BAPI调用期间的HTTP异常（WSO2适配器）

问题描述：

我正在尝试将SAP BAPI适配器用于WSO2。我可以安装它并为客户端模式使用创建一个有效的配置。BAPI调用期间的HTTP异常（WSO2适配器）

这是用于代理（BAPIProxy）代码：

<?xml version="1.0" encoding="UTF-8"?> 
<proxy xmlns="http://ws.apache.org/ns/synapse" name="BAPIProxy" transports="http" startOnLoad="true" trace="disable"> 
    <target faultSequence="rollbackSequence"> 
     <inSequence> 
      <send> 
       <endpoint name="sap_bapi_endpoint"> 
        <address uri="bapi:/JCOCLIENT01"/> 
       </endpoint> 
      </send> 
     </inSequence> 
     <outSequence> 
      <log level="full"/> 
      <send/> 
     </outSequence> 
    </target> 
</proxy>

我试着再进行试验，我代理的“试一试”的功能。 bapi空空时，我会得到一个空的答案。这似乎是正确的。

但是，当有一些数据得到，我得到了一个例外：

我试图用BAPI适配器4.0.3和4.5.0 M4。是否有其他配置将BAPI配置到WSO2中？有没有解决方法？

在此先感谢。

_ “java.net.SocketTimeoutException：读超时” _ - 似乎很清楚，我。有没有防火墙的方式，你可以ping机器，你可以telnet到端口，是服务器忙：基本的网络调试。 – CodeCaster 2012-08-13 10:04:10

我这是一个网络问题，我会有同样的异常，而没有数据可以得到。但这种情况并非如此。 – 2012-08-13 11:36:15

答

利用FaultSequence查看错误是什么。

<faultSequence> 
<log level="custom"> 
<property name="message" expression="get-property('ERROR_MESSAGE')"/> 
</log> 
</faultSequence>
