Hi Amit,
Try that one
def bindObject[T <: AnyRef](className: Class[T]): Option[Object] = {
val sClassName =
className.getPackage.getName.concat(".Wrap".concat(className.getSimpleName))
try {
Some(Class.forName(sClassName.replaceFirst("com.vtech",
"com.vtech.appxtension")).newInstance.asInstanceOf[T])
} catch {
case e: Exception =>
try {
Some(Class.forName(className.getName).newInstance.asInstanceOf[T])
} catch {
case e1: Exception =>
println(e1.printStackTrace)
None
}
}
}
Regards,
Sergey
