The ole mode takes advantage of a consistent coding style to provide a Java-friendly way to call OLE functions. Invoking an OLE-style Add function from Java looks much like invoking a more traditional Win32-style function:
/** dll.import("OLELIKEMATHDLL", ole) */
private native static int Add(int x, int y);
int sum = Add(10, 20);
// if we got here, Add succeeded.
