Getting - 500 Internal Server Error. The request was rejected by the HTTP filter. Contact the server administrator. (12217)

[ravikumarg17]

I installed jasper server 5.1 on a linux box.

I am able to login with superuser. After login when I try to open the repository tree. like expand organization or Public folder it gives me below message:

Because of this I am not able to configure the Datasource and other custom Datasources which I imported from Dev environment.

"500 Internal Server Error. The request was rejected by the HTTP filter. Contact the server administrator. (12217) "

Another thing I would like to mention is the Tomcat URL is public.

Request to help if there is any configuration through which I could resolve this issue.

In logs below stacktrace is seen:
