Installation Problem with Linux + MySQL


I have installed Code Collaborator on a Linux server with this characteristics

Linux 2.6.18-194.el5 #1 SMP x86_64 x86_64 x86_64 GNU/Linux Red Hat

Code Collaborator version 7.3.7302

MySQL: mysql  Ver 14.14 Distrib 5.1.63, for unknown-linux-gnu (x86_64) using readline 5.1

Copyright (c) 2000, 2011, Oracle and/or its affiliates. All rights reserved.

So, install runs fine, it finds the database no problems. After the install the application starts. At this point I connect via browser to http://<server>:8080 - immediately it redirects to the /ui folder. It indicates that DB is empty and that it requires initialization.

As soon as I click I get this error:

"A critical error occurred while upgrading the database: null Please contact Customer Support".

The tables in the db are created but the system does not continue. Do you have any clues on what could be the problem?

Best regards

  • Hi Claudia,

    Are you using an Oracle JDK? We don't support OpenJDK.

    Are you upgrading from a previous version of CodeCollaborator or is this a fresh install?

    We'd actually like for you to contact us at Technical Support, because we will need to look at your server logs.

    Please send us all of the contents of these directories:


    <collab install dir>/tomcat/conf/Catalina/localhost/*

    <collab install dir>/tomcat/logs/*

    <collab install dir>/*.log

    Our email address is


  • This is a fresh install, the VM server was just setup exclusively for this.

    This is what I have on the server:

    java -version

    java version "1.7.0_09"

    Java(TM) SE Runtime Environment (build 1.7.0_09-b05)

    Java HotSpot(TM) 64-Bit Server VM (build 23.5-b02, mixed mode)

    I will send logs to you via email

    Best regards
