Subject RE: My small, simple problem continued... (null container for my valve)
Date Tue, 10 Jul 2001 14:59:49 GMT
All right, I think I figured it out, and it seems a little strange. I was
checking to see what the container for my valve was, in the
_constructor_...the constructor is getting called before any of the
heirarchy tree is built, it seems. Does Catalina load up components and run
constructors in-order, rather than pre-order?

One odd question, though...when IS the invoke method of a valve called?

In the lib folders, you can only put jars. Un-jarred classes should be in
the classes folders. That's mentioned in the CL docs.

The best place to put your valve here is in server/classes/

Does your valve extend ValveBase or implement Contained ?
