I want to have a link that when hit will download a csv file. I would
prefer to use a Page or a component that I can use the @SpringBean
notation on so the csv file data can be retrieved via my service layer
beans.
I can generate the file using a WebPage with the following in my
constructor for the page where sb is my StringBuilder holding the data.
WebResponse response = (WebResponse)
this.getResponse();
java.io.OutputStream cout =
response.getOutputStream();
try {
cout.write(sb.toString().getBytes());
cout.flush();
cout.close();
} catch (IOException e) {
// TODO Auto-generated
catch block
e.printStackTrace();
}
My page also overrides setHeaders to set the proper headers, ContentType
and Header specifying download and file name.
The problem with this is the following 2 errors are thrown:
011-07-13 17:58:23,910 ERROR org.apache.wicket.RequestCycle
RequestCycle:1529 - Markup of type 'html' for component

called for this response
Any ideas?
