我已经安装了 IBM WAS 网络部署(应用程序服务器)版本 8.0.0 和 IBM portal express 8.0.0。成功创建配置文件后，当我点击两个服务器的 URL 时。 WAS URL 正在运行，我可以登录，但门户 URL 出现以下错误。 网址:
https://localhost:10080/IBM/console

http://localhost:10077/wps/portal - not working and below error on screen

我也尝试过删除“Temp”和“wstemp”文件夹，但这对我不起作用。那你能帮忙吗？
最佳答案
由于两个节点同时启动，我之前曾发生过这种情况。为了解决这个问题，我关闭了两个节点上的 nodeagent 和 Portal 服务器，并一次启动它们。首先是节点代理，然后是门户服务器。一旦开始营业，我就启动了另一个节点。
关于websphere-8 - "Error 500: javax.servlet.ServletException: Filter [PreviewFilter]: could not be initialized"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/50911691/
