What is wrong? I am not getting the problem where I am going to wrong .Thanks for the help in advanced.
回答1:
I think the issue is in the
String filePath = "D:\\uploadImage";
File destFilePath = new File(filePath);
you are declaring a direction as a file, but you need a filename to write to a specific file.
for example try:
String filePath = "D:\\uploadImage";
File destFilePath = new File(filePath+"\\uploadimage.jpg");
回答2:
The error
java.io.FileNotFoundException: D:\uploadImage (Access is denied)
is quite clear: the file is not found.
To quote from your code:
File destFilePath = new File(filePath);
if (!destFilePath.exists()) {
new File(filePath).mkdirs();
}
FileOutputStream fos = new FileOutputStream(destFilePath);
fos.write(buffer);
In your particular case you are initially creating a directory by calling File#mkdirs() and later trying write to the directory referenced by that File object. This is not legal.
You need to create a file and write to the file instead. For instance, you could use Java SE 7 Files#copy(...). See also How to save uploaded file in JSF.

Thanks brother , I got the answer. at line 1 and line 2 where I am going to wrong. I was not specify the image name (file name)
public void photoListener(FileUploadEvent event) throws Exception {
UploadedFile item = event.getUploadedFile();
String fileName = "";
FacesContext context = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession) context.getExternalContext().getSession(false);
String destPath = session.getServletContext().getRealPath("/");
// String destPath = str.substring(0, str.substring(0, str.lastIndexOf(File.separator))
// .lastIndexOf(File.separator) + 1);
String filePath = destPath + "/UserInfo/" + getNewUserVO().getName();
File destFilePath = new File(filePath);
if (!destFilePath.exists()) {
new File(filePath).mkdirs();
}
try {
InputStream stream = item.getInputStream();
long fSize = item.getSize();
int lastIndex = item.getName().lastIndexOf(".");
String fileExtension = item.getName().substring(lastIndex);
if (!fileExtension.equalsIgnoreCase(".jpg")) {
FacesContext.getCurrentInstance().addMessage(
"",
new FacesMessage(FacesMessage.SEVERITY_ERROR, errorMsgBundle.getString("NEWUSER_BEAN_001"),
null));
} else if (fSize > 102400) {
FacesContext.getCurrentInstance().addMessage(
"",
new FacesMessage(FacesMessage.SEVERITY_ERROR, errorMsgBundle.getString("NEWUSER_BEAN_002"),
null));
} else {
System.out.println("user name--" + getNewUserVO().getName());
fileName = getNewUserVO().getName() + fileExtension;
filePath = destFilePath + File.separator + fileName; // line 1
FileOutputStream fos = new FileOutputStream(filePath); // line 2
byte[] buffer = new byte[(int) fSize];
stream.read(buffer, 0, (int) fSize);
stream.close();
fos.write(buffer);
fos.close();
getNewUserVO().setPhotoPath(filePath);
}
} catch (FileNotFoundException e) {
FacesContext.getCurrentInstance().addMessage("",
new FacesMessage(FacesMessage.SEVERITY_ERROR, errorMsgBundle.getString("NEWUSER_BEAN_003"), null));
log.info(e.getMessage());
} catch (Exception e) {
FacesContext.getCurrentInstance().addMessage("",
new FacesMessage(FacesMessage.SEVERITY_ERROR, errorMsgBundle.getString("NEWUSER_BEAN_004"), null));
log.info(e.getMessage());
}
}
