I have a thread which makes HTTP requests and the code ensures that at most 2 simultaneous connections are made at any one time. However, I get IOExceptions which say "Max connections opened".

I am closing connections cleanly. Does anyone have any ideas on this?

I am using midp1.1 and the 7290.

Thanks.

When does it happen?

Try to open and close the connection 11 times. If you get the max connection happening on the 11 try, then you are probably not closing them correctly.

20 is the max amount of HTTP connection allowed.

Its quite random how it happens.

I am pretty sure i close the connection properly. I first close the input stream and then the connection. Is this the correct way?

It should look something like this:

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

String url = "http://www.google.com";
HttpConnection conn = null;
InputStream in = null;

try {
    conn = (HttpConnection) Connector.open( url );
    int rc = conn.getResponseCode();
    if( rc == HttpConnection.HTTP_OK ){
        in = conn.openInputStream();
    }
}
catch( IOException e ){
    System.out.println( "IOException: " + e.toString() );
}
catch( Exception e ){
    System.out.println( "Exception: " + e.toString() );
}
finally {
    if( in != null ){
        try { in.close(); } catch( IOException e ){System.out.println( "IOException: " + e.toString() );}
    }
    if( conn != null ){
        try { conn.close(); } catch( IOException e ){System.out.println( "IOException: " + e.toString() );}
    }
}

I assume the HTTP connection happens in a separate thread so it could easily be missed.

Try using the JDE debugger to view more info.

Yep, that's what i have.

My application polls (lets call it fetch) a servlet in a thread. So it does a fetch and sleeps for 1000ms and then fetches until the app terminates. While this is going on the user can make a new send request. But i always ensure that i only have 2 simultaneous connections at most. Yet i still get max connections.

Does that sound bad?

What kind of things should i be looking out for in the debugger?

(thanks for your help)

[eradis]

Use the JDE to look at all the threads. I'm sure there is an error in there somewhere (in the threading connection).

Is this happening in the simulator? If yes then for sure there is a logic error. If only on the device, make sure you are running the latest device code.

[rr99bb]

Will try that, it only happens for the device. I have the latest os from vodafone.
