WSO2 ESB work with MB

Question

我试图将消息从本地客户机发送到ESB，并将其重定向到同一服务器上的MB。客户端正在等待响应，直到应用服务器抛出错误。

我的环境如下WSO2 ESB 4.8.0(端口偏移量1)WSO2 mb2.1.1(端口偏移量2)IBM WebSphere Application Server 8.5.5.1

ESB的代理服务配置

<proxy name="SMSQProdProxy" transports="http" startOnLoad="true" trace="enable">
    <target>
        <inSequence>
            <property name="OUT_ONLY" value="true"/>
            <send>
                <endpoint>
                    <address uri="jms:/SMSQ?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&amp;java.naming.factory.initial=org.wso2.andes.jndi.PropertiesFileInitialContextFactory&amp;java.naming.provider.url=repository/conf/jndi.properties&amp;transport.jms.DestinationType=queue"/>
                </endpoint>
            </send>
         </inSequence>
         <outSequence>
            <send/>
         </outSequence>
    </target>
    <publishWSDL key="gov:/trunk/services/SendToSMSQProxy.wsdl">
       <resource location="SMSWSService_schema1.xsd"
               key="gov:/trunk/services/SMSWSService_schema1.xsd"/>
    </publishWSDL>
</proxy>

应用服务器错误日志

. io .Async IO操作失败(3)，reason: RC: 55

谢谢你的建议。

添加<property name="FORCE_SC_ACCEPTED" value="true" scope="axis2"/>后，我得到另一个错误消息

有一个类似的问题https://wso2.org/jira/browse/WSAS-1214

Answer 1

您可以将OUT_ONLY属性添加到您的in序列之后，以返回到客户端。此属性将强制ESB使用HTTP 202响应客户端。

<property name="FORCE_SC_ACCEPTED" value="true" scope="axis2"/>

Answer 2

似乎您遇到的新错误与MB集成流程无关。是否在会话超时后访问管理控制台?你能不断重复这个问题吗?或者这只是一次发生?

Answer 3

当您将OUT_ONLY属性设置为true时，您正在说，您不等待代理结束后的响应。因此，在outSequence中去除send介质。

如果要强制代理向客户端发送响应，请删除Out_Only属性，并且在inSequence节中将此设置在endPoint中介人之后。

property name="FORCE_SC_ACCEPTED"  value="true"  scope="axis2"  type="STRING"

在outSequence部分保留<send/> mediator…
