Re: how does DownloadLink lock the page?
Hi Lucio, only the *page instance* containing the DownloadLink is locked by the download. Each user gets his own page instances, and these do not affect each other.

Re: Input Stream DownloadLink
Hi, Thanks for sharing your component with us! In the "about" section you use LoadableDetachableModel that returns InputStream. For single use this would work fine, but if you try to use this model second time in the same request then it may fail depending on the type of the InputStream because you may need to reset it. I cannot imagine now a use case where you will need to use it second time in the same request but I also see no reason to use LDM. Using AbstractReadOnlyModel looks better to me. Apart from that I think you can use "new ResourceLink(String, IResource)" for the same kind of tasks. E.g. with ByteArrayResource that either accepts its byte[] as constructor parameter or loads it dynamically by overriding #getData(). Happy New Year!

Re: Input Stream DownloadLink
Hi Martin, I found it very useful and really appreciate you contribution. I think it is definitely worth of effort, if something very similar does not already exist in wicket distribution. In that case, it would be great source of inspiration for new pull-request into wicket. Simple, short and clean description.

Input Stream DownloadLink
Hello all, I just published a small version of a download link which enables you to serve any data coming from an InputStream for download. https://github.com/pingunaut/wicket-stream-download-example I used that one in multiple projects now, so I thought it could be interesting for other people too. Just wanted to hear, if there any need for this one out there before spending more effort for docs and error handling.

Re: DownloadLink in a separate thread?
Hi, Yes. Using ResourceLink will produce a url to IResource and thus avoid locking the page instance.

DownloadLink in a separate thread?
Just checking to see if I'm doing this right: When users click on a "download" link on my Wicket application, I want to be zip all the files in a directory on the fly and return the user one big *.zip file. This is working as expected, but since the number of and size of files can be quite big, this can take a while to process. Is "DownloadLink" the right wicket component to implement this? Does it make sense to run this in a separate thread?

Re: DownloadLink and ProgressBar
Hi,
I haven't seen a web application that shows progress bar for download.
The browser itself shows such information - Google Chrome in the
bottom-left corner, Firefox in its download window/manager.

Point 3) won't work if the file download is from a resource linked to the
page. And it is thru DownloadLink.
In this case the ajax timer won't be able to reach the page at all.
The app should use a mounted/shared resource.
see wicket-extensions' UploadProgressBar and/or follow the progress of
https://github.com/l0rdn1kk0n/wicket-bootstrap/issues/262 for example. Both
are related to *upload*, not download.

Re: DownloadLink and ProgressBar
Create a class that implements Runnable. Find how to launch a runnable
(e.g. using a thread pool). Keep a reference to this runnable and use some
property of it to track progress. Use an AJAX timer to pol for this value.

Re: DownloadLink and ProgressBar
Dear Ernesto
Thank you very much for your help. Your comments were very helpful.
I solve the problem as you suggested with little modification
1. follow the reference you mention [1]
2. add AjaxLink that will generate a file
add(new AjaxLink("download")
{
@Override
public void onClick(final AjaxRequestTarget target)
{
bar.start(target);
new Thread()
{
public void run()
{
generateFile
}.
3. add a progressbar (from wicketstuff) and on its onFinsh method, trigger
the file download
Progress = new ProgressBar("progress", new ProgressionModel()
{
protected Progression getProgression()
{
return new Progression(progress);
}
})
{
protected void onFinished(AjaxRequestTarget target)
{
download.initiate(target, fileName);
}
progress.add(download)
add(progress)
My only problem now is I have to guess the progress of file genaration , to
be dispalyed on the progress bar
thank you very much

Re: DownloadLink and ProgressBar
Thank you Ernesto for your prompt response. 1. is okay. Then for 2. I suppose I start the thread from the onclick method of the ajax link. Can you explain a bit how to start the file genaration with a thread? and for 3. how to pol the server for the progress?

Re: DownloadLink and ProgressBar
Hi,
1-Replace the download link by an AJAX link.
2-Launch file generation on a background thread. Pass a class to this
thread that serves as context fro passing information from generating
thread with web threads (keeping a reference to thisi context on the page).
3-Make a progress panel visible + an AJAX timer that pols the server for
progress.
4-Once file is generated replace progress panel with a download link (or
use trick in [1] to trigger file dowmload)

DownloadLink and ProgressBar
Hi All,
I have a wicket DownloadLink where I generate file dynamically and download
it. It works.
The process of dynamic File generation might take some time and like to show
ProgressBar which show how much the generation has progressed. How Can I do
that.
I am using wicket 1.5.8
Thank you very much.
add(new DownloadLink("export", new LoadableDetachableModel()
{
private static final long serialVersionUID =
840863954694163375L;
@Override
protected File load()
{
File exportTempDir = getGeneratedFile();
}
}

Re: DownloadLink
Hi, See the code in DownloadLink. It just schedules an additional request handler. You can do the same in your #onSubmit() method.

DownloadLink
Hi; Is it possible to trigger form submit before DownloadLink execution. We need to get some values from the form in order to process pdf. Any suggestions ? Thanks.
Re: DownloadLink
Ok, so this is my code (works, irrelevant striped):
public class PageIndex extends PageBase{
...
...
...
final Integer fileDbIdTmp = (Integer) oneResult.get("fileId");
final byte[] bytes = new String("content of the created file for
download").getBytes();
ResourceLink downloadLink = new ResourceLink("downloadLink", new
AbstractResource()
{
private Integer fileDbId = fileDbIdTmp;
@Override
protected ResourceResponse newResourceResponse(Attributes attributes)
{
ResourceResponse r = new ResourceResponse();
r.setFileName("mypdf.pdf");
r.setContentType("application/pdf");
r.setContentDisposition(ContentDisposition.ATTACHMENT);
r.setContentLength(bytes.length);
r.setWriteCallback(new WriteCallback()
{
@Override
public void writeData(Attributes attributes)
{
//here, the data for .pdf should be loaded on-demand from DB with
some appropriate model...
MyDAOObject myDBData = new MyDAOObject(fileDbIdTmp);//just pseudo-code
attributes.getResponse().write(myDBData.loadData());
}
});
return r;
}
});
panelEvent.add(downloadLink);
this.add(panelEvent);
...
...
...
}
Now I would like construct LoadableDetachableModel (using this model for
loading strings for same panels) or something similar
so I can construct data from DB based on some id (I have DB id of the element -
in this case .pdf file stored in DB).
After consult doc:
http://wicket.apache.org/apidocs/1.5/org/apache/wicket/markup/html/link/ResourceLink.html
I can't see where to put model, or where to hook model into ResourceLink.
In my code in writeData() there is line for loading data but I think this is
ugly solution...
Any help appreciated.

Re: DownloadLink
Dan, thank you for links and points.
The true is that I have data in database so I would like streaming them. Is the
right
way put them in temp file first and then send it into browser with DownloadLink?
After some googling I noticed that ResourceLink should be like DownloadLink but
for me
better - it's for streamed data. But can't find any example for wicket 1.5 :-(

Michael, check out the DownloadLink example here:

Also check out the code for DownloadLink itself, and you'll see
1. Your IModel must return a File, but yours returns bytes.
2. The download is initiated in DownloadLink#onClick, which you have
blocked with your subclass.
Hope that helps,

Re: How to avoid keeping files on the server with DownloadLink
Never mind, I found out -- override "protected void setHeaders(WebResponse response) " in ByteArrayResource. OK, thanks, it's almost done, but there's still one issue. It's working fine, but when I click the link the FIRST time, I get the Open/Save As and when I click Open, Excel opens MyApp[1].xls. Then when I click the SECOND time, I also get Open/Save As, and when I click Open this time, Excel gives me this: "MyApp[1].xls is locked for editing. Open Read-Only or Notify" This never happened with the DownloadLink. With the DownloadLink, every click was a valid Excel file open. Now, it looks like the local isn't being released for some reason. I have to either cancel or click Read-Only, and then on the next open it's fine again. Very strange... -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/How-to-avoid-keeping-files-on-the-server-with-DownloadLink-tp3750767p3751200.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: How to avoid keeping files on the server with DownloadLink
Thanks,
I was able to convert a DownloadLink to a ResourceLink (backed by a byte[]),
BUT that changed the behavior of the link.
Previously, all clicks on the DownloadLink would result in a Open / Save As
dialog box. This is what we want. The file type is MS Excel, and it was
offering to open or save the file.
Now, with the ResourceLink, it's a little different:
1) The Excel file opens immediately inside of IE, no prompts
2) If, from another browser/session, the link is clicked by another user,
there's an Excel error, "A document with the name 'localhost' is already
open"
The code:
ByteArrayResource bar = new ByteArrayResource("application/vnd.ms-excel",
generateExcelBytes()); //returns byte[]
ResourceLink exportLink = new ResourceLink("exportLink", bar);
add(exportLink);
Previously, with the DownloadLink, the code was:
DownloadLink exportLink = new DownloadLink("exportLink",
generateExcelFile()); //returns File
add(exportLink);

How to avoid keeping files on the server with DownloadLink
Just one more question, Is it possible to do a resource download from memory, *not* from a file on the server? I currently have a DownloadLink pointing to a generated file. That is fine, but we have multiple files getting generated and residing on the server that don't get cleaned up. We are interested in whether it's possible to do a download purely from memory. BTW, I am aware that DownloadLink has a method called "setDeleteAfterDownload(true)", but that's not what we want. If we have that, then the 2nd time the user clicks the same link, there's an error. We want correct file download each and every time the link is clicked, we just don't want server files getting created.

Re: Force DownloadLink
I've tried the above options but they didn't work.
what I have now is
exportEnv.setWindowClosedCallback(new ModalWindow.WindowClosedCallback()
{
public void onClose(AjaxRequestTarget target)
{
final File exportFile= getFile();
IResourceStream resourceStream = new FileResourceStream(
new
org.apache.wicket.util.file.File(exportFile));
getRequestCycle().setRequestTarget(
new
ResourceStreamRequestTarget(resourceStream) {
public String
getFileName() {
return
exportFile.getName();
}
});
}
});
the code is being processed but the file is not being exported.

alternative fine name: see onClick() method to see how it is used. Can
you try following panel?
import java.io.File;
import org.apache.wicket.markup.html.basic.Label;
import org.apache.wicket.markup.html.link.DownloadLink;
import org.apache.wicket.markup.html.panel.Panel;
public class DownLoadLinkPanel extends Panel {
private static final long serialVersionUID = 1L;
/**
* @param id
*/
public DownLoadLinkPanel(String id) {
super(id);
DownloadLink dl = new DownloadLink( "download", new File(
"wat-application/images/addmore.jpg" ), "AddMore.jpg" );
add(dl);
dl.add(new Label("text", "Example DownloadLink"));
}
}
DownLoadLinkPanel.html
---
and then
return new DownLoadLinkPanel(componentId);

Re: LinkTree and DownloadLink
I think the problem is in this: DownloadLink dl = new DownloadLink( id, new
File( "wat-application/images/addmore.jpg" ), "Example DownloadLink" );
This does not produce any output.

Re: LinkTree and DownloadLink
Not sure but I think if you put Link on a you will have a
generated markup which might not be visible.
Why don't you use a panel like following?

Do you know why if I add DownloadLink directly without the panel, its
invisible?

Re: LinkTree and DownloadLink
Your MyPanel extends Form and Form should be applied to tag not
tag.

LinkTree and DownloadLink
Hi,
I am trying to extend newNodeComponent on a LinkTree to make nodes
DownLoadLink.
tree = new LinkTree("tree", createTreeModel()){
private static final long serialVersionUID = 1L;
@Override
protected Component newNodeComponent( String id, IModel model )
{
return new LinkIconPanel( id, model, this ) {
private static final long serialVersionUID = 1L;
@Override
protected Component newContentComponent( String
componentId, BaseTree tree, IModel model ) {
Object obj = ( ( DefaultMutableTreeNode
)model.getObject() ).getUserObject();
if( !obj.equals("1:subtree...,
2:subtree..., 3:subtree...") ) {
LOGGER.debug("link");
return new MyPanel(componentId);
}
return new Label( componentId,
model.getObject().toString() );
}
};
}
};
form.add(tree);
tree.getTreeState().collapseAll();
public class MyPanel extends Form {
private static final long serialVersionUID = 1L;
MyPanel(String id) {
super(id);
DownloadLink dl = new DownloadLink( id, new File(
"wat-application/images/addmore.jpg" ), "Example DownloadLink" );
add(dl);
}
}
I copied the example from:
http://www.wicket-library.com/wicket-examples/ajax/tree/simple.0
But i get the following error:
WicketMessage: Component content must be applied to a tag of type 'form',
not '' (line 0,
column 0)
, index = 8, current = '' (line 19, column 144)]

RE: DownloadLink problem
Oh my God!!! The problem was that the button that is supposed to do the export
was of type submit and it reloads the page, instead of refreshing components. I
changed to type=button and everything's fine...
As people say - there is no patch for human stupidity...
Thank you all for the help!
Best,
Martin

Thanks Ernesto!
But I want to have the link invisible on startup (because the file's empty). So
I have this: (doesn't work, but has to)
exportedFileLink = new DownloadLink("exported_file_link", new
LoadableDetachableModel() {
private static final long serialVersionUID = 1L;
@Override
protected File load() {
return exportedFile;
}
}, PhonebookExporter.OUTPUT_FILE_NAME) {
private static final long serialVersionUID = 1L;
@Override
public boolean isVisible() {
return exportedFile != null;
}
};
final WebMarkupContainer exportedFileLinkHolder = new
WebMarkupContainer("link_holder");
exportedFileLinkHolder.setOutputMarkupId(true);
exportedFileLinkHolder.add(exportedFileLink);
rightForm.add(exportedFileLinkHolder);
rightForm.add(new AjaxButton("export_button") {
private static final long serialVersionUID = 1L;
@Override
protected void onSubmit(AjaxRequestTarget target, Form form) {
PhonebookExporter exporter = getExporter();
exportedFile = exporter.export(uploadFolder);
if (exportedFile == null) {
error(getString("not_exported"));
} else {
info(getString("exported"));
}
target.addComponent(exportedFileLinkHolder);
target.addComponent(feed);
}
});
I really start to get pissed off by this one!!! g

DownloadLink problem
Hi, guys!
I experience some DownloadLink problem - I have these fields:
File linkModel;
DownloadLink theLink = new DownloadLink("link_id", new Model(linkModel));
theLink.setOutputMarkupId(true);
After another button click I have the linkModel field pointing to real file on
the file system. And then I say:
target.addComponent(theLink);
the link name is still invisible, and when I click on the small clickable area,
Wicket comes up with:
WicketMessage: Method onLinkClicked of interface
org.apache.wicket.markup.html.link.ILinkListener targeted at component
[MarkupContainer [Component id = exported_file_link]] threw an exception
Root cause:
java.lang.IllegalStateException:
org.apache.wicket.markup.html.link.DownloadLink failed to retrieve a File
object from model
at
org.apache.wicket.markup.html.link.DownloadLink.onClick(DownloadLink.java:141)
at org.apache.wicket.markup.html.link.Link.onLinkClicked(Link.java:224)
at java.lang.reflect.Method.invoke(Method.java:597)
I thought I've made everything perfect, but it seems that I haven't.
Any help is appreciated!
Best regards,
Martin
Re: DownloadLink and Resource
1.3.x branch is no longer actively developed. you can add your wishes
to the 1.4.x branch.
downloadlink is a small class that does nothing special, you can copy
paste it into your own and customize if the core one does not meet
your needs.

DownloadLink and Resource
Hi,
I have two separate questions/wishes:
we use Wicket 1.3.6
DownloadLink - can we add a getter for fileName (I can open an issue in JIRA
if it's necessary).
Resource:
onResourceRequested is final so I can't override the
ResourceStreamRequestTarget in the line cycle.setRequestTarget(new
ResourceStreamRequestTarget(resourceStream));
Is it possible to add something like:
protected ResourceStreamRequestTarget
getResourceStreamRequestTarget(IResourceStream resourceStream) {
return new ResourceStreamRequestTarget(resourceStream);
}
so we could override the ResourceStreamRequestTarget that is used?
thanks,

RE: DownloadLink
But how would this prevent the PageMap from getting blocked?
Would it be possible to somehow span a request that isn't tied to the same
session i.e get the same behavior of a "non-wicket servlet" but still have it
live inside the wicket application?

A shared resource can be added like this:

Instead of webResource, you can have another implementation of Resource

Help,DownloadLink, when file is not existed, not error message
Dear all,
I am doing downloadLink , when the file is existed, it is ok to download it,
but when the file is not existed, no any error message "No file exist!" to
popup!
According to debug, i can see it already go to the line:
target.appendJavascript("alert('No file exist!')");
the codes is below,
any suggest?
thanks you for help.
File file = new File("C:/Documents and
Settings/cw/Desktop/Advertiser_csv/AdSmart/2008/B-ONE FLORIST (SHAW
TOWER)_m_2008_12.csv");
form.add( new CustomDownloadLink("donld", file));

Re: DownloadLink, BIRT report
Hi,
I already wrote to you in private and didn't noticed you were also
posting to the list... Here is the transcript of my last two private e-mails
.
You have to download the BIRT runtime from
http://download.eclipse.org/birt/downloads/
This is what you have to deploy with your WEB application. The
runtime is like an eclipse (an equinox OSGi runtime) but stripped of
all the GUI thing and containing just the minimal functionality to
execute BIRT reports: the designer but without the design part. That way
the footprint is small as you have to distribute it with your WEB
application. The code I showed you on the list was to instantiate this
runtime from within your WEB application. Then you use that runtime to
build your reports. In my experience, it is better if this runtime is
the same version as the designer you used to build your reports
(otherwise you might find unpleasant surprises).

This error is because you have to copy some of the jar files on
runtime/plugins to your classpath (and/or the WEB-INF/lib folder
depending on how you setup your project). I have the following:
/WEB-INF/lib/birt-chartengineapi-2.3.jar
/WEB-INF/lib/birt-com.ibm.icu_3.8.1.v20080530.jar
/WEB-INF/lib/birt-coreapi-2.3.jar
/WEB-INF/lib/birt-crosstabcoreapi-2.3.jar
/WEB-INF/lib/birt-dataadapterapi-2.3.jar
/WEB-INF/lib/birt-dataaggregationapi-2.3.jar
/WEB-INF/lib/birt-dteapi-2.3.jar
/WEB-INF/lib/birt-emitter.prototype.excel_2.3.0.v20080606.jar
/WEB-INF/lib/birt-engineapi-2.3.jar
/WEB-INF/lib/birt-flute-2.3.jar
/WEB-INF/lib/birt-js-2.3.jar
/WEB-INF/lib/birt-modelapi-2.3.jar
/WEB-INF/lib/birt-modelodaapi-2.3.jar
/WEB-INF/lib/birt-odadesignapi-2.3.jar
/WEB-INF/lib/birt-org.apache. commons.codec_1.3.0.v20080530-1600.jar
/WEB-INF/lib/birt-org.eclipse.birt.report.engine.dataextraction_2.3.0.v20080611.jar
/WEB-INF/lib/birt-org.eclipse.emf.common_2.4.0.v200806091234.jar
/WEB-INF/lib/birt-org.eclipse.emf.ecore_2.4.0.v200806091234.jar
/WEB-INF/lib/birt-org.eclipse.emf.ecore.xmi_2.4.0.v200806091234.jar
/WEB-INF/lib/birt-org.w3c.css.sac_1.3.0.v200805290154.jar
/WEB-INF/lib/birt-scriptapi-2.3.jar
But maybe I'm missing in this list some related jars... Some of the
jars on previous list have shortened names, not the names they have on
the runtime/plugins folder, but I guess you will have no problems in
finding them. If you don't add these jars then your IDE (eclipse?) won't
be able to compile the "Birt" class of my first e-mail. Once the class
compiles then try something simple (like building a hello world report).
I forgot to mention this on my previous e-mails...

RE: DownloadLink, BIRT report
You should not need to copy anything to the eclipse\plugins since you
downloaded Eclipse with Birt support.
You will need to add the birt runtime jars into your eclipse project. They can
be found in \ReportEngine\lib
There are a couple ways to do this in eclipse:
1. Go to Build Path --> Configure Build Path --> Libraries. You can manually
add jars with the Add External Jars button. You need at least 2 of the birt
jars - engineapi.jar and coreapi.jar. You may need more depending on what
functions you are using within birt.
2. If you want Maven to handle this, then you will need to add the artifacts
manually to your local repository. The latest birt runtime 2.3.1 is not in a
central repository. I added all the jars that you see in the \lib directory; a
few where already there from the central repository. I then created a
birt-2.3.1 artifact with a pom.xml that has all of the jars as dependencies.
All I need to do then is add the birt-2.3.1 artifact to my project and all of
the birt jars are automatically added.
There may be other ways to do this too. I am new to Maven also. It took quite
a bit of research to get this far. Good luck!

I had started off by downloading the birt-all-in-one (came bundled with the

Created a maven project( wicket quickstart) , then designed the birt
rptdesign (all within the eclipse platform) I run it outside eclipse, (mvn

Now, I have downloaded the birt runtime engine, and copied files from the
birtrunttime\ReportEngine\plugins to the eclipse\plugins

Not sure what I should do for this.

Re: DownloadLink, BIRT report

This class initializes a singleton BIRT runtime and the
generateBirtReport(...) method can be used to read the report design from a
database and generate the corresponding report (PDF, excel, HTML). If you
filter out the logic that is specific to my use case you can easily build
your own machinery for building reports based on code given above.
As for the generation of the download link there should be plenty of

Re: DownloadLink, BIRT report
I don't know about BIRT, but I recently did an output to Excel page. You
link to it like any other page:
http://wicket.apache.org/";>
Auction Excel Download
That meta content in the head is more for documentation - it doesn't seem to
work without the final step below:
The Java code looks something like this to populate the table:
add(new DataView("rows", new MyDataProvider()) {
public void populateItem(final Item item) {
item.setModel(new CompoundPropertyModel(new
DetachableXYZModel(item.getModelObject(;
item.add(new Label("name"));
And the final magic makes it ask if you want to open it with excel:
@Override
protected void configureResponse() {
super.configureResponse();
getRequestCycle().getResponse().setContentType("application/x-msexcel");
}
That worked for me - hope it helps. (Also note you can output a mix of
literal data and formulas)
I use web app to collect data, then word merge templates for reports.

We've got problems with the DownloadLink, too. They work fine in Firefox
and Webkit-based browsers. However they do not work in IE6/7. IE complains
about the URL, it might be the same message but I'm not in front of the
system right now to verify this.

do you know whether the request reaches your downloadlink? for example,
you could check it by using:
add(new DownloadLink("download", fileModel) {
@Override
public void onClick() {
System.out.println("onClick of download link called!");
try {
super.onClick();
System.out.println("super onClick was successful");
} catch (Throwable t) {
t.printStackTrace();
}
}
});
or you could debug it of course..

Hi,
I was trying to use DownloadLink but for some reason I couldn't make it
work.
I'm trying to insert the link in a grid, but when I test the application
and I click the link, an error page appears "The webPage cannot be found"
this url appears in the page
http:///?wicket:interface=:7:table:rows:1:cells:
2:cell:download::ILinkListener::
here Is the code where I create the link
public class ActionPanel extends Panel{
public ActionPanel(String id, IModel model){
super(id, model);
try {
File file = ((Document)model.getObject()).getOriginalFile();
IModel fileModel = new Model();
fileModel.setObject(file);
add(new DownloadLink("download",fileModel));
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}
I've debug the app and I saw that the file was loaded, and the link was
created without any problem. Can anyone tell me if need anything else to
make it works?
Thanks in advance
