We are doing an evaluation of TrackStudio 2.8. So far everything has been great. We have run into a small problem though. We want to create a new users status , but when we do we receive a general TrackStudio error.

We are running on a WebSphere 5.0.2.1 of WebSphere with a DB2 7.1.0.77. I turned debug on and show_sql for hibernate, but the logs are not very interesting in regards to this error.

the SystemErr.log shows a Null pointer exception followed by the gran.exception.GranException: General TrackStudio error


Any help would be great.

thanks

We turned off the show sql for hibernate and left the tackstudio debug on. The system out show this in the log:

We are doing an evaluation of TrackStudio 2.8. So far everything has been great. We have run into a small problem though. We want to create a new users status , but when we do we receive a general TrackStudio error.

We are running on a WebSphere 5.0.2.1 of WebSphere with a DB2 7.1.0.77. I turned debug on and show_sql for hibernate, but the logs are not very interesting in regards to this error.

the SystemErr.log shows a Null pointer exception followed by the gran.exception.GranException: General TrackStudio error


Any help would be great.

thanks

Thank you for the bug report and stack trace. This seems like problem with JCS, I'll try to investigate this problem.

By the way, you can't create user statuses at all or just sometimes ?

Yes, this is problem with JCS. Please try replace jcs.jar with last version from http://www.trackstudio.com/tse-28/jcs.jar.

Some "workarond" - this exception occurs after we create/modify user status and delete all users from cache. So, after you receive this bug you actually have user status created and you can restart server to reinitialize cache.

[kilburb]

I'll give the new jar a try. Just some info we could not create any user status and even if we restarted they did not apear. I'll let you know if this fixes the issue.

Right URL:
http://www.trackstudio.com/tse-28/jcs.jar

If it does not help - please also try
http://www.trackstudio.com/tse-28/trackstudio.jar - I remove invalidateCache call from this version. If it does not help too - let me know, please.

[kilburb]

ok the new jcs.jar did not help, but the new trackstudio.jar fixed the user status change issue. We did find another invalidate problem though. When we try to change the manager of a user it has the same problem, but in this case if we restart the app the change is picked up.

Just wanted to say thanks for helping us threw the eval. I know a lot of other companies would not offer any kind of support let alone a fix.

Hope just fix the bug. Please try new jcs.jar from

Also you should return trackstudio.jar back (take it from distribution).

Just wanted to say thanks for helping us threw the eval. I know a lot of other companies would not offer any kind of support let alone a fix.

Thank you

[kilburb]

Thank you again. That new JCS jar fixed both issues. Everything is working great.
