Re: URGENT: T4.1.1 on Oracle OC4J 9.0.4, 10.1.2.xxx - Missing classpath resource '/dojo' issue

[Jan Vissers]

Reading specification of getResource() ...

http://java.sun.com/j2se/1.4.2/docs/api/java/lang/ClassLoader.html#getResource(java.lang.String)
"Finds the resource with the given name. A resource is some data 
(images, audio, text, etc) that can be accessed by class code in a way 
that is independent of the location of the code."

What I am seeing here is that getResource(java.lang.String) on a 
"directory" contained in a jar file, will result in "null" (on OC4J 
9.0.4/10.1.2.xxx).
Does this mean that Oracle has taken spec very strictly and doesn't 
"allow" directories being "get" like this?

You can try messing with that or searching oracle related things for
configuring / changing the classloader settings.  Tapestry will 
ultimately
defer class (and class resource) resolution up to whatever class 
loader it
is running in - so it clearly has to be something oracle is f$#-ing up -
again.

'/dojo/' is in tapestry-framework-4.1.1.jar - maybe I am missing some
basic understanding here, but
why the hell is '/dojo' not found?
