Hi Ivan,
I am not a Sun AS Expert, so maybe someone with more expertise in that
area can provide more input, but I can give you an idea of why that
error shows up in TopLink Essentials.
That error occurs when something in the early initialization of the
persistence unit fails. Usually this indicates some kind of packaging
or configuration error. Is it possible there is some earlier error
message in your log file?
