Intermittent NoSuchBeanException in a Camel Route Test
Hi,
I've got a pretty simple Blueprint Camel route, e.g.
<blueprint>
<Code omitted for brevity>
<camelContext id="blueprintContext"
xmlns="http://camel.apache.org/schema/blueprint">
<template id="producerTemplate" />
<route id="myRoute">
<from uri="fabric:key:queue" />
<split parallelProcessing="true">
<simple>${body.getMyRequest}</simple>
<log message="Single My Request is ${body}"/>
<to uri="direct:processMyRequest" />
</split>
</route>
</camelContext>
</blueprint>
When deployed into a Fuse ESB Fabric messages route correctly. Like a good
developer, I've written a route test (which extends
CamelBlueprintTestSupport), e.g.
public class MyRouteTest extends CamelBlueprintTestSupport {
private static final String MESSAGE = "Some message";
@Produce
protected ProducerTemplate producerTemplate;
@Test
public void messageSuccessfullyRouted() throws Exception {
getMockEndpoint(MOCK_TO_QUEUE).expectedMessageCount(1);
producerTemplate.requestBody("fabric:key:queue", MESSAGE);
assertMockEndpointsSatisfied();
}
@Override
protected String getBlueprintDescriptor() {
return "/OSGI-INF/blueprint/blueprint.xml";
}
// Code omitted for brevity
}
Now, running the test (as part of my maven build) occasionally gives me a
NoSuchBeanException:
org.apache.camel.NoSuchBeanException: Found bean: producerTemplate in
BlueprintContainer:
org.apache.aries.blueprint.container.BlueprintContainerImpl@67ae0c6e of

Anyone got any ideas?
Many thanks

Hi
I think only in a recent Camel release the camel-blueprint supports
the IoC in your unit test classes and whatnot.
So upgrading Camel may help.

Thanks for the prompt response Claus, it seems to have done the trick.
Out of interest, any thoughts on what makes it an intermittent problem? Is
it something in the way / order the bean lookup occurs?

Hi
Remove the <template> from your xml.
And the ProducerTemplate from your unit test. There is already an
template out of the box, with the name template.
See the unit tests in camel-test-blueprint for examples.
