【问题标题】：WSO2ESB- The 'name' attribute is required for a Proxy service definitionWSO2ESB - 代理服务定义需要“名称”属性
【发布时间】：2013-03-06 17:11:43
【问题描述】：
我在部署此示例时遇到问题：“使用 SOA 进行复杂事件处理和业务规则管理”（链接：http://wso2.org/library/articles/2011/07/complex-event-processing-business-rule-management-soa）
我做了所有细节，但是当我将"cepSample.xml" 文件复制到"wso2esb-4.6.0/repository/deployment/server/synapse-configs/default/proxy-services" 位置时，我在控制台中收到此错误，我不会被部署：
/WSO2/wso2esb-4.6.0/repository/deployment/server/synapse-configs/default/proxy-services/cepSample.xml failed - Continue in fail-safe mode
org.apache.synapse.SynapseException: The 'name' attribute is required for a Proxy service definition

【解决方案1】：
我尝试手动创建代理服务 - 并获取此文件（在 ESB 4.8.1 中。）
可能对你有帮助：
