Blank cockpit and tasklist

[sanjay....@gmail.com]

I just upgraded from 7.2.0 to 7.3.0, restructured the database using the provided sql scripts, and started up (with no other changes).

The camunda-welcome page appears correctly (showing the three thumbnails for tasklist, cockpit, and admin). But clicking on tasklist or cockpit just opens a blank page.

I have tried clearing the browser cache, but there is still no improvement. The logfiles all look normal (no ERROR lines).

What else can I check? I am using the Tomcat distribution on Ubuntu 14.04. My previous setup (with 7.2.0) worked on the same computer with no other changes.

Thanks for any help.

Hi

Depending on your browser, if you can open the javascript console associated with the browser, see if there are any errors in the browser console...

Indeed, there are a bunch of lines like the following:

http://ec2-54-68-91-14.us-west-2.compute.amazonaws.com:8080/camunda/app/cockpit/$APP_ROOT/app/cockpit/styles/styles.css
Failed to load resource: the server responded with a status of 404 (Not Found)

The "$APP_ROOT" looks suspicious, should it have been translated into something?

Thanks for the lead.

Hi,

Did you also upgrade your webapp from 7.2 to 7.3?

Cheers,

Roman

Sorry, I mean did you also upgrade the camunda-bpm-webapp from 7.2 to 7.3?

Hi, Thanks for your help. I'm not sure what you mean, but here is what I did:

1) Downloaded the 7.3.0-Final Tomcat distribution from http://camunda.org/download/ and extracted the zip
2) Changed the database drivers and url to point to a MySQL database
3) Started the server

I did exactly the same things for 7.2.0 also (except for downloading a different zip in step 1 above). The changes I made in step 2 are the same for 7.2.0 and 7.3.0.

Is there anything else that should have been changed?

Thanks again.

A fresh reinstall seems to have taken care of the problem, so it must have been an error in some of the manual changes in the conf directory (for using a different database).

Thanks.
