Hi, guys, I am going to lunch. I think it's wise to use this time to just ask
before I doing a test, can anyone tell me that:
is these data, include file data, still avaiable in HttpServletRequst object?
Why, because out old EJB object extract these data from HttpServletRequst.
Thanks,
Jirong
The following is the "upload" example which enables you get these info from Form
bean.
=
public class UploadAction extends Action {
public ActionForward perform(ActionMapping mapping,
ActionFormform,
HttpServletRequest request,
HttpServletResponse
response) {
if (form instanceof UploadForm) {
UploadForm theForm = (UploadForm) form;
//retrieve the text data
String text = theForm.getTheText();
//retrieve the file representation
FormFile file = theForm.getTheFile();
//retrieve the file name
String fileName= file.getFileName();
//retrieve the content type
String contentType = file.getContentType();
//retrieve the file size
String size = (file.getFileSize() + " bytes");
String data = null;
try {
//retrieve the file data
data = new String(file.getFileData());
}
catch (FileNotFoundException fnfe) {
return null;
}
catch (IOException ioe) {
return null;
}
//place the data into the request for retrieval from display.jsp
request.setAttribute("text", text);
request.setAttribute("fileName", fileName);
request.setAttribute("contentType", contentType);
request.setAttribute("size", size);
request.setAttribute("data", data);
//destroy the temporary file created
file.destroy();
//return a forward to display.jsp
return mapping.findForward("display");
}
//this shouldn't happen in this example
return null;
}
