Subversion supports what you want to do by passing it something called a
"Peg revision". In your case, the peg revision would be 298, since the
file still existed at that revision. This feature was added post 1.0, so
not all of the JavaHL API's have it exposed to us, although I think there
might be diff API's now where it is. Anyway, if you do not pass an
explicit peg revision, then Subversion defaults to HEAD. The second
problem, is that if the API does support peg revisions, all we can do is
infer it from what you enter, since we would not want to add fields for it
to the UI.

One thing you can try that might work, but probably will not, is to
specify the URL like this:


That is the command-line syntax for specifying a peg revision. I do not
think the library API supports that syntax, which is why I do not think it
will work.
