How to use same CamelContext in multiple jar on the same war

Question

I'm using the camel 2.16.2 and I need to use the one CamelContext across multiple jars as I need to have all the Camel Routers in to one CamelContext. So my war will have all those jars as maven artifacts.

Please let me know how do I handle above scenario?

Edit

Just to elaborate more on above question. In my war myApp.war, I have initialized the CamelContext. There are three jars myApp1.jar, myApp2.jar and myApp3.jar. Each jar has it own routers defined separately.

1. How do I start the routers in each jar ?
2. Can I use the same CamelContext injected to each routers?
3. If I cannot handle through jars, is it possible to implement with multiple war (myApp1.war, myApp2.war and myApp3.war) and each war having different camelContext and communicate to those routers from the main war (myApp.war) ?

Answer 1

As other guys said, you can't use the same CamelContext across different Jars. Could you explain a little what you want to do?

IMHO what you want to do is use routes defined in different Jars. So for that you can define a Camel Context and add all the routes from different Jars. Of course your Camel-Context-JAR has to have access to all those jars.

 <camel:camelContext id="camel5">
  <camel:package>org.apache.camel.spring.example</camel:package>
</camel:camelContext>

Or class by class

  <camelContext id="camel5" xmlns="http://camel.apache.org/schema/spring">
    <routeBuilder ref="myBuilder" />    
  </camelContext>

  <bean id="myBuilder" class="org.apache.camel.spring.example.test1.MyRouteBuilder"/>

Or if you are using CDI you can follow this great article https://dzone.com/articles/using-camel-routes-in-java-ee-components

After doing some research found a way to implement this. Infact we can use the same CamelContext across different jars as all jars are in the same war (Web Container).

We can implement easily with Apache Camel 2.16.2 with camel CDI. If you're using wildfly to deploy your war then you may need to add the camel patch. Download the the wildfly 9.0.2 pach

Steps are Given Below.

In your war create a servlet or restService and Inject the camelContext.

@Inject
@ContextName("cdi-context")
private CamelContext camelctx;

Create a router in the jar with below annotation.

@Startup
@ApplicationScoped
public class MyJRouteBuilder extends RouteBuilder {

In Configure method add

@Override
public void configure() throws Exception {
    from("direct:startTwo").routeId("MyJRouteBuilder")
    .bean(new SomeBeanThree());
}

Create a BootStrap Class in your jar and add the Router

@Singleton
@Startup
public class BootStrap {

private CamelContext camelctx;

@PostConstruct
public void init() throws Exception {   
    camelctx.addRoutes(new MyJRouteBuilder());
}

Add your jar as a artifact in the war pom.xml. Once you deploy the war you can see MyJRouteBuilder is Registred in the cdi-context CamelContext. So now you can access your Router anywhere you want.

Hope this would useful anyone who has the same issue what I had.
