Answer 1

A file access URL starts with "file://"...

Answer 2

You have to write the path like

file:///NewFile.xml/

try{ 
conn =(FileConnection)Connector.open("file:///NewFile.xml/"); 
if(!conn.exists()) 
  conn.create(); 
_screen.add(new RichTextField("Connection Established...")); 
_screen.add(new SeparatorField());

}
catch(IOException ioe)
{
     _screen.add(new RichTextField(ioe.getMessage()));
}

Getting Started with fileconnection

Answer 3

Use File, and then toUrl()

Answer 4

You do not need a file connection, but can read the data from jar directly by using input stream:

Class.getClass().getResourceAsStream("/NewFile.xml");

Answer 5

add prefix "http://" into your file path or url
