New File Dialog
Use this dialog to create a new file within your web service project.
Choose Web Service, Java, JavaScript, or Text.
Choosing Web Service creates a new JWS file (a file with the .jws file extension).
Choosing Java creates a new JAVA file (a file with the .java file extension).
Choosing JavaScript creates a new JSX file (a file with the .jsx file extension).
Choosing Text creates a new TXT file by default; however, you can change the TXT file extension by typing in the text box labeled File extension.
In the File name field, type the name of file and click OK to finish the dialogue.
