-------------------------------------------------------------------
In the abstract class we provide the infrastructure to
In POST: Create a progress object and store it in the session context with a
unique id.
In GET: retrieve object and get the current progress
In our code we do the following as implementation:
public class ProcessService extends AbstractAsyncronService {
public RestResponse doGet() throws Exception {
// we use the class name and a request parameter to make id unique
setId(this.getClass().getCanonicalName()+name);
Object progress = getProgress();
return new TextResponse("{\"progress\":"+progress.toString()+" }",
"application/json");
}
public RestResponse doPost() throws Exception {
// we use the class name and a request parameter to make id unique
setId(this.getClass().getCanonicalName()+name);
// execute business logic in background
super.bidExecutor.execute(this);
// Answer the client, reporting we have done 2%
return new TextResponse("{\"progress\":2"}", "application/json");
}
// long running action that will be done in a seperate thread
public void run() {
// if we reach here we have done 5% progress
this.updateProgress(5);
//... do business logic and finish progress with
this.updateProgress(100);
}
Our client is based on jquery ui progress bar. Where we post the form
$.post('rest/ProcessService', {
name: input
}, function(data){
onSuccess(data);
}, "json");
and in the onSuccess we invoke a loop to get the status like
window.progressIntervalId = window.setInterval(function(){
//Getting current operation progress
$.get('rest/ProcessService', {
name: input
}, function(data){
//Updating progress
$("#progressbar").progressbar('value', data.progress);
//If operation is complete
if (data.progress == 100) {
//Clear timer
window.clearInterval(window.progressIntervalId);
}
});
}, 500);
If you see this useful I can add the class and an example to the cocoon-rest
module.

> REST and asynchronous server side operations

> Key: COCOON3-75
> URL: https://issues.apache.org/jira/browse/COCOON3-75
> Project: Cocoon 3
> Issue Type: New Feature
> Components: cocoon-rest
> Reporter: Thorsten Scherler
> Assignee: Thorsten Scherler
> Attachments: AbstractAsyncronService.java
>
>
> I am looking into implementing reporting server side operation progress with
> jQuery UI Progressbar with our REST framework.
> My basic idea as starting point is to use the GET to ask for the
> progress of the processing and POST to invoke the work which reports the
> progress.
