This is the second of the BasicCalcServer series of samples.
It shows two values of String type being passed as arguments to Quotient(), a remote service method.
Quotient()'s parameters are declared to be of type int (not String). WTF?
BTW, parameters appear in procedure definitions; arguments appear in procedure calls. See this discussion.
WebORB "adapts" the method's arguments to match the method's parameters (that is, it converts the Strings to ints).
This is similar to the conversion that WebORB must do to adapt the method's result type (C#'s float to ActionScript's Number).
It is not recommended that you make a habit of passing Strings where ints are expected. The arguments you pass to a remote service method should be of a type that is as closely-related as possible to the type of the method's corresponding parameters.
Things to try:
Enter non-integer or non-numeric strings into the running sample's dividend and/or divisor fields, then press the "=" button.
