Reflect Copying process with progress bar and percentage

Question

I am using ZK freamework.

I am preparing a project which copies Data from one server and pastes Data to another server. Till end project is working fine and even this is doing the work as per my expectations. I want to show a process bar with the percentage of data copying process. I am using ZK framework, Java Spring, and Mysql.

My requirement is to show the percentage of copying done and a progress bar in zk Framework. please help me through this.

Thanks in advance.

for(long j=1;j<=rowCount;j++){          
    sum = sum + j/rowCount;
    if(j==rowCount){                
    sum=100;
}   
progressMeter.setValue(sum);            
countLabel.setValue((rowCount-1)+" Rows are inserted");
BindUtils.postNotifyChange(null, null, countLabel, "_value");

Beside mine comment,
I would like to point you to a small talk of Robert Wenzel.

He has written some code to simplify long operations and make the updating of the screen easier.

Check it out and maybe you could use it in your application.

In ZK framework you need to use Progressmeter component. In your example.zul you need to add the following code :

 <progressmeter id="uploadProgress" value="0" width="300px" />

And in your project class you need to update value of this component.

    public class ProgressmeterController extends SelectorComposer<Hlayout> {
    @Wire
    private Progressmeter uploadProgress;

    @Wire
    private Timer timer;

    @Listen("onTimer = #timer")
    public void fetchingSimulatorTimer() {
        //calculate completed percent
        uploadProgress.setValue(percent);
        }
}
