Is there any way in J2ME to get sim card number, Is there any Nokia APIs to interact with nokia devices resources as cam flash or voice level buttons or ...etc.
Can we integrate C++ code (Qt code) with Java code (J2ME)?
You can use the Java Native Interface to wrap non-java code such as C++ into Java classes.
As far as Nokia APIs go, I'm afraid you'll have to check their developer documentation.
One of the most odious afflictions that Business has inflicted on the modern English language is "pro-active". Most of the time it's simply redundantly used in place of the simple old word "active". And a good deal of the rest of the time it means "You're not overworked enough yet, so go out and find more!"
