Hello All,

We are using EH&S Web interface to display the generated SDS on the web.

We were required to restart the web interface server due to some issue.

However, after the restart, the links to web interface servers are not working.

We are getting java dump which is as mentioned below:

HTTP Status 500 -

type Exception report

message

note The full stack trace of the root cause is available in the Apache Tomcat/7.0.8 logs.

Can anyone please guide here.?

We have tried a lot to solve this error at our end, but we could not resolve this error.

Best Regards,
