Using eclipse/tomcat, I have a single page wicket app with a single link for
downloading an excel sheet (*.xlsm, around 6MB) and it works, great.
However, when I plug the same piece of code in my main web application
(wicket + spring + hibernate + mysql), it throws
"java.io.IOException: ZIP entry size is too large". I am not able to figure
out the problem. I suspect it has something to do with springframe that I
use in my main web app.
Here is the exception
java.io.IOException: ZIP entry size is too large

Here is the code...
public class DownloadGeneratedExcelPage1 extends WebPage {
private static final long serialVersionUID = 1L;
public DownloadGeneratedExcelPage1() {
add(new Link<Void>("download") {
private static final long serialVersionUID = 1L;
@Override
public void onClick() {
final IResource resource = new
ByteArrayResource(
"application/vnd.ms-excel")
{
private static final long
serialVersionUID = 1L;
@Override
protected byte[] getData(Attributes
attributes) {
InputStream in =
DownloadGeneratedExcelPage1.class
.getResourceAsStream("/templates/excelTest.xlsm");
ByteArrayOutputStream os =
new ByteArrayOutputStream();
try {
XSSFWorkbook
workBook = new XSSFWorkbook(in);
workBook.write(os);
} catch (IOException ex) {
ex.printStackTrace();
}
return os.toByteArray();
}
@Override
protected void
setResponseHeaders(ResourceResponse data,
Attributes
attributes) {
SimpleDateFormat df = new
SimpleDateFormat(
"yyyy.MM.dd_HHmm");
data.setFileName("testFile_"
+
df.format(new Date()) + ".xlsm");
data.disableCaching();
super.setResponseHeaders(data, attributes);
}
};
IRequestHandler handler = new
ResourceRequestHandler(resource,
null);
getRequestCycle().scheduleRequestHandlerAfterCurrent(handler);
}
});
}
}
I would highly appreciate your feedback. Many thanks.
