No bean named 'cxf' is defined

Question

I am trying to setup a simple restful web application, using tomcat 6.0.32, cxf 2.4.1. Anytime I issue any call, I get back an exception "No bean named 'cxf' is defined", where cxf is my bus.

Looking at the application log, I can see the cxf instance is created, and cached.

But when a request comes in, it always fails saying it can't find the bean.

The only thing I can think of is that the bean is inserted in one context, and is being retrieved from another, but can't validate this or find a way around it. Any help would be greatly appreciated.

Answer 1

From your error log, I assume you use Spring, if so, you will need to add following lines to your Spring Context XML:

<import resource="classpath:META-INF/cxf/cxf.xml"/>
<import resource="classpath:META-INF/cxf/cxf-extension-xml.xml"/>
<import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>

Hope this helps.

Answer 2

If someone needs the Spring Java Based Configuration for solving this problem, there are two options:

You can import the cxf.xml file into your Java Config class with:

@ImportResource({ "classpath:META-INF/cxf/cxf.xml" })

Or you can define the bean programatically in your Java Configuration class with:

@Bean
public SpringBus cxf() {        
    return new SpringBus();
}

CXF + Spring Java Configuration class example.
