Dear all

Has any one faced this challenge before, my DHIS2 reports app is not loading. It just shows that its loading but it never completes. Could I have missed out a step somewhere? See image below;

Timothy,  
Please run maintenance and delete war file and name of folder which has the name of your war file. Download a new war and tail -f /path/Catalina.out if there is no error then everything should be fine.

Kindly note I am saying “/path/” because I don’t the path of your logs. Also tomcat must be stop before deleting war file and folder and “tail” the logs before starting tomcat.

Wishing you the best.

Dear Gerald,

This could be also related to your tomcat version, we had the similar issue here in Rwanda with data visualizer, pivot and event report apps not loading after upgrading to dhis 2.24. We have upgraded to our tomcat from 7.052 to 7.0.68 and it worked.

Please trace back Bob,Lars, and Jason discussion on the tomcat version for the new dhis2 releases.

Regards.

Kamugunga,  
If he had provided the logs then that should had been easy to confirm but currently the information seem like a bug on the war file. So the best option is to replace the war file and monitor the logs. If it is a tomcat issue it will definitely show on the logs.

Its hard to say if this is the same issue but it probably is.

The issue is described here

[https://lists.launchpad.net/dhis2-users/msg12117.html](https://lists.launchpad.net/dhis2-users/msg12117.html)

Basically, newer version of Tomcat do not allow for the “|” character in URLs. So, if you have upgraded your operating system to a version which has this version of Tomcat and it does not work you have two choices.

1. Downgrade Tomcat to a version which does work. I beleive 8.0.36 is known to work.

2. Upgrade DHIS2 to a version which fixes this issue, which should be a later build of 2.24, 2.25 or 2.26.

Regards,

Jason

Dear Gerald,

I have tried replacing the war file but the problem persists. See attached my catalina log file. I am working with Tomcat 8.5.8 and DHIS2 2.26. Jason, do I still need to downgrade my Tomcat to 8.0.36? All my apps work except the Event reports app.

Kind regards

Timothy

The important thing to look for is a JavaScript error from the server, namely an HTTP 400 error code. Could you sent your JavaScript console when you load the app?

Timothy,

If you are using the latest version of 2.26, then the more stringent validation of URL characters in recent versions of Tomcat should be supported (for details on the 8.5.x changes, see [http://tomcat.apache.org/tomcat-8.5-doc/changelog.html](http://tomcat.apache.org/tomcat-8.5-doc/changelog.html) )

If your logs still indicate that this is a tomcat issue, try upgrading to tomcat 8.5.11 - if that don’t work then downgrade to 8.0.36

Regards

Calle

From the look of this error, it seems that you have not assigned this user to any organisation units?

I have cross checked and the user is the super user and is also assigned to the parent organisation unit. However, the errors still persist as below when I try to load events reports.
