[opencms-dev] setContents() and writeFile() not enough to save?

[jill]

In case anyone is interested in the solution, it was punting in an exception
somewhere down the line for not locking the resource before I saved it.  I
was hoping that I could implement the bare bones of WebDAV first and
introduce locking later, but OpenCms was at least expecting me to lock
before writing the file.  Fair enough.
