Grouper Users - Open Discussion List

[Colin Hudler <>]

Forget all that. I do see that you've created a custom 
servletFileUpload() to wrap it all with the factory. This stands out:

String tempDir = TagUtils.mediaResourceString("file.upload.temp.dir");

That property has no setting in media.properties. Why would it work in 
the other environments? It can be fixed by giving that a valid value. It 
also fixes my previous report of the problem. I'd love to be able to 
understand what might make it work without that setting, since none of 
the other environments have it either.
