Question

我正在尝试在WSO2 ESB 5.0.0中使用ActiveMQ配置JMS传输。我已按照https://docs.wso2.com/display/ESB500/Configure+with+ActiveMQ中的说明操作，但没有成功。

我的ActiveMQ版本是5.10。

当我通过JMS Endpoit发送消息时，我收到此错误：

TID: [-1234] [] [2016-10-11 17:42:15,618] ERROR {org.apache.synapse.core.axis2.Axis2Sender} - Unexpected error during sending message out {org.apache.synapse.core.axis2.Axis2Sender}

我们使用XA Transaction时会抛出此异常。否则它可以正常工作。

任何帮助？

Answer 1

如果使用ActiveMQ 5.10，则需要将/ lib目录放入 / repository / components / lib目录下列文件：

activemq-broker-5.10.0.jar
activemq-client-5.10.0.jar
geronimo-j2ee-management_1.1_spec-1.0.1.jar
geronimo-jms_1.1_spec-1.1.1.jar
hawtbuf-1.10.jar

不是https://docs.wso2.com/display/ESB500/Configure+with+ActiveMQ

中列出的文件

Answer 2

ActiveMQ有一个XA连接工厂：

指定：org.apache.activemq.ActiveMQXAConnectionFactory

Answer 3

在使用Active MQ版本5.10时，必须将以下来自版本5.8的jar添加到$ ESB_HOME / repository / components / lib中。

activemq-broker-5.8.0.jar
ActiveMQ的客户端 - 5.8.0.jar
的geronimo-jms_1.1_spec-1.1.1.jar
Geronimo的J2EE的management_1.1_spec-1.0.1.jar

在/repository/conf/axis2/axis2.xml中取消注释JMS传输侦听器和JMS传输接收器。

<transportReceiver name="jms" class="org.apache.axis2.transport.jms.JMSListener">
   <parameter name="myTopicConnectionFactory" locked="false">
       <parameter name="java.naming.factory.initial" locked="false">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
       <parameter name="java.naming.provider.url" locked="false">tcp://localhost:61616</parameter>
       <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">TopicConnectionFactory</parameter>
        <parameter name="transport.jms.ConnectionFactoryType" locked="false">topic</parameter>
   </parameter>

   <parameter name="myQueueConnectionFactory" locked="false">
       <parameter name="java.naming.factory.initial" locked="false">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
       <parameter name="java.naming.provider.url" locked="false">tcp://localhost:61616</parameter>
       <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">QueueConnectionFactory</parameter>
        <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
   </parameter>

   <parameter name="default" locked="false">
       <parameter name="java.naming.factory.initial" locked="false">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
       <parameter name="java.naming.provider.url" locked="false">tcp://localhost:61616</parameter>
       <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">QueueConnectionFactory</parameter>
        <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
   </parameter>

<transportSender name="jms" class="org.apache.axis2.transport.jms.JMSSender"/>

然后启动服务器。

您必须根据您的方案检查配置[1]。

当ESB发送到jms端点时，示例代码如下：

<proxy xmlns="http://ws.apache.org/ns/synapse" name="StockQuoteProxy" transports="http">
 <target>
    <inSequence>
        <property action="set" name="OUT_ONLY" value="true"/>
        <send>
            <endpoint>
                <address uri="jms:/SimpleStockQuoteService?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&amp;                 java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory&amp;java.naming.provider.url=tcp://localhost:61616&amp;transport.jms.DestinationType=queue"/> 
            </endpoint>
        </send>
    </inSequence>
    <outSequence>
        <send/>
    </outSequence>
    </target>
    <publishWSDL uri="file:repository/samples/resources/proxy/sample_proxy_1.wsdl"/>
   </proxy>

您的错误指示有关JMS发件人的问题。特别检查axis2中的配置以及定义jms端点的代理配置。
