Dear all,
For some reason, I have 2 dropdownchoice(year and month) , according to year
and month to decide the filename , then click button to download file.
for the ajaxsubmitLink, my code is below, now once the file is existed, that
mean after running: getRequestCycle().setRequestTarget(new
RedirectRequestTarget(url));
, there is one page to select the location and download the file, but after
that, the page stop, i mean i can not click the "uLink" again,
anyone can give me some suggestion?
thank you very much
AjaxSubmitLinkWithIndicator uLink = new
AjaxSubmitLinkWithIndicator("uLink", form) {
protected void onSubmit(AjaxRequestTarget target, Form form) {
System.out.println("on click
AjaxSubmitLinkWithIndicator...........");
System.out.println("dobPanel.getDob() :" +
dobPanel.getDob());
Calendar calendar = Calendar.getInstance();
calendar.setTime(dobPanel.getDob());
System.out.println("calendar.get(Calendar.YEAR) :" +
calendar.get(Calendar.YEAR));
System.out.println("calendar.get(Calendar.MONTH) :" +
calendar.get(Calendar.MONTH));
final String fn = orgDetailName + "_m_" +
calendar.get(Calendar.YEAR) + "_" + (calendar.get(Calendar.MONTH) + 1) +
".csv";
logger.error("fn:" + fn);
path = wholePath + calendar.get(Calendar.YEAR);
logger.error("path.trim() + '/' + fn):" + path.trim() + "/"
+ fn);
final File f1 = new File(path.trim() + "/" + fn);
if (f1.exists()) {
ResourceReference rf = new ResourceReference("") {
@Override
protected WebResource newResource() {
return new WebResource() {
@Override
public IResourceStream getResourceStream() {
// throw new
UnsupportedOperationException("Not supported yet.");
String endWithString =
fn.substring(fn.indexOf(".") + 1, fn.length());
String contentType =
FileTypeMapping.getInstance().get(endWithString);
if (fn.endsWith("xlsx")) {
FileUtility fileUtil = new
FileUtility();
byte[] bytes =
fileUtil.getBytesFromFile(f1);
return new
ByteArrayResourceStream(bytes, contentType);
} else if (fn.endsWith("csv")) {
CharSequence maps =
generateCsvFile(f1);
return new
StringResourceStream(maps, contentType);
} else {
return null;
}
}
@Override
protected void setHeaders(WebResponse
response) {
super.setHeaders(response);
response.setAttachmentHeader(fn);
}
};
}
;
};
String url =
getRequestCycle().get().urlFor(rf).toString();
logger.error("url:" + url);
getRequestCycle().setRequestTarget(new
RedirectRequestTarget(url));
} else {
cfp.info("There is no file for the day.");
cfp.setVisible(true);
target.addComponent(cfp);
}
}
};
