You are trying to access Advanced reporting, but receive a 404 error.
In the catalina log file there are a few errors.
Also, Clarity may also be affected and not start as a service (Error Starting Child)
Release : Any
Component : Clarity Jaspersoft
The issue is find Jasper keystore files missing from user's home directory. Jasper Keystore file's are different to Clarity Keystore files which are generated and these files are generated during installation of Jasper Server.
The likely cause of this issue is that you've installed Jasper Server with a different user account and trying to start the service using a different account.
Another possibility is that the Windows Service account doesn't have the ability to access the Keystore in the home directory, due to a server restriction. Ensure that the Windows Service account has rights to get to the home directory specified. As an alternative, the Windows service can be configured to start with a particular user who has rights, but you need to ensure the account's password will not expire, otherwise it will fail to work after a password change.
