Fwd: question about call.invoke

[TC Heiner]

what is the difference between call.invoke in axis 1.2 and 1.4?
why does my code return a 503 (service unavailable) error in 1.2 and not 1.4?

i did a diff between the two source for call.java and only saw some mime differences.

i'm simply sending a soap message with a logon id and password.

i'm sending this out hoping one of the developers on the project can clue me in.

thanks.
