Re: AJAX update and file download on Wicket 1.5
So I modified my AjaxFileDownload init method to eliminate the abstraction of
getResourceStream. Code as follows:
AjaxFileDownload.java... Similar to AJAXDownload described in the Wiki
https://cwiki.apache.org/WICKET/ajax-update-and-file-download-in-one-blow.html
except for the following modifications:
/**
* Call this method to initiate the download.
*/
public void initiate(AjaxRequestTarget target, String fileName,
InputStream is) {
this.fileName = fileName;
this.is = is;
String url = getCallbackUrl().toString();
if (addAntiCache) {
url = url + (url.contains(?) ? : ?);
url = url + antiCache= + System.currentTimeMillis();
}
// the timeout is needed to let Wicket release the channel
target.appendJavaScript(setTimeout(\window.location.href=' + url
+ '\, 100););
}
/**
* Hook method providing the actual resource stream.
*/
protected IResourceStream getResourceStream() {
return new AbstractResourceStreamWriter() {
public void write(Response output) {
WebResponse response = (WebResponse)output;
byte[] buffer = new byte[256];
try {
int read;
while((read = is.read(buffer)) != -1) {
response.write(buffer, 0, read);
response.flush();
}
response.close();
} catch (Exception e) {
response.write(e.toString().getBytes());
response.close();
}
getComponent().getRequestCycle().setResponsePage(MCEVToolPage.class);
}
};
}
Implementation:
final AjaxFileDownload fileDownload = new AjaxFileDownload();
AjaxLink fileDownloadLink = new AjaxLink(fileDownloadLink) {
@Override
public void onClick(AjaxRequestTarget target) {
StringBuilder fileNameBuilder = new StringBuilder();
//Build filename
.
.
StringBuilder dataBuilder = new StringBuilder();
//builder data to be included in the file
..
..
fileDownload.initiate(target, fileNameBuilder.toString(), new
ByteArrayInputStream(dataBuilder.toString().getBytes()));
}
}
fileDownloadLink.add(fileDownload);
add(fileDownloadLink);
Now you can create a single instance of AjaxFileDownload and include that in
your Application file and request when ever needed.

Re: Label not updating on AJaxButton submit
Martin,
Would you be kind enough to give an example?
I tried the following:
ajaxSimpleUploadForm.add(new AjaxButton(uploadVideoSubmit) {
@Override
protected void onSubmit(AjaxRequestTarget target, Form? form)
{
AbstractResourceStreamWriter writer = new
AbstractResourceStreamWriter() {
@Override
public void write(Response output) {
for(FileUpload upload : uploads) {
System.out.println(new Date() + : + Start
Reading);
try {
long size = upload.getSize();
BufferedReader fileReader = new
BufferedReader(new InputStreamReader(upload.getInputStream()));
ByteArrayOutputStream os = new
ByteArrayOutputStream();
int i;
int counter = 0;
while((i = fileReader.read()) != -1) {
counter ++;
os.write(i);
if(counter == 100) {
long osSize = os.size();
int p = Float.valueOf((100 * osSize)
/ size).intValue();
counter = 0;
if(p percent) {
percent = p;
p = 0;
}
}
}
os.flush();
os.close();
System.out.println(new Date() + : + File
read successfully);
} catch(IOException ie) {
VideoUploadPanel.this.error(There was a
problem uploading the file);
}
}
}
};
getRequestCycle().scheduleRequestHandlerAfterCurrent(
new ResourceStreamRequestHandler(writer);
...
}
The progress bar still does't get updated. Here is the response.. Note the
delay of 8 seconds marked in bold? Thats when the file is getting uploaded.

Any help / example would really be a life saver. I couldnt find much example
online on IResource and AjaxChannel

Hi,
I think the Ajax calls are serialized.
The page instance can be used by a single request at any time.
So you submit the form and this request acquires the lock on the page.
AjaxSelfTimerUpdatingBehavior cannot use the page until the first
request unlock it.
Additionally the Ajax calls are serialized at the client side
(JavaScript). See AjaxChannel class for more information about this.
To be able to do what you want I suggest to use IResource to upload
to. This way there wont be lock on the server side and with
AjaxChannels with different names at the client side you will solve
both problems.

I decided to go with a simple outer div and internal div while update
the internal div percentage to show the progress. Finally i added a
Label
inside the internal div to show the status...
/div style=border: 1px solid #5d4617; padding: 3px; background-color:

div style=width:0%; background-color: #FF9900;
align=right wicket:id=customProgressLoading.../div
/div
/div/
Finally i added AjaxSelfUpdatingTimerBehavior to the internal div to
fetch
the progress and label every 2 seconds.
When i click on submit button.. the label is not update while the form is
being submitted. it shows the final progress i.e. 100% and processing
completed after file is uploaded.
I am using AjaxButton

http://apache-wicket.1842946.n4.nabble.com/file/n3523546/Screen_shot_2011-05-14_at_9.55.31_PM.png I need to create a table like the attached image. I am not seasoned in wicket. I am not able to analyze where to start. I was able to create a DataTable but could not figure out how to get it started.
