public class HelloWorld
extends Object

This example illustrates the use of WebLogic File Services. HelloWorld looks for a file on the server, writes "Hello World" to the file if it is NOT there, reads the first 11 bytes of the file, and displays them.

To run this example, first locate or start a WebLogic Server offering a network-visible file system by setting the property `weblogic.io.fileSystem` in your `weblogic.properties` file. For example, to configure a WebLogic Server to offer the native file system directory /myserver/fullPath as a network-visible file system named myFiles, set the property `weblogic.io.fileSystem.myFiles=/myserver/fullPath` in the server's `weblogic.properties` file.

After compiling this directory, call HelloWorld with three arguments:

- URL of the WebLogic Server
- Name of the file system
- Name of the target file

You may also call HelloWorld with two arguments:

- URL of your WebLogic Server
- Name of the target file

in which case it will use the empty file system name. The empty file system name refers to the local file system on the client. File names are always absolute on a remote file system, but may be relative on a local file system.
