问题:

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.

回答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.

回答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.

In case anybody else gets here and is using mulesoft esb. The problem is also present in this system. To fix the issue, add the following section before the definition of the flows.

<spring:beans>
    <spring:import resource="classpath:META-INF/cxf/cxf.xml" />
    <spring:import resource="classpath:META-INF/cxf/cxf-extension-xml.xml" />
    <spring:import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
    <spring:bean class="org.apache.cxf.bus.spring.Jsr250BeanPostProcessor" /> 
    <spring:bean id="classname" name="classname" class="some.implemented.interface.path" />
</spring:beans>

回答4:

Add these dependencies in the pom file:

<dependency>
   <groupId>org.apache.cxf</groupId>
   <artifactId>cxf-rt-rs-extension-search</artifactId>
   <version>2.6.0</version>
</dependency>
<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-rs-extension-providers</artifactId>
    <version>3.0.1</version>
</dependency>

回答5:

Please check these steps in below:

1) lines mentioned in below should be included in your Spring Context XML:

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

2) Web.xml should be configured as below:

<context-param>
     <param-name>contextConfigLocation</param-name>
     <param-value>classpath*:cxf.xml</param-value>
</context-param>

3) Dependencies in below should be added inside your pom.xml:

<dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-frontend-jaxrs</artifactId>
        <version>${cxf.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-frontend-jaxws</artifactId>
        <version>${cxf.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-ws-security</artifactId>
        <version>${cxf.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-ws-policy</artifactId>
        <version>${cxf.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-rs-service-description</artifactId>
        <version>${cxf.version}</version>
    </dependency>

If all this didnt help you to solve your issue, the last step is to check your weblogic configuration, here are the steps you have to check on your weblogic server:
