I, too, am trying to have my application download MS Excel files. Until now,
mine have contained the content of a DataTable, using the code I received
from the mailing list three years ago:
Button button = new Button("excelExport") {
public void onSubmit() {
getRequestCycle().setRequestTarget(
new ComponentRequestTarget(dataTable)
);
WebResponse wr = (WebResponse)getResponse();
wr.setContentType( "excel/ms-excel; name="+getMSExcelFilename() );
wr.setHeader( "content-disposition",
"attachment;filename="+getMSExcelFilename() );
}
};
The file downloaded contains an HTML fragment that both MS Excel and MS Word
can interpret, if one opens the resulting file in those applications.
Now my users told me they would like the download to contain not just the
data, but the date of its creation. Is there an easy way to pre-pend an
arbitrary string to that HTML fragment? I don't really understand the
details of Wicket's page rendering process, and looking at the classes I've
been using there don't seem to be any obvious hooks.
stream = class AbstractResourceStreamWriter()
{
public void write(OutputStream output)
{
// do your writing
}
}
getRequestCycle().setRequestTarget(
new ResourceStreamRequestTarget( stream ).setFileName(
"file.xls" )
);
