[jira] [Created] (CAMEL-4503) Recipient List cannot vary
destination by changing property in an expression
Recipient List cannot vary destination by changing property in an expression
----------------------------------------------------------------------------
Key: CAMEL-4503
URL: https://issues.apache.org/jira/browse/CAMEL-4503
Project: Camel
Issue Type: Bug
Reporter: Jonathan Anstey
This is probably due to producers being cached based on unresolved endpoint URI, rather than the resolved endpoint URI. Haven't tested this theory out though.

Unfortunately I just realized that the mentioned workaround doesn't work :(
I'm investigating why it isn't I'm down to the following right now:
answer = endpoints.get(getEndpointKey(uri));
in DefaultCamelContext does give me the wrong Endpoint, at least it's bound to the wrong URI.
but maybe this is also because it seems to be a singleton, maybe setting it to non-singleton
does work :)

it's called from

in RecipientListProcessor.createProcessorExchangePairs(...)
The following scenario doesn't work right now for the workaround, this might be a different bug though:
- Recipient A is resolved the way it should work and can be called
- if Recipient B is questioned it also works and can be used.
- if Recipient A is questioned from the cache again, Recipient B is provided and therefore the requests end up
on the wrong host.
I also added a comment to the mailing-list about this.

Willem Jiang commented on CAMEL-4503:
-------------------------------------
The NPE is caused by the clone method of CxfEndpoint, as you know CxfEndpoint extends the ServiceSupport object which has lots of AutomBoolean objects.
If the CxfEndpoint instance is started, the cloned CxfEndpoint will not start again.
It looks like calling the clone method is not a idea way to resolve such issue. I'm still looking for a good solution.

[jira] [Commented] (CAMEL-4503) Recipient List cannot vary

Claus Ibsen commented on CAMEL-4503:
------------------------------------
CAMEL-4139 causes this problem, it will lookup existing bean by its id, and reuse that as CxfEndpoint.
Even if CxfComponent is creating a new CxfEndpoint.
It seems the problem is that if you omit the address in the <cxf:cxfEndpoint> in the XML file.
And then you want to use that <cxf:cxfEndpoint> bean but specific the address at runtime. Then CxfComponent
will still hand out a shared CxfEndpoint.
It guess the tricky part is that with cxf:bean:xxx you refer to a bean, and then you *also* provide additional configurations which should override.
This seems a hard path to support. Maybe cxf:bean:xxx should be made to not accept any parameters at all, if that makes sense.
Alternative the cxf:bean:xxx should be sort of a template, and then being able to create "clones" of itself.

@Claus
That's my bad, I will update the copy method of CxfEndpoint by setting the list reference with a deep copy one.

------------------------------------
Willem I have committed an unit tests that reproduces the issue
tests/camel-itest/src/test/java/org/apache/camel/itest/greeter/RecipientListCxf2Test.java
With your recent fix on trunk (eg the clone) the problem with picking up the wrong bean is resolved as far.
But we get a NPE exception later.

The CxfBinding is null on the endpoint. So I guess a little more fix is needed. Do you mind digging into this?

Willem Jiang commented on CAMEL-4503:
-------------------------------------
In most case the configure of cxfEndpoint bean will not be changed, it should be OK if you just reuse the bean endpoint.
If there are some parameter which can be used to override the configuration in the endpoint uri, we could clone a new endpoint to use.

Okay the bug seems to be in camel-cxf, in CxfComponent.createEndpoint. As it return the same endpoint instance even though the ?address is different.
