Hi Antonin
I tried your suggestion for problem 2, but couldn't get it to work.
I've put an example that illustrates both problems here:
https://github.com/tdudgeon/camel-cdi-servlet-example
To reproduce the first problem just remove the @ContextName annotation
from the HelloRoute class.
To reproduce the second one uncomment line 25 from the same class.

I've found a couple of things I don't understand when using the camel-cdi
component.
1. The @ContextName("customname") annotation can be used to specify a custom
name for the camel context. But I'm finding that this annotation is essential.
e.g. if my app comprise just of a couple of classes extending RoutBuilder then
I MUST have this annotation present.
I would have assumed that if I only have a single CamelContext then this would
have been unnecessary?
This should work as you assume. For example, if you execute the following test:
@RunWith(Arquillian.class)
public class CdiTest {
@Deployment
public static Archive<?> deployment() {
return ShrinkWrap.create(JavaArchive.class)
// Camel CDI
.addPackage(CdiCamelExtension.class.getPackage())
// Bean archive deployment descriptor
.addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
}
static class FirstRoute extends RouteBuilder {
@Override
public void configure() {
from("direct:first").to("mock:first");
}
}
static class SecondRoute extends RouteBuilder {
@Override
public void configure() {
from("direct:second").to("mock:second");
}
}
@Test
public void test() {
}
}
You see that the two route builders get added to the default Camel context:

Could you please send more details about your deployment so that I can help
identify why that is not working as expected?
2. I'm try to use a custom thread pool. As described in the docs I use a
@Producer to generate the thread pool profile:
public class CamelContextFactory {
@Produces
@ApplicationScoped
CamelContext customize() {
DefaultCamelContext context = new DefaultCamelContext();
context.setName("mycontext");
ThreadPoolProfile profile = new
ThreadPoolProfileBuilder("poolName").poolSize(4).maxPoolSize(50).build();
context.getExecutorServiceManager().registerThreadPoolProfile(profile);
return context;
}
}
This seems to be executed as expected, but when I try to use the thread pool in
a route like this:
from("direct:foo" )
.threads().executorServiceRef("poolName")
.log("route executed");
then the pool can't be found:
Caused by: java.lang.IllegalArgumentException: ExecutorServiceRef poolName not
found in registry or as a thread pool profile.
The lookup is done by name so you need to have a @Named("poolName") bean
deployed or have the ExecutorService register manually into the Camel context (which you
do but for some reasons it does not get found).
So in your example, I would try:
@Produces
@Named("poolName")
ThreadPoolProfile profile() {
return
ThreadPoolProfileBuilder("poolName").poolSize(4).maxPoolSize(50).build();
}
And without using a custom Camel context.
Thanks for any advice on these.
Tim
Let me know if that helps.
