I am trying to execute javadoc command to get the 3-frame API for the following the packages xxx and
xxx.yyy

			

			The directory structure is
			

			

			api
			

			src
			

			----overview.html
			

			---- xxx
			

			-------package.html
			

			-------XXXClass1.java
			

			-------yyy
			

			---------package.html
			

			---------YYYClass1.java
			

			

			classes
			

			-----xxx
			

			-------XXXClass1.class
			

			-------yyy
			

			---------YYYClass1.class
			

			

			

			The src files have just the package and class declarations
			

			

			package xxx;
			

			import yyy.*;
			

			public class XXXClass1 {
			

			}
			

			

			

			package xxx.yyy;
			

			public class YYYClass1 {
			

			}
			

			

			The javadoc command is executed from the src directory.
			

			

			javadoc -d ../api -overview overview.html -classpath ../classes -sourcepath . xxx xxx.yyy
			

			

			But I am getting the following error
			

			

			Loading source file xxx...
			

			Loading source files for package xxx.yyy...
			

			xxx: Invalid character in input.
			

			xxx: Class or interface declaration expected.
			

			xxx: Invalid character in input.
