166 +Of course in Java, we may generate WebObjects classes with "get" methods as well in order to stick to convention.
167 +In scala there is an additional convenience we may use to produce "get" and "set" methods in addition to the default Scala accessors - Scala Annotations.
168 +
169 +E.g, in Main.scala we annotate our component keys with ##@BeanProperty## to automatically create public "set" and "get" methods.
170 +These variables can then be accessed via //KVC//.
