NullPointerException an WinXP

Hello,

I just tried to get the 1.2.1 release of mango running on a WinXP-Platform.

I use SUN-Java 1.6.0 Update 6 and Tomcat 6.0.16. Tomcat is running fine.
I installed Mango in ROOT, as described an the Download Page. Later on I want to have it in a seperate PATH, but at first it should run.

When restarting Tomcat after unpacking the files I get the following error mesage in the "localhost.....log"-File:

Somebody any hint, what is going wrong? I can provide the other losfiles too, if they help.

Hi Martin,

Thanks for reporting this. It appears that Mango couldn't find its script for creating a fresh database. Can you please check whether this file exists: 'WEB-INF/db/createTables.sql'. We will continue to check for other possible causes.

Hi Martin,

This is apparently a problem introduced with Tomcat 6.0.16, at least in the sense that 6.0.14 was too permissive. We will create a fix for this for the next version of Mango. In the meantime you can use Tomcat 6.0.14, which you can download from the Mango download page.

Hello,

thanks. It's now running on TomCat 6.0.14 without problems.

Regards
Martin
