Web App Birt integration + Weird Driver Error

mdelapenya

Hello everybody!

I have this problem: I'm coding some reports on my laptop (Ubuntu 12.04), and all of them works well (as expected). But when I deploy them to production (Windows XP - small customer), only one of them fails.

I have integrated BIRT in a Java web application:

- I've a BirtServlet and BirtEngine classes in my App.
- I've copied MySQL driver in WEB-INF/platform/plugins/org.eclipse.birt.report.data.oda.jdbc_2.6.2.r262_v20110127/drivers
- I've MySQL driver too in Tomcat7/lib folder

It is a weird error, because it relates to database, drivers, etc, but all of the reports should fail then because of this error, and in my case only one fails.

Help needed please!

There is nothing different about this report's db connection? Using JNDI or connection profile?
