I would say that oracle hasn't interpreted the specification strictly but incorrectly. Ie they are wrong and fuc#$ up - again.
I've been doing this kind of resource loading for years - loading icons and such from swing applications as well as variety of others. I've managed to keep oracle out of my software except when it comes to storing/retrieving relational data so I've not ever run in to this problem. On 5/30/07, Jan Vissers <[EMAIL PROTECTED]> wrote:
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? -J. Jesse Kuhnert wrote: > I'm not sure.
