How to using read file in FileConnection

[bbonya]

Hi all,

please guide how to using FileConnection in j2me??
I try open and read to file. But don't execute.

An exception happened at InputStream in = conn.openInputStream();

Exception messgae is ..

java.io.IOException:

Code:

import java.io.*;
import javax.microedition.io.*;
import javax.microedition.midlet.*;
import javax.microedition.io.file.*;

public class FileTest extends MIDlet {

	protected void destroyApp(boolean arg0) throws MIDletStateChangeException {
	}
	 
	 protected void pauseApp() {
		 
	 }
 
	 FileConnection conn = null;

	String url = "file:///root1/test.txt";
	
	protected void startApp() throws MIDletStateChangeException {
		try{
			System.out.println("Start app");
			conn = (FileConnection)Connector.open(url, Connector.READ);
		}
		catch(Exception e)
		{
			System.out.println("=== Open error ===");
			System.out.println(e);
		}

		try{
			
			System.out.println(conn);

			InputStream in = conn.openInputStream();

			byte[] b = new byte[1024];
			in.read(b,0,10);
			
			System.out.println(b);
		
		}
		catch(Exception e)	{
			System.out.println("=== Read error ===");
			System.out.println(e);
		}
		
		try{
			conn.close();
		}

		catch(Exception e)
		{
			System.out.println("=== Close error ===");
			System.out.println(e);
		}

	}
}

Everything I could find worked off the tower. ( iow - seems to assume we are going to the internet ) If it is just a local testing and get-going question, then we might do it like this:

Code:

FileInputStream file = new FileInputStream ("test.txt");//
DataInputStream stream = new DataInputStream(file) ;//

Or something similar.

Further questions welcome, it is hard to tell if this is the question it sounds like. Additionally, information may be obtained by trapping the errant code in an exception block, then posting the message it gives.

I find out a solution.

Code:

Enumeration e = FileSystemRegistry.listRoots();

String root = (String)e.nextElement();
String filename = "file:///" + root + filename;

FineConnection fc = (FileConnection)Connector.open(filename, Connector.READ);

InputStream is = (InputStream)fc.openInputStream();

Thanks for the reply.
