Question

我按照http://aparnaank.blogspot.in/2014/03/how-to-configure-wso2-bps-workermanager.html链接集群WSO2 BPS。当所有服务器启动并且ELB显示两个成员已加入时。

当我点击（试试）网络服务时，我收到以下错误

当你点击试试它时，它调用的URL是什么？

在工作节点中设置代理端口，并参阅

转至/repository/conf/tomcat/catalina-server.xml并按如下方式设置代理端口

<Connector protocol="org.apache.coyote.http11.Http11NioProtocol" 
           port="9763"
           proxyPort="8280"
 
<Connector protocol="org.apache.coyote.http11.Http11NioProtocol"
           port="9443"
           proxyPort="8243"
