wso2 - WSO2ESB - 代理服务定义需要“名称”属性

Question

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 )

我做了所有的细节，但是当我"cepSample.xml"在该位置复制文件时，"wso2esb-4.6.0/repository/deployment/server/synapse-configs/default/proxy-services"我在控制台中收到了这个错误，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

Answer 1

我尝试手动创建代理服务 - 并获取此文件（在 ESB 4.8.1 中。）可能对您有所帮助：
