MobileFirst服务器错误

Question

尝试诊断MobileFirst服务器错误。 v6.3，Liberty，Windows。

我们有两台假定相同的服务器，一台很好，一台出现故障。

症状：服务器启动，但尝试填充运行时的初始列表时，控制台报告服务器错误。 进一步调查，我们发现尝试调用管理员服务。

因此，我们尝试直接从浏览器调用该服务。 在工作的服务器上，我们看到

{"projects":
 [{"name":"DM","link":"https://shqomfas01.dm.gov.ae:9443/wladmin/management- apis/1.0/runtimes/DM","numberOfAdapters":16,
 "numberOfApplications":2,"synchronizationStatus":"ok",
 "numberOfActiveDevices":0,"numberOfDecommissionedDevices":0,
 "running":true}],"productVersion":"6.3.0.00-20141127-1357"}

在另一台服务器上，我们收到错误响应，并在日志中看到这些异常。

我们今天看到了这个问题。 我们最近对server.xml文件进行了配置更改，并且在登录Worklight Console后收到了“服务器错误”消息。

重新安装运行时解决了我们的问题。
