Hi claus, I tried implementing your logic and it is as follow: public class MyCustomLoadBalancer extends SimpleLoadBalancerSupport
{ public void process(Exchange exchange) throws Exception { Processor target = chooseProcessor(exchange); XPathBuilder sessionID = XPathBuilder.xpath("substring(string(/*[local-name()='Envelope']/*[local-name()='Header']/*[local-name()='ReplyTo']/*[local-name()='ReferenceParameters']/*[local-name()='ServiceGroupId']/text()), 10)", String.class); String session = sessionID.evaluate(exchange, String.class); HashMap hm = new HashMap(); hm.put(getProcessors(),session); target.process(exchange); } protected Processor chooseProcessor (Exchange exchange) throws Exception { Namespaces env = new Namespaces("soapenv", "http://schemas.xmlsoap.org/soap/envelope/"); env.add("wsa", "http://www.w3.org/2005/08/addressing"); env.add("axis2", "http://ws.apache.org/namespaces/axis2"); Object expression = exchange.getIn().getHeader("test", env.xpath("substring(string(/soapenv:Envelope/soapenv:Header/wsa:ReplyTo/wsa:ReferenceParameters/axis2:Serv‌ iceGroupId/text()), 10)", String.class)); if (expression.equals() } } Now the problem is how can I call the hashmap object in my choose procesor method? I cannot extend my choose processor method. I am struck in the if part of the choose processor. Could you please assist me in this? -- View this message in context: http://camel.465427.n5.nabble.com/Using-a-custom-based-load-balancer-tp5719841p5719857.html Sent from the Camel - Users mailing list archive at Nabble.com.
