尝试使用 jaxws-service 公开服务时出现 Mule3 问题

Question

首先，我使用 CXF 或 Maven 插件中的 WSDL to Java 工具生成 CXF 服务，然后尝试使用 cxf jaxws-service 通过 mule 3 公开服务，如下所示：

<flow name="SoakarService">
    <!-- Public interface -->
    <composite-source>
        <inbound-endpoint address="http://localhost:8777/services/soakar" exchange-pattern="request-response">
            <cxf:jaxws-service serviceClass="com.arcusys.soakar.soap.Soakar"/>
        </inbound-endpoint>
    </composite-source>

    <component>
        <singleton-object class="com.arcusys.soakar.soap.SoakarImpl"/>
    </component>
</flow>

最后我不断得到以下异常：

我使用 mule 3.2 .1.所以 mule-module-cxf 也是 3.2.1。

我尝试指定 wsdl 位置，但什么也没发生，仍然出现相同的异常...

原因是：

java.lang.NoSuchMethodError： org.apache.cxf.common.xmlschema.SchemaCollection.read(Lorg/w3c/dom/Document;Ljava/lang/String;)Lorg/apache/ws/commons/schema/XmlSchema;

mule-module-cxf 看起来有问题。也许 XmlSchema 的版本不相关？

Answer 1

您似乎在类路径上使用了错误版本的 xmlschema，请确保您的 %MULE_HOME% 中有文件 XmlSchema-1.4.7.jar /lib/opt 并且您的类路径中没有其他 xmlschema-core 版本。
