jprogressbar

I have this program that sends email.I was wondering if i could use progress bar to make user interface better. What i want is that the progress bar should progress accordingly after the statement transport.send() is encountered.Is there a way i can know the progress . What happens know is , as the user presses send a new thread is started that sends the email.The response after clicking send is poor as the user does not know that his action is being listened or not. (though it is being listened !) After a gap of half a minute he gets a JOptionPane that yes , the message has been sent.You will

I have tried tones of different methods to get this to work but they either don't work with a progress bar or don't work the way I would like it to. I have already created a new window with a progress bar and need to create a method which would allow me to download a file while also updating a JProgressBar . There is an Apache Commons method that is extremely easy to use for downloading files but it doesn't seem to be compatible with JProgressBar 's. I have also had trouble when running this in another thread, SwingUtilities.invokeLater doesn't seem to update to progress bar, but it does run

I need a little help with the JProgressBar component. My program copies files from one place to another using java.nio FileChannels . The actual copy method is transferFrom() . I've got two questions now. How to I monitor the transfer progress of FileChannels? All tutorials I've found use the conventional java.io InputStreams and increase the progress int while looping through the inputstream. My copy methods (the FileChannel methods) are encapsulated in a separate method that is invoked by other methods that iterate though source and destination folders and then invoke the FileChannel methods

I have data stored in Jtable, and then I am taking this data row by row and passing this data to a callable procedure in database(1 call for each row), and Procedure returns the message once completed, this process takes almost 1-2 min for each call, can someone tell me how can I display a single progress bar for whole process. (I mean 1 progress bar for all the call), I want Progress bar to be finished once loop ends. My code is below: DefaultTableModel model = (DefaultTableModel) data.getModel(); for (int count = 0; count < model.getRowCount(); count++) { CallableStatement csmt = con

I'm writing a java program and, before I call a method that makes heavy use of the CPU, I display a frame with a JProgressBar on it. Although I display it before the method is called, the JProgressBar is not shown until the method is over. The progress bar does not interact with the method in any way (yet) and that's why I am confused. It is something like: progressbarframe.setVisible(true); // it is a indeterminate progress bar heavyLoadMethod(); progressbarframe.dispose(); The frame shows, but the progress bar doesn't initialize during the method. Is there any way I can solve this without
