In my project, I have a button that lets the user download the contents
of a datatable in a form that MSExcel can interpret:
Button button = new Button("excelExport") {
protected void onSubmit() {
getRequestCycle().setRequestTarget(new
ComponentRequestTarget(dataTable));
WebResponse wr=(WebResponse)getResponse();
wr.setContentType( "excel/ms-excel; name=myFilename.xls" );
wr.setHeader("content-disposition",
"attachment;filename=myFilename.xls");
}
};
Suppose I want the button to download a text file containing some
arbitrary text (not necessarily the contents of a DataTable). Would I
do something like this?
Button button = new Button("textfileExport") {
protected void onSubmit() {
StringResponse response = new StringResponse();
response.write(
"Whatever I want contained in the output text file..."
);
getRequestCycle().setResponse(response);
WebResponse wr=(WebResponse)getResponse();
wr.setContentType( "text/plain; name=myFilename.txt" );
wr.setHeader("content-disposition",
"attachment;filename=myFilename.txt");
}
};
If not, what is the proper approach?
