Q:

camel choice with json

I've written camel choice and input for route is xml. shown below:
I want to write choice with json as an input so how to evaluate the json to route to next component. Kindly guide me.
JSON is: 
{
  "service": { "serviceType": "OtherServcie" }
}

<choice>
 <when>
  <xpath>/service/serviceType='PaymentServcie'</xpath>
  <log message="In PaymentServcie"/>
 </when>
 <otherwise>
  <log message="In OtherServcie"/>
 </otherwise>
</choice>

A:

Maybe too late, but the answer is to use camel-jsonpath.
<route>
  <from uri="direct:start"/>
  <choice>
    <when>
      <jsonpath>$.service[?(@.serviceType=='PaymentService')]</jsonpath>
      <log message="In PaymentServcie"/>
    </when>
    <otherwise>
      <log message="In OtherServcie"/>
    </otherwise>
  </choice>

Don't forget the Maven dependency : 
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-jsonpath</artifactId>
    <version>${camel.version}</version>
</dependency>
