Not able to update Camel exchange property

Question

I am setting a property of camel exchange in route 1. I am trying to update the same in the second route inside a splitter. but in the second iteration of splitter i am getting the original value that I set in the route 1 instead of the new updated value. Below is the sample i am trying..

<route handleFault="true" streamCache="true" id="route1">
<from uri="cxfrs://bean://test?synchronous=true"/>
        <bean ref="testBean" method="setMyProperty"/>// setting initial value for property
        <to uri="direct:directCall"/>
</route>

<route handleFault="true" streamCache="true" id="route2">
    <from uri="direct:directcall"/>
    <log message="Inside Second call..."/>
    <split>
     <jsonpath>some Json path</jsonpath>
      <bean ref="formatConvertor" method ="convertLHMToJSON(${body})"/>

    <split>
      <jsonpath>some json path</jsonpath>
    <bean ref="PropertySetter" method ="setProperty"/> //I am setting new value in this method
     </split>
   </split> 

Inside the beans:

   public void setMyProperty(Exchange exchange) {
            exchange.setProperty("testProp", "hello");
        }

    public void setProperty(Exchange exchange) {
           sysout(exchange.getProperty("testProp").toString())//this always prints "hello"
           String x=exchange.getProperty("testProp")+some other value;// in all iterations of split I am getting 'hello' as the value of the property instead of new value
            exchange.setProperty("testProp", x);
            sysout(exchange.getProperty("testProp").toString())// this line prints the new value
        }

Why the property is not updated? Even i tried setting in headers. same result. Thank you.

Answer 1

You must use a split-aggregate pattern and copy the property value during each iteration of the split from the old exchange to the new exchange because every time when the split iteration happens a new exchange is created from the source message (only carrying the properties & headers set before the split) recover headers value after split apache camel
