WSO2 APIM：管理员应用程序在登录时在BPS中的prolog中生成意外的EOF

时间：2018-06-18 09:36:59

标签： wso2 admin wso2-am wso2bps

我们正在配置WSO2 API管理器（版本2.1.0）以使用Application Creation工作流程。

为此，我们已经配置了BPS节点（版本3.6.0），如中所述 https://docs.wso2.com/display/AM210/Adding+an+Application+Creation+Workflow 另外，我们已完成了所述的调整 https://docs.wso2.com/display/AM210/Configuring+Workflows+in+a+Cluster 这是必需的，因为我们使用2个不同的节点，名称不同。

现在，应用程序创建过程/工作流程似乎工作正常，并且收到并处理了批准和拒绝。

但我们仍然有错误。 当我们登录管理应用程序（https://apimanager.example.com:9443/admin）时，我们在BPS节点中看到错误。

TID: [-1234] [] [2018-06-18 10:36:20,508]  INFO {org.apache.axis2.builder.BuilderUtil} -  OMException in getSOAPBuilder {org.apache.axis2.builder.BuilderUtil}
org.apache.axiom.om.OMException: com.ctc.wstx.exc.WstxEOFException: Unexpected EOF in prolog

我们在做任何事情之前都会看到这个错误，无论如何（没有任务，有待处理的任务和没有待处理的任务）

很明显，admin应用程序在登录时调用WebService，内容错误，但我们不知道如何调试它。我们如何知道在BPS节点中调用哪个服务？

欢迎任何建议。

下面，我们的安装脚本配置工作流程，以及我们正在使用的工作流程扩展
