WSO2 ESB 5.0上的运行时错误

我正在尝试使用WS02 ESB 5.0每15秒调用一次Web服务，所以我有这个任务：

<?xml version="1.0" encoding="UTF-8"?>
<task class="org.apache.synapse.startup.tasks.MessageInjector"
group="synapse.simple.quartz" name="UpdateName" xmlns="http://ws.apache.org/ns/synapse">
<trigger cron="0/15 * * * * ?" />
<property name="message"
xmlns:task="http://www.wso2.org/products/wso2commons/tasks">
<def:login soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:def="http://DefaultNamespace" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<id xsi:type="xsd:string">usr</id>
<pw xsi:type="xsd:string">pwd</pw>
</def:login>
</property>
<property name="sequenceName" value="main"
xmlns:task="http://www.wso2.org/products/wso2commons/tasks" />
<property name="injectTo" value="sequence"
xmlns:task="http://www.wso2.org/products/wso2commons/tasks" />
</task>

这个序列：

<?xml version="1.0" encoding="UTF-8"?>
<sequence name="main" xmlns="http://ws.apache.org/ns/synapse">
<in>
<send>
<endpoint>
<wsdl port="SakaiLogin" service="SakaiLoginService" trace="disable"
uri="http://myserver/sakai-axis/SakaiLogin.jws?wsdl" />
</endpoint>
</send>
</in>
<out>
<send />
</out>
<log level="full" />
</sequence>

两者都来自文档中显示的示例： https://docs.wso2.com/display/ESB500/Adding+and+Scheduling+Tasks（请参阅“将消息注入指定的序列或代理服务”）。 https://docs.wso2.com/display/ESB500/Sample+56:+Using+a+WSDL+Endpoint+as+the+Target+Endpoint（参见“构建示例”）。

但是，一旦启动Carbon WSO2 ESB服务器，我就会收到此错误：

有人能告诉我发生了什么事吗？ 非常感谢！

答案 0 :(得分：2)

在wsdl端点中，uri值必须是WSDL地址，而不是服务端点：

<?xml version="1.0" encoding="UTF-8"?>
<task xmlns="http://ws.apache.org/ns/synapse"
      name="UpdateName"
      class="org.apache.synapse.startup.tasks.MessageInjector"
      group="synapse.simple.quartz">
   <trigger cron="0/15 * * * * ?"/>
   <property name="proxyName" value="testTask"/>
   <property name="message">
      <moc:QRY_SELECT_SRH_EMPLEADO xmlns:moc="http://www.example.org/mockWS/">
         <INT_ID>gero et</INT_ID>
      </moc:QRY_SELECT_SRH_EMPLEADO>
   </property>
   <property name="soapAction"
             value="http://www.example.org/mockWS/QRY_SELECT_SRH_EMPLEADO"/>
   <property name="injectTo" value="proxy"/>
</task>

因此，send mediator中的WSDL端点使用服务和端口名称从WSDL文档中提取服务端点，以在wsdl文档中找到它。

更新1：

我的任务配置xml：

<?xml version="1.0" encoding="UTF-8"?>
<sequence xmlns="http://ws.apache.org/ns/synapse" name="main1">
   <in>
      <header name="Action" scope="default" value="http://www.example.org/mockWS/QRY_SELECT_SRH_EMPLEADO"/>
      <send>
         <endpoint>
            <wsdl service="mockWS"
                  port="mockWSSOAP"
                  uri="http://localhost:8088/mockmockWSSOAP?wsdl"/>
         </endpoint>
      </send>
   </in>
   <out>
   <log level="full"/>
<drop/>
   </out>
</sequence>

我的序列名为main1：

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="testTask"
       transports="https http"
       startOnLoad="true">
   <target>
      <inSequence>
      <header name="Action" scope="default" value="http://www.example.org/mockWS/QRY_SELECT_SRH_EMPLEADO"/>
      <send>
         <endpoint>
            <wsdl service="mockWS"
                  port="mockWSSOAP"
                  uri="http://localhost:8088/mockmockWSSOAP?wsdl"/>
         </endpoint>
      </send>
      </inSequence>
      <outSequence>
         <log level="full"/>
         <drop/>
      </outSequence>
      <faultSequence/>
   </target>
</proxy>

最后我创建了一个具有相同逻辑的代理，因为序列中的drop mediator存在问题：

Private Sub CommandButton1_Click()
Dim firstnum, secondnum As Single
firstnum = Cells(1, 1).Value
secondnum = Cells(1, 2).Value
If firstnum > secondnum Then
MsgBox " The first number is greater than the second number"
If firstnum < secondnum Then
MsgBox " The first number is less than the second number"
Else
MsgBox " They are euqal "
End If

End Sub
