Controller URL not accesable

Hi,

My controller and databases servers are working fine but I am not able to open my Contoller UI.

and I see the following error when I try to reach the URL locally.

[root@myscislin-0069 ~]# curl -i localhost:8090
HTTP/1.1 500 Internal Server Error
X-Powered-By: Servlet/3.0 JSP/2.2 (GlassFish Server Open Source Edition 3.1.2.2 Java/Oracle Corporation/1.7)
Content-Length: 0
Date: Thu, 07 Jan 2016 10:04:44 GMT
Connection: close

Can anyone let me know what may be the issue and how can I overcome it. Thanks for your help.

Thanks,

Sri Naresh
