Apache Camel: How to rebuild the url based on the old one or the header -

i using route on camel starts server used access point request, re-directions, gateway database, etc. , want redirect request service in server , compose url based on request. have made processor gets header , puts in new url. new url not executed...

here code:

camelcontext context = new defaultcamelcontext();  connectionfactory connectionfactory =     new activemqconnectionfactory("vm://localhost?create=false"); context.addcomponent("activemq", jmscomponent.jmscomponentautoacknowledge(connectionfactory)); context.start();  processor redir = new redirectprocess(); from("jetty:http://localhost:8080/middleware")        .choice()     .when(header("redir")).process(redir)     .end() 

and processor

public class redirectprocess implements processor {     string value = null;     string head;      public void process(exchange inexchange) throws exception {         head = inexchange.getin().getheader("redir").tostring();         camelcontext camelcontext = new defaultcamelcontext();         camelcontext.addroutes(route());         camelcontext.start();         producertemplate template = camelcontext.createproducertemplate();         template.sendbody("direct:start", "hello camel");         system.out.println(head);     }      public routebuilder route() {         return new routebuilder() {             public void configure() {                 // can configure route rule java dsl here                 system.out.println("passed here!");                 from("direct:start")                     .to("http://localhost:8081/functlayer/tool/start/tool/" + head + "");             }         };     } } 

it not work this. don't try create contexts nor routes in runtime. use recipient list pattern (http://camel.apache.org/recipient-list.html).

your code like:

    camelcontext context = new defaultcamelcontext();      connectionfactory connectionfactory = new activemqconnectionfactory("vm://localhost?create=false");                     context.addcomponent("activemq",jmscomponent.jmscomponentautoacknowledge(connectionfactory));      context.start(); from("jetty:http://localhost:8080/middleware")        .choice()         .when(header("redir"))             .recipientlist(simple("http://localhost:8081/functlayer/tool/start/tool/${header.redir}"))         .end()
