我正在尝试访问一个返回String（无输入参数）的简单SOAP Web服务。这是配置XML。
<flow name="SOAPWSFlow1" doc:name="SOAPWSFlow1">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8084" doc:name="HTTP" />
<cxf:jaxws-client operation="getTestName" enableMuleSoapHeaders="true" doc:name="SOAP" clientClass="com.mart.catalog.BestMartCatalogService" port="BestMartCatalogPort"/>
</flow>
执行代码时出现以下错误。感谢您解决此问题的任何帮助。谢谢！
