Send XML string to servlet in a hidden variable via http POST not working.

I am trying to send xml file string to server side via a hidden variable buts its breaking up.. If i comment that line it works fine.. Can you let me know what i am missing? I tried hidden, textarea, url.encode, safehtmlutils, Base64 encoding , just to get this value to server side, but it doesnt work... Any help will be greatly appreciated.

Thanks

String jsonResult = JSONUIHelper.toJson(result);
FormPanel form = new FormPanel();

_log.logMsg(BsLogLvl.DEBUG, "form.start;" + GWT.getModuleBaseURL());
form.setEncoding(FormPanel.ENCODING_MULTIPART);
form.setMethod(FormPanel.METHOD_POST);
form.setAction(GWT.getModuleBaseURL() + "dnldSvc");
Hidden hiddenFileName = new Hidden("fileName", "Atty.zip");
TextArea hiddenJSON = new TextArea();
hiddenJSON.setName("jsonData");
hiddenJSON.setValue(URL.encode(jsonResult));
hiddenJSON.setEnabled(false);
// SafeHTMLUtils.
form.add(hiddenFileName);
form.add(hiddenJSON);
form.submit();
_log.logMsg(BsLogLvl.DEBUG, "after submit();");

form.addSubmitCompleteHandler(new FormPanel.SubmitCompleteHandler() {

public void onSubmitComplete(SubmitCompleteEvent event) {

_log.logMsg(BsLogLvl.DEBUG, "after onSubmitComplete;" + event);
}
});
