怎样做才能在同一个Web容器内同时发布和消费webservice呢？（CXF）

大家好，第一次提问：
利用CXF发布Webservice没有问题，同样只是接受webservice服务也没有问题。但是我这里，只要把他们两个的xml文件配置同时放在web容器内，就报空指针异常，请哪位大哥指点一下：

1、client的配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:util="http://www.springframework.org/schema/util"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans-2.0.xsd 
	http://www.springframework.org/schema/aop 
	http://www.springframework.org/schema/aop/spring-aop-2.0.xsd 
	http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd 
	http://cxf.apache.org/simple http://cxf.apache.org/schemas/simple.xsd 
	http://www.springframework.org/schema/util
    http://www.springframework.org/schema/util/spring-util-2.5.xsd
	http://cxf.apache.org/bindings/soap http://cxf.apache.org/schemas/configuration/soap.xsd 
	http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"
	default-lazy-init="true" default-autowire="byName">
	
	
	<jaxws:client xmlns:jaxws="http://cxf.apache.org/jaxws"
		id="commodityServiceClient" serviceClass="com.XXX.XXX"
		address="${webservice.client.host}/XXXervice">
		<jaxws:binding>
			<soap:soapBinding xmlns:soap="http://cxf.apache.org/bindings/soap"
				mtomEnabled="true" version="1.2" />
		</jaxws:binding>
		<jaxws:dataBinding>
			<bean class="org.apache.cxf.xmlbeans.XmlBeansDataBinding" />
		</jaxws:dataBinding>
</jaxws:client>
</benas>

2. server的配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jaxws="http://cxf.apache.org/jaxws"
	xmlns:soap="http://cxf.apache.org/bindings/soap" xmlns:simple="http://cxf.apache.org/simple"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
            http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
            http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd 
            http://cxf.apache.org/simple http://cxf.apache.org/schemas/simple.xsd
            http://cxf.apache.org/bindings/soap http://cxf.apache.org/schemas/configuration/soap.xsd 
            http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"
	default-lazy-init="false" default-autowire="byName">
	<import resource="classpath:META-INF/cxf/cxf.xml" />
	<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
	<import resource="classpath:META-INF/cxf/cxf-extension-local.xml" />
	<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
	<jaxws:server xmlns:jaxws="http://cxf.apache.org/jaxws" id="configServiceWebServer" serviceBean="#XXXService" address="/XXXService">
		<jaxws:serviceFactory>
			<bean class="org.apache.cxf.jaxws.support.JaxWsServiceFactoryBean" scope="prototype">
				<property name="dataBinding">
					<bean id="xmlBean" class="org.apache.cxf.xmlbeans.XmlBeansDataBinding" scope="prototype" />
				</property>
			</bean>
		</jaxws:serviceFactory>
	</jaxws:server>
</beans>

3. 报出的异常是：

问题已经解决， 问题的关键在于Web容器对多个spring xml配置文件的加载顺序，对于webservice的xml文件，由于其加载时间长，必须放在前面先行加载，这样后面的引用才可以。。。个人再多猜想一下：如果整合成一个大的xml文件，应该就没有这样的问题了。。

补充一下：也就是说发布的webservice和消费的webservice不是同一个webservice。。。

2 楼 yuanqingfei 2008-07-23  

是有原因的： 它消费别人的webservice， 同时提供自己的webservice给别人，这样不是很正常吗？

胡乱猜一下，是否和配置文件加载的顺序有关。正常来说应该先加载server的，并且 server 完全启动起来之后，再加载client的才可以，否则应该会有问题。
不明白你为什么把server/client同时部署到一个web容器里。
