mysql - JSF webApplication - glassfish 服务器遇到内部错误

Question

简而言之:

[当我尝试创建新的 JDBC 连接池时，glassfish 管理控制台出现问题]

有人可以帮我解决这个问题吗:

首先，我想在 Netbeans IDE 8.1 上开发一个 JSF 应用程序

当我填写创建新 JDBC 连接池 的页面时，glassfish 控制台会抛出此异常:

type : Exception report

message :Internal Server Error

description : The server encountered an internal error that prevented it from fulfilling this request.

exception : 

java.lang.IllegalStateException: getOutputStream() has already been called for this response

note : The full stack traces of the exception and its root causes are available in the GlassFish Server Open Source Edition 4.1.1 logs.
