在wso2esb中创建JMS配置时出错

Question

我使用的是wso2esb4.7.0和wso2mb-2.2.0。我希望使用wso2mb创建jms代理服务。为此，我配置了wso2mb和wso2esb，类似于：

Wso2esb配置：(jndi.properties中的更改)

# register some connection factories
# connectionfactory.[jndiname] = [ConnectionURL]
 connectionfactory.QueueConnectionFactory = amqp://admin:admin@clientID/carbon?brokerlist='tcp://localhost:5673'
 connectionfactory.TopicConnectionFactory = amqp://admin:admin@clientID/carbon?brokerlist='tcp://localhost:5673'


# register some queues in JNDI using the form
# queue.[jndiName] = [physicalName]
queue.MyQueue = MyQueue

axis2.xml中的更改：

取消注释以下代码：

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

 <transportReceiver name="jms" class="org.apache.axis2.transport.jms.JMSListener">
        <parameter name="myTopicConnectionFactory" locked="false">
           <parameter name="java.naming.factory.initial" locked="false">org.wso2.andes.jndi.PropertiesFileInitialContextFactory</parameter>
            <parameter name="java.naming.provider.url" locked="false">repository/conf/jndi.properties</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.wso2.andes.jndi.PropertiesFileInitialContextFactory</parameter>
            <parameter name="java.naming.provider.url" locked="false">repository/conf/jndi.properties</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.wso2.andes.jndi.PropertiesFileInitialContextFactory</parameter>
            <parameter name="java.naming.provider.url" locked="false">repository/conf/jndi.properties</parameter>
            <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">ConnectionFactory</parameter>
            <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
        </parameter>
    </transportReceiver>

还将andes-client-*.jar和geronimo-jms_1.1_spec-*.jar从$MB_HOME/client-lib复制到$ESB_HOME/存储库/geronimo-jms_1.1_spec-*.jar/lib

重新启动servers.Till --它很好用。

现在希望创建一个带有jms端口的服务。它正在创建一个服务，但它马上就会转到错误的服务和esb日志中，显示错误，如下所示：

 ERROR - JMSListener Unexpected error when configuring service SampleJMS for the JMS transport. It will be disabled for this transport and marked as faulty.
java.lang.NullPointerException
    at org.apache.axis2.transport.jms.JMSListener.getConnectionFactory(JMSListener.java:132)

    at org.apache.axis2.transport.base.AbstractTransportListenerEx.start(AbstractTransportListenerEx.java:83)

此外，当重新启动它时，会显示错误，例如：

错误-名称org.apache.axis2.transport.base.BaseTransportException: ConnectionFactory的BaseUtils JNDI查找返回了一个org.wso2.andes.client.AMQQueue，而接口javax.jms.ConnectionFactory预期为2015-01-20 :22:27,709错误- ListenerManager无法初始化jmstransport侦听器ConnectionFactory JNDI查找名称ConnectionFactory返回一个org.wso2.andes.client.AMQQueue，而接口javax.jms.ConnectionFactory是预期的

我的代理配置是：

  <target> 
      <inSequence> 
         <property name="Action" 
                   value="urn:placeOrder" 
                   scope="default" 
                   type="STRING"/> 
         <log level="full"/> 
         <send> 
            <endpoint> 
               <address uri="http://localhost:9000/services/SimpleStockQuoteService"/> 
            </endpoint> 
         </send> 
      </inSequence> 
      <outSequence> 
         <drop/> 
      </outSequence> 

为什么会这样呢？他们的jms配置有什么问题吗？请引导我。

Answer 1

在jndi.properties中，您定义了：

• QueueConnectionFactory
• TopicConnectionFactory

在axis.xml中，您可以使用：

• QueueConnectionFactory
• TopicConnectionFactory
• 并且，在默认的部分中，"ConnectionFactory“

我不使用WSO2MB，我不知道这是不是你的问题
