I've looked around this problem but I do not know how to fix it... Many answers talk about servlet configuration error, but do not say how to fix it and what to change. My catalina log file looks like this:

What do I have to change?
Always look at the bottom of the stack trace to find the root cause. In your case, it is the below exception. It points to some datasource connection and determines the database type when initializing. You probably need to check the database connection properties in your configuration.
