Hi! Currently I'm developing an application which will deal with the http connection. For the http connection, I will send out my request to download an image. The problem I'm facing right now is when there's no response back for my request, my whole application is hang. I totally unable to exit the application and need to reset the device all the time. Here, I would like to ask whether is there anyone can help me to handle the no response back for the http connection. I'm using the below method for my http connection.

HttpConnection connection = null;
connection = (HttpConnection)Connector.open(url,Connector.READ_WRITE);
DataInputStream iStrm = connection.openDataInputStream();
ByteArrayOutputStream mSrm = null;
int length = (int) connection.getLength();
mData = new byte[length]; mSrm.readFully(mData);

After opening the connector, I need to close the connector when receiving the response back from my request. If there's no response back, my connector is always open and this cause my application hang.

Is there way to close the connector if there's no response back from the request made to http connection?

Please help....

what you need to do is create a new thread and call http connection in the new thread. this way you can have multiple concurrent downloads happening as well as controls to terminate or interrupt each of those threads individually. you might also want to tie a progressbar to each of those threads for a visual effect showing the progress of the downloads, but you will probably need to implement swing worker pattern which may not be available to you depending on the version of the jvm you are running, ie has to be > 1.2.x
