Hello guys!
In a page, I have a button. The button starts a thread, just like this, but I
get the exception in the bottom. Here is some code:
@Override
protected void onSubmit(final AjaxRequestTarget target, Form<?> form) {
final FileUpload fileUpload = fileUploadField.getFileUpload();
if (fileUpload != null) {
final PhonebookImporter importer = new
PhonebookImporter(((AppSession) Session.get()).getManager());
logger.debug("User " + context.getEmail()
+ " uploaded an import file - " + fileUpload.getClientFileName());
byte[] bytes = fileUpload.getBytes();
String uploadFolder;
try {
uploadFolder = System.getenv("CATALINA_HOME")
+ props.get("uploadFolder");
} catch (SMSOfficeException e1) {
logger.error("Could not resolve property!", e1);
uploadFolder =
"/home/project/services/apache-tomcat-6.0.20/webapps/ROOT/temp/";
}
User currentUser = ((AppSession) Session.get()).getContext()
.getUser();
final File uploaded = new File(uploadFolder
+ String.valueOf(currentUser.getId()) + "/" +
fileUpload.getClientFileName());
uploaded.getParentFile().mkdirs();
try {
FileOutputStream fos = new FileOutputStream(uploaded, false);
fos.write(bytes);
fos.close();
logger.info("File written on " + uploaded.getAbsolutePath());
} catch (IOException e) {
logger.error("I/O Exception occurred!", e);
return;
}
final ImportListener listener = new ImportListener() {
public void info(String object, ImportMessage type) {
textModel.append(getString(type.toString()) + object + "\n");
}
};
importer.setUser(((AppSession) Session.get()).getContext().getUser());
importer.setDomain(((AppSession) Session.get()).getContext()
.getDomain());
importer.addImportListener(listener);
new Thread(new Runnable() {
public void run() {
try {
boolean flag = importer.importContacts(uploaded, null);
if (flag) {
BulkImport.this.info(BulkImport.this.getString("imported"));
logger.debug("User " + context.getEmail()
+ " managed to import the contacts!");
} else {
BulkImport.this.error(BulkImport.this.getString("enc_error"));
logger.error("User " + context.getEmail()
+ " did NOT manage to import the contacts!");
}
} catch (Exception e) {
logger.error("User " + context.getEmail()
+ " did NOT manage to import the contacts!", e);
BulkImport.this.error(BulkImport.this.getString("not_imported"));
}
importer.removeImportListener(listener);
target.addComponent(feed);
}
}).start();
} else {
BulkImport.this.error(getString("no_uploaded_file"));
}
}
And the exception:
