Wicket : FileUploadPage doesnt refresh the filepath - file-upload

Question

again, i got a problem with wicket. Im trying to upload data with my Class "FileUploadPanel", which is implemented on another Page "Class A":
Class A
...
/* uploadfields for Picture and Video */
ArrayList<String> picExt = new ArrayList<String>();
ArrayList<String> videoExt = new ArrayList<String>();
picExt.add("jpg");
videoExt.add("mp4");
final FileUploadPanel picUpload = new FileUploadPanel("picUpload", "C:\\", picExt);
final FileUploadPanel videoUpload = new FileUploadPanel("videoUpload", "C:\\", videoExt);
final Form form = new Form("form"){
protected void onSubmit() {
...
// Save the path of Video and Picture into Database
table.setVideo(videoUpload.getFilepath());
table.setPicture(picUpload.getFilepath());
...
}
...
Class FileUploadPanel
public class FileUploadPanel extends Panel {
private static final long serialVersionUID = -2059476447949908649L;
private FileUploadField fileUpload;
private String UPLOAD_FOLDER = "C:\\";
private String filepath = "";
private List<String> fileExtensions;
/**
* Constructor of this Class
* #param id the wicket-id
* #param uploadFolder the folder, in which the File will be uploaded
* #param fileExtensions List of Strings
*/
public FileUploadPanel(String id, String uploadFolder, List<String> fileExtensions) {
super(id);
this.UPLOAD_FOLDER = uploadFolder;
this.fileExtensions = fileExtensions;
add(fileUpload = new FileUploadField("fileUpload"));
}
#Override
public void onComponentTag(ComponentTag tag){
// If no file is selected on startup
if(fileUpload.getFileUpload() == null){
return;
}
final FileUpload uploadedFile = fileUpload.getFileUpload();
if (uploadedFile != null) {
// write to a new file,
File newFile = new File(UPLOAD_FOLDER
+ uploadedFile.getClientFileName());
filepath = UPLOAD_FOLDER + uploadedFile.getClientFileName();
// if file in upload-folder already exists -> delete it
if (newFile.exists()) {
newFile.delete();
}
try {
newFile.createNewFile();
uploadedFile.writeTo(newFile);
info("saved file: " + uploadedFile.getClientFileName());
} catch (Exception e) {
throw new IllegalStateException("Error");
}
}
}
public String getFilepath() {
return filepath;
}
}
Well, if i use the submit-Button on my "Class A", the Pic and Video get saved on C:\, which is quite good so far. I thought i finally get along with wicket, but i cheered too soon...
Problem: The correct path is not saved in the Database, which is handled in the Form of "Class A"
I really dont get it, because the onComponentTag(...) of my FileUploadPanel must be executed when using the submit-button. Thats because i added some validations like "picture must be a JPG or wont be saved" in onComponentTag(...) - and that worked. So im sure, the onComponentTag(...) is executed when the Submit-Button of the Form is used, which also means the filepath should be up-to-date.
What is it im doin wrong this time?
Thank in Advance!

You are using
File newFile = new File(UPLOAD_FOLDER +
uploadedFile.getClientFileName());
this code to create a new File.
Instead of it you can try this one :
File file = new File(UPLOAD_FOLDER ,
uploadedFile.getClientFileName());
And then get the absolute path and save it:
newFile.getAbsolutePath();
