Igwe,
Public access is not related to Tomcat or web services. It is related to IT infrastucture. If your machine has an IP address accessible from the internet (no firewall, or http port opened), then your deployed service is *de facto* available publically
Check with your network administrator to obtain the answer.
Now about creating a folder and a file,
you should post your question in the Java forum, as it is not specific to web services.
You can also check the java.io.* packahe in the J2SE API
