Directory structure for the sample app Websockets/echo is incorrect .

the sample web appl
has an incorrect director y structure for the java file /.
ref: [https://github.com/eclipse-ee4j/glassfish-samples/tree/master/ws/jakartaee9/websocket/echo/src/main](url)

directory for the source uses the compound package name
org.glassfish.samples.websocket.echo,
instead of creating a hierarchy of package directories : org/glassfish/samples/websocket/echo

**Suggested solution**

preplace directory
- glassfish-samples/ws/jakartaee9/websocket/echo/src/main/java/org.glassfish.samples.websocket.echo
with
- glassfish-samples/ws/jakartaee9/websocket/echo/src/main/java/org/glassfish/samples/websocket/echo
