7 -- Makes a http request to a java servlet. Parses the returned HTML
8 -- page and stores the values in the OUT parameters.
9 -- p_result is the value returned from the java servlet.This is
10 -- usually true or false, but it may also be error codes.
11 -- If the java program had any other information to return, these are
12 -- returned as a PL/SQL table of name-value pairs.
13 -- If the call failed, then the errors from the error stack are
14 -- returned in a PL/SQL table of encoded messages.
15 -- The caller should call fnd_message.set_encoded and fnd_message.get
16 -- to get the entire translated message.
