Hi Joe, "_" is acceptable for a node name. I don't really know what you could be referring to.
I frequently use http://jcr.day.com to validate things like that. http://jcr.day.com/ exposes a public test web gui on top of JCR and lets you perform all the JCR calls by "clicking buttons" ;) I created a node "_" in the default workspace and queried for it, everything seems to work as expected. You can go to the "Content Explorer" to test things if you like. regards, david On 4/19/07, Ottinger, Joseph <[EMAIL PROTECTED]> wrote:
