There is no access to arbitrary java classes from Velocity, but you can call methods of existing objects. In the context of Maven archetype you can use methods from java.lang.String and a Velocity loop to get the job done.

#macro( ccase $str )
#foreach( $word in $str.split('-') )$word.substring(0,1).toUpperCase()$word.substring(1)#end
#end
#set( $classNamePrefix = "#ccase( $artifactId )" )

public class ${classNamePrefix}Application {
    // ...
}

If you are using a fileSet tag, add filtered="true" property to make sure source files are processed with Velocity.
