Hello,

I am getting a strange error when opening a ssl connection to a server. The error occurs both on the simulator and the actual device (BB 8310, V4.5). The first time the connection is established, it functions correctly. When the application exits, the disconnect function is triggered and returns no exceptions. However, when trying to reconnect i recieve the error javax.microedition.io.ConnectionNotFoundException. If I erase the simulator files and run the appliction again it functions correctly, but again, only the first time. I found a post with the same problem but no answer. However, if i run the same application on the 8900 or 9000 simulator or device, the connection functions correctly each time.

private void connect()throws Exception{
     String ipAddress = loadIP();
     String url = "ssl://" + ipAddress + ":9876;deviceside=true";  
     connection = (SecureConnection)Connector.open(url);
     _out = new StringOutputStream (new DataOutputStream(connection.openOutputStream()));
     _out.flush();
     _in = new StringInputStream (new DataInputStream(connection.openInputStream()));
     read = new readThread();
     read.start();
}

public void disconnect(){
     try{
          _in.close();
     }catch(Exception e3){
          System.out.println("_IN.CLOSE() EXCEPTION: "+e3.toString());
     }

     try{
          _out.close();
     }catch(Exception e2){
          System.out.println("_OUT.CLOSE() EXCEPTION: "+e2.toString());
     }
                
     try{
          connection.close();
     }catch(Exception e4){
          System.out.println("CONNECTION.CLOSE() EXCEPTION: "+e4.toString());
     }
                
}

 

 The actual exception is thrown by the line:

connection = (SecureConnection)Connector.open(url);

Don't know whether this'll help, but try tls:// instead of ssl://. Also, make sure you log the connection URL passed into Connector.open just to see whether your app is generating a weird-looking URL the second time the app runs.

Same error occurs whether using tls or sll. The url being passed to Connector.open is no different between successful runs and non successful runs.

I trimmed out all extraneous code to test the connection and the issue still occurs. Here is the entire code that produces the javax.microedition.io.ConnectionNotFoundException in v4.5

import java.io.*;
import net.rim.device.api.ui.UiApplication;
import javax.microedition.io.*;

class TestApp extends UiApplication{
    
   SecureConnection connection = null;

   public static void main(String[] args){
        new TestApp().enterEventDispatcher();
   }
    
   public TestApp() { 
         try{
             connect();
         }catch(Exception e){
            System.out.println("CONNECT 1 ERROR: "+e.toString());
         }
         
         try{
             disconnect();
         }catch(Exception e){
            System.out.println("DISCONNECT ERROR: "+e.toString());
         }
         
         try{
             connect();
         }catch(Exception e){
            System.out.println("CONNECT 2 ERROR: "+e.toString());
         }
   }   

    private void connect()throws Exception{
            connection = (SecureConnection)Connector.open("ssl://10.192.72.131:9876;deviceside=true");
    }
    public void disconnect()throws Exception{
        connection.close();
    }
} 

Output in v4.5:

SSL:<-SKE
SSL:<-SHD
SSL:->CKE
SSL:->CCS

Any help on this would be greatly appreciated!

Interesting!

Try the following two things separately:

1. Add a delay (say, 10 seconds) between the first disconnect() and the second connect().

2. Establish a socket:// connection to the same IP+port, then wrap it into a TLS10Connection using "new TLS10Connection(socketConnection)".

1. The time difference does not appear to have any effect on the appearance of the ConnectionNotFoundException

2.  Exact same behaviour on the 8310. The connection functions as expected the first time, and then any subsequent reconnections fail. The exception given now though is Java.lang.illegalArgumentException. I have verified that the arguments being passed are the same for a successful run and a non successful run. Again, the TLS10Connection functions correctly for each connection on the BB 9000, v4.6

[klyubin]

Where does the IllegalArgumentException occur (Connector.open or TLS10Connection)? Would you please post the stack trace?

P.S. You can obtain the stack trace by catching Throwable instead of Exception. In this case the stack trace will automatically be logged in the EventLog and the Debugger will also break (by default) as soon as the exception is thrown.

IllegalArgumentException occurs at TLS10Connection.

When switching the connection back to:

String url = "ssl://" + ipAddress + ":9876;deviceside=true;";  
connection = (SecureConnection)Connector.open(url);

Here is the stack trace produced when i get ConnectionNotFoundException:

You may want to submit this to RIM's Developer Issue Tracker.
