Re: Test, Migrating to Turbine 4.0-M1

Sorry for the late reply on this one.

The the error "java.lang.NullPointerException: charsetName" pretty much 
means "something went wrong when starting the webapp". In other words, if a 
webapp really crashes during startup and the error can't be caught, this is 
wat tomcat prints. You can get more specific prints by changing the log 
level in tomcat.

Regarding the encoding in velocityservice we did have a problem with 
configuring it and we solved it by extending the method getTemplateEncoding 
in our RunData object. This is turbines first choice of template encoding.

We do actually use Turbine-4.0-M1 in production. It does work without any 
problems once it's up and running. The things that (IMO) disqualifies it as 
an official production release are configuration errors like the one 
mentioned above. Therefore, doing the migration can take a while but it is 
definetly doable.

Great. We'll try to support you as much as possible.

Yes.

The base version is 2.4 with modern modifications (read: after 2.3)
forward ported.

Yes. Almost all base services have been replaced by Fulcrum Avalon
components. I suggest to follow
http://wiki.apache.org/turbine/Turbine4/Turbine4.0M1/Migrate233 to see
all modifications that need to be made. Especially, please be aware of
the Gotchas section at the end of said document.

This problem appeared in the first RC of 4.0_M! but has apparently been
fixed by Ludwig Magnusson before we released M1. Maybe he cares to comment?

This should not happen in regular Turbine code. Could you provide a
stack trace?

Bye, Thomas.
