Occasionally, Jasper Server has an error relating to being unable to write files. The errors show up in the Apache web server log, catalina.out.
You have probably started the service as the user root on accident. This will cause ownership to change to root on some log files. Then when you log back on as user jasper and restart your server, the Apache logs are filling with messages about not being able to write files. Jasper is just not working properly. Run the following command to restore the proper ownership to all files in the Jasper directory. You must run the following command as root:
>find /home/jasper/jasper-server-3.7 -user root -exec chown jasper.jasper {} \;
This will find all the files that root changed ownership and change the ownership back to the proper jasper user.
