How to display download link with file name in wicket
Hi,
I have 2 issues for which I need guidance from you.
Issue 1:::
In my application I am trying to write a page where I am having one html
file with one wicket panel with id mapped to a table.
And in the java file I am creating columns with AbstractColumns. Then I am
populating the DataTable with id (which is specified in the html page),
columns (created using AbstractColumns), dataprovider (this feeds the row
data to the table), and rows per page.
Coming to the columns, except one column all other are Label. And do not see
any problem.
But when I want to have a DownloadLink for a file present on the server I am
facing issue. I want to have the fileName as the DownloadLink which is not
happening. (Just to remind I am not using separate wicket ids for each
field). I am passing id, File (file object present on the server) and
fileName (this is the name displayed on the popup when the link is clicked).
This results in the Id being displayed in the place of link field and when
this is clicked I am able to download the file.
I need help on how do I get the fileName as download link instead of id.
new AbstractColumn(new MessageModel(COLUMN_NAME)) {
@Override
public void populateItem(Item cellItem, String id, IModel rowModel) {
final MyClass myClass = (MyClass) rowModel.getObject();
final File fileDirectory = new File(filePath);
cellItem.add(new DownloadLink(id, new File(fileDirectory, csvFile),
myClass.getFile()));
}
}
Issue 2 :::
I tried on more approach. For the download link I declared a Label with id
and href for the link. We are able to get the link but when clicked it is
appending the ip of the server which I do not want. I could not find any way
to remove that IP. Following is the code snippet used in side the column:
cellItem.add(new Label(componentId, "<a onclick=\"window.open('" +
filePath + "', '_blank'); target=\"_blank\"
href=\"" + filePath + "\" > " + fileName + "
").setEscapeModelStrings(false));
Thanks

Hi,
You have to add a Panel to the CellItem.
The panel should contain a link (<a>)

Hi Martin,
I tried the approach suggested by you and its working as expected. The file
name is displayed in the filed, and when clicked the file download pop up is
displayed.
However the file name is displayed as a link, but as a plain text. Is there
any way out to make sure it is displayed as a link ?
Regards,
Karthik S Patawardhan

Hello Martin,
Your understanding on the Issue 1 is correct. I want to show the file name
as a label for the link ? And this link should lead me to file download when
clicked.
I will try the approach given by you. Thanks a ton for the swift response.
Really appreciate it.!
Best Regards,
Karthik S Patawardhan

This is not very clear to me.
Do you want to show the file name as a label for the link ?
If YES then do:
String fileName = myClass.getFile();
cellItem.add(new DownloadLink(id, new File(fileDirectory, csvFile),
fileName).setBody(Model.of(fileName)));
> new AbstractColumn(new MessageModel(COLUMN_NAME)) {

I think my answer for #1 should help you.
Please give more details and examples if I'm not answering your question.
