Hello Faizel,

Thanks a lot for this.
I was able to get back to this and made some tests. First, it’s clearly better
when the context.xml file is in META-INF:)
I voluntarily made a typo in it and I was able to see that the file was
actually checked by Tomcat.
I also tried to put things the other way around to actually create the issue on
my test machine (Mac mini), but I wasn’t able to “break” it…
I thought that putting ERExtensions.jar in the PostResources would lead to the
error I was getting on the other tests servers, but everything worked fine on
the Mac mini. I wasn’t able to make it exhibit the failure from the other
servers (NoSuchMethodError). I don’t understand that, and it feels like I can’t
be sure it would work as expected on future deployment.

Any idea why I couldn’t create the error using the Pre/Post Resources (I’ve put
all resources in their opposite directive)?
Any idea on how to make sure I can create (and so fix for sure) the error?

For now, I don’t have access to the other servers that were having the issue,
but I used Matt’s tip (pre-expand ERExtensions.jar into /classes/…) and it was
working. It’s just that I don't feel confortable keeping this solution as
nothing tells me that classes folder loading won’t change in a Tomcat update…

Thanks a lot,

Xavier
