+---- In comp.lang.java.help, you wrote:
| I would like for one execution of my appl'n to "lock" a file such that

Me too. At least advisory locking. Entire files if necessary.

| I have not yet seen any support for such an action.

Me either. At least not from java.*.

| Any help would be appreciated.

As this sort of thing is critical to servers that cooperate
with other processes (I've written things like sendmail
replacements in Java, but I don't want to lose mail so I don't
use them for anything other than testing), there is hope that
someday Sun/Javasoft will spec such things.
