q2)?
2. Can I assign the node value to a header? Like assigning the following
value to the header.

<Sample>
<Input><Value>Test</Value></Input>  ------> apply Xpath, /Sample/Input  
------->  assign this "<Value>1234</Value>" to a Header
</Sample>

Thanks in advance,
sailaja.
