The famous Cant find the request Observer
Hi,
I have spent 2 days on this so any ideas on how to debug this further would
be appreciated.
I'm using JDK 1.7, Spring 3.2, and CXF 2.7.3. With Spring I'm using the
Java config (not xml).
I keep getting the error
WARNING: Can't find the the request for
http://localhost:8080/rest/api/people's Observer
I think the error is related to some interaction between Tomcat and the
CXFServlet. I had this working for a couple of weeks, so I suspect it has
something to do with the order of the classpath and not the configuration.
I found this project which I can use to reproduce the problem. It works
correctly with the embedded Jetty server, but NOT with Tomcat.
git clone -b tomcat-embedded https://github.com/reta/spring-one-jar.git
mvn package
java -jar target/spring-one-jar-0.0.1-SNAPSHOT.one-jar.jar
This fails with:
curl http://localhost:8080/rest/api/people?page=2
But the same procedure with Jetty works.
git clone -b jetty-embedded https://github.com/reta/spring-one-jar.git
With Tomcat the application path (@ApplicationPath) is correctly printed,
so I think it must be related to the CXFServlet and the url-pattern.
"INFO: Setting the server's publish address to be /api"
@Bean
public Server jaxRsServer() {
JAXRSServerFactoryBean factory =
RuntimeDelegate.getInstance().createEndpoint( jaxRsApiApplication(),
JAXRSServerFactoryBean.class );
factory.setServiceBeans( Arrays.< Object >asList(
peopleRestService() ) );
factory.setAddress( "/" + factory.getAddress() );
factory.setProviders( Arrays.< Object >asList(
jsonProvider() ) );
return factory.create();
}
Thanks,
Al

Hi Daniel,
Yes, that gets me closer. The failure is completely random
(and reproducible as random). The problem seems to be the order of the bus.
If "cxf" is last in the list it fails.
INFO: Pre-instantiating singletons in
org.springframework.beans.factory.support.DefaultListableBeanFactory@d88c8f:
defining beans
[org.springframework.context.annotation.internalConfigurationAnnotationProcessor,org.springframework.context.annotation.internalAutowiredAnnotationProcessor,org.springframework.context.annotation.internalRequiredAnnotationProcessor,org.springframework.context.annotation.internalCommonAnnotationProcessor,appConfig,org.springframework.context.annotation.ConfigurationClassPostProcessor.importAwareProcessor,jaxRsServer,jaxRsApiApplication,peopleRestService,peopleService,jsonProvider,cxf];
root of factory hierarchy
But it works when the order is different:
INFO: Pre-instantiating singletons in
org.springframework.beans.factory.support.DefaultListableBeanFactory@1a309d1:
defining beans
[org.springframework.context.annotation.internalConfigurationAnnotationProcessor,org.springframework.context.annotation.internalAutowiredAnnotationProcessor,org.springframework.context.annotation.internalRequiredAnnotationProcessor,org.springframework.context.annotation.internalCommonAnnotationProcessor,appConfig,org.springframework.context.annotation.ConfigurationClassPostProcessor.importAwareProcessor,cxf,jaxRsServer,jaxRsApiApplication,peopleRestService,peopleService,jsonProvider];
root of factory hierarchy
I will try your fix tomorrow...but thanks for getting me pointed in the
right direction. I assume this fails in part due to the voodoo from the
Spring classloader. I don't know enough to know how I can influence the
order of this.
Cheers,
Al

Try this:

I think you are getting a different bus in the factory depending on whether the cxf() method is called first or the jaxRsServer() method is called first.

This is strange..
Compiled with 1.6.0_29, works.
Compiled with 1.6.0_29, run with 1.7.0_17, works.
Compiled and run with 1.7.0_17, fails.
Logs are on:
http://pastebin.com/qj1asZpq
Same results with CXF 2.7.4, 2.7.3, 2.6.7
I suspect some classpath/class loading issue. I'm not sure how to debug
that.

And I cannot reproduce it at all if I update to CXF 2.7.4. Please update and try again.

What's interesting is that it works fine for me with Tomcat when using Java6, but not with Java7. Not sure what that means yet.
