I have to upload and download a file using FTP server but I am facing issues in it. Have gone though many solutions but nothing seems to be working.
I am using secureftp-test.com as the testing FTP server.
Below is the code for uploading where in I am using FTPClient storeFile method but it doesn't seems to work.
public static void main(String[] args) {
String server = "ftp.secureftp-test.com";
int port = 21;
String user = "test";
String pass = "test";
FTPClient ftpClient = new FTPClient();
try {
ftpClient.connect(server, port);
boolean login = ftpClient.login(user, pass);
System.out.println("login " + login);
ftpClient.setFileTransferMode(FTP.BINARY_FILE_TYPE);
ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
File firstLocalFile = new File("D:/jetty.pdf");
String firstRemoteFile = "myfile.pdf";
InputStream inputStream = new FileInputStream(firstLocalFile);
System.out.println("Start uploading first file");
boolean done = ftpClient.storeFile(firstRemoteFile, inputStream);
inputStream.close();
if (done) {
System.out.println("The first file is uploaded successfully.");
} else {
System.out.println("upload failed");
}
} catch (IOException ex) {
System.out.println("Error: " + ex.getMessage());
ex.printStackTrace();
} finally {
try {
if (ftpClient.isConnected()) {
ftpClient.logout();
ftpClient.disconnect();
}
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
Each time the output is "upload failed". I don't understand where i am wrong.
Your port is incorrect. It uses:
FTPS via Auth TLS/SSL and implicit FTP over SSL on port 990
Also, if you read the site carefully, upload is forbidden:
Chilkat provides this FTPS test account for anyone wishing to test secure FTP client functionality. You may connect to ftp.secureftp-test.com, login as "test" with password "test", and download any files present on the server. The "test" account may also retrieve directory listings. However, it is restricted from uploading files to the server.

I'm trying to save pdf in wildfly, I'm using RestEasy MultipartFormDataInput provided with wildfly 20.0.1,
but it doesn't work.
This is what I have:
public static Response uploadPdfFile(MultipartFormDataInput multipartFormDataInput) {
// local variables
MultivaluedMap<String, String> multivaluedMap = null;
String fileName = null;
InputStream inputStream = null;
String uploadFilePath = null;
try {
Map<String, List<InputPart>> map = multipartFormDataInput.getFormDataMap();
List<InputPart> lstInputPart = map.get("poc");
for(InputPart inputPart : lstInputPart){
// get filename to be uploaded
multivaluedMap = inputPart.getHeaders();
fileName = getFileName(multivaluedMap);
if(null != fileName && !"".equalsIgnoreCase(fileName)){
try {
// write & upload file to UPLOAD_FILE_SERVER
//here I have the error: Unable to find a MessageBodyReader for media type:
//application/pdf
inputStream = inputPart.getBody(InputStream.class,InputStream.class);
uploadFilePath = writeToFileServer(inputStream, fileName);
}catch (Exception e) {
e.printStackTrace();
}
// close the stream
inputStream.close();
}
}
}
catch(IOException ioe){
ioe.printStackTrace();
}
finally{
// release resources, if any
}
return Response.ok("File uploaded successfully at " + uploadFilePath).build();
}
I'm using postman for test, http POST method, in the body I send: form-data - file and selected the file.pdf.
When I sent the request, I have the next RunTimeException when I try:
inputStream = inputPart.getBody(InputStream.class,null);
I get:
java.lang.RuntimeException: RESTEASY007545: Unable to find a MessageBodyReader for media type: application/pdf and class type org.jboss.resteasy.util.Base64$InputStream
At the moment I am saving the file receiving it in Base64, but I think that with MultipartFormDataInput it is the correct way.
This is what I have when debug:
Thanks for your support.
I solved this changing the InputStream from "org.jboss.resteasy.util.Base64.InputStream"
to "java.io.InputStream"
Today i wanted to switch from GCM to FCM so i set up everything needed and wanted to implement the server side code. I used the gcm4j library and changed it so that the adress goes to https://fcm.googleapis.com/fcm/send.
So im doing the following:
FCM fcm = new FCMDefault(new FCMConfig().withKey(FCMGlobals.FCM_API_KEY));
FCMRequest request = new FCMRequest().withRegistrationId(android.getRegistration())
// .withCollapseKey(collapseKey)
.withDelayWhileIdle(true)
.withDataItem(FCMGlobals.FCM_PARAM_CODE, code)
.withDataItem(FCMGlobals.FCM_PARAM_USER_ID, "" + user.getId())
.withDataItem(FCMGlobals.FCM_PARAM_ADDITION, "" + addition);
ListenableFuture<FCMResponse> responseFuture = fcm.send(request);
Futures.addCallback(responseFuture, new FutureCallback<FCMResponse>() {
public void onFailure(Throwable t) {
log.error(t);
}
#Override
public void onSuccess(FCMResponse response) {
log.info(response.toString());
}
});
The implementation for that is:
protected FCMResponse executeRequest(FCMRequest request) throws IOException {
byte[] content = this.objectMapper.writeValueAsBytes(request);
HttpURLConnection conn = this.connectionFactory.open(this.fcmUrl);
conn.setRequestMethod("POST");
conn.addRequestProperty("Authorization", getAuthorization(request));
conn.addRequestProperty("Content-Type", "application/json");
conn.setDoOutput(true);
conn.setFixedLengthStreamingMode(content.length);
LoggerFactory.getLogger("FCMDefaultAbstract").info("Authorization: " + conn.getRequestProperty("Authorization"));
LoggerFactory.getLogger("FCMDefaultAbstract").info("Content-Type: " + conn.getRequestProperty("Content-Type"));
LoggerFactory.getLogger("FCMDefaultAbstract").info("send: " + new String(content));
try (OutputStream outputStream = conn.getOutputStream()) {
IOUtils.write(content, outputStream);
} catch (Exception e) {
throw new FCMNetworkException("Error sending HTTP request to FCM", e);
}
FCMResponse response;
try (InputStream inputStream = conn.getInputStream()) {
response = this.objectMapper.readValue(IOUtils.toByteArray(inputStream), FCMResponse.class);
} catch (IOException e) {
try (InputStream inputStreamError = conn.getErrorStream()) {
String str = inputStreamError != null ? IOUtils.toString(inputStreamError) : "No error details provided";
int responseCode = conn.getResponseCode();
if (responseCode < 500) {
throw new FCMNetworkException(conn.getResponseCode(), str.trim(), e);
} else {
throw new FCMNetworkException(conn.getResponseCode(), str.trim(), checkForRetryInResponse(conn), e);
}
}
}
response.setRequest(request);
response.setRetryAfter(checkForRetryInResponse(conn));
Iterator<String> iteratorId = request.getRegistrationIds().iterator();
Iterator<FCMResult> iteratorResponse = response.getResults().iterator();
while (iteratorId.hasNext() && iteratorResponse.hasNext()) {
iteratorResponse.next().setRequestedRegistrationId(iteratorId.next());
}
if (iteratorId.hasNext()) {
LOG.warn("Protocol error: Less results than requested registation IDs");
}
if (iteratorResponse.hasNext()) {
LOG.warn("Protocol error: More results than requested registation IDs");
}
return response;
}
Here the log output:
FCMDefaultAbstract Authorization: null
FCMDefaultAbstract Content-Type:application/json
FCMDefaultAbstract send: {"registration_ids":["dMpvzp*************************************2lRsSl_5lFET2"],"data":{"CODE":"201","USER_ID":"1","ADDITION":"1468083549493"},"delay_while_idle":true}
FCM FCMNetworkException: HTTP 401: No error details provided
The Authorization header is not null in fact. it is correctly set with my FCM API Key. Only the HTTPUrlConnection implementation says to return null if someone trys to access Authorization key.
As you can see i am not able to connect with FCM. The Code 401 means that authentication failed.
What could be the problem here?
Check that you are using a server type API-KEY, and not a client or browser API-KEY.
If you are using Firebase you can find the API-KEY in
Project Settings > Cloud Messaging
If you are using cloud console, or you are not sure which key you are using,
you can generate a new key through through https://console.cloud.google.com
Quoting the documentation
https://firebase.google.com/docs/cloud-messaging/concept-options#credentials
Server key: A server key that authorizes your app server for access to
Google services, including sending messages via Firebase Cloud
Messaging. [...]
Important: Do not include the server key anywhere in your client code.
Also, make sure to use only server keys to authorize your app server.
Android, iOS, and browser keys are rejected by FCM.
I have a sftp server which i can connect manually using the command below
sftp -oport=4022 user#xxxxxx.com
but I am finding difficulty in doing the same with apache commons vfs.
Below is the method I am using to establish connection to the sftp server. But it not working and fails with the error "org.apache.commons.vfs2.FileSystemException: Could not connect to SFTP server at xxxxxx.com"
public boolean connect(String host, String login, String password,
int port) throws Exception {
//If the client is already connected, disconnect
if (command != null) {
disconnect();
}
FileSystemOptions fso = new FileSystemOptions();
try {
SftpFileSystemConfigBuilder.getInstance().setStrictHostKeyChecking(fso,
"no");
session =
SftpClientFactory.createConnection(host, port, login.toCharArray(),
password.toCharArray(),
fso);
System.out.println("pass");
Channel channel = session.openChannel("ssh");
channel.connect();
command = (ChannelSftp)channel;
} catch (FileSystemException e) {
throw e;
// return false;
}
return command.isConnected();
}
Please help me with this
Can someone explain to me whether following code is correct to download a certificate ties to a specific person in java? I am getting an exception as "unknown protocol: ldaps".
public void downloadCert() {
String urlStr="ldaps://aServerSomeWhere:636/cn=doe%20john,ou=personnel,o=comany123,c=us?caCertificate;binary";
URL url = null;
try {
url = new URL(urlStr);
URLConnection con = url.openConnection();
InputStream is = con.getInputStream();
CertificateFactory certFactory = CertificateFactory.getInstance("X.509");
X509Certificate cert = (X509Certificate)certFactory.generateCertificate(is);
System.out.println("getVersion: " + cert.getVersion());
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
No it isn't correct. There is no handler for the LDAPS: protocol in the URL/URLConnection system.
You can use JNDI to get the caCertificate attribute of that user, via DirContext.getAttributes().
I'm facing problems to send e-mails with Java Mail on Glashfish 3.1.1.
The server doesn't throw any Exception, just send an empty message with only header to recipient.
Running Java Mail without the Glashfish, everything works fine.
public void sendHtmlMessage(String subject, String html){
// Creates a email Session and
// and Authenticator attached to it
Session session = getMailSession();
try{
MimeMessage message = createMessage(session, subject, MailSender.MIME_Type.TEXT_HTML, html); // creates message
transportSMTPMessage(session, message); // transport message
} catch(AddressException e){ log("Internet address is invalid!"); e.printStackTrace(); }
catch(NoSuchProviderException e){ log("Host is invalid!"); e.printStackTrace(); }
catch(MessagingException e){ log("Message is invalid!"); e.printStackTrace(); }
catch(Exception e){ log("Gereric Exception!"); e.printStackTrace(); }
}
// Helper to obtain Mail Session
private Session getMailSession(){
Properties props = new Properties();
return Session.getInstance(props,
new Authenticator() {
#Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(userName, password);
}
});
}
// Helper to create MimeMessage
private MimeMessage createMessage(Session session, String subject, MailSender.MIME_Type mime, String content)
throws AddressException, MessagingException{
// Some code to create the message...
message.saveChanges();
return message;
}
// Helper to transpot the message thru the SMTP protocol
private void transportSMTPMessage(Session session, Message message)
throws NoSuchProviderException, MessagingException{
// Creates the transport connection and
// Send the message
Transport transport = session.getTransport("smtp");
transport.connect(host, userName, password);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
}
I think everything's fine with the code, I just don't understand, why it doesn't work on Glassfish?
I'd be grateful if someone help me.
Thanks in advance.
Call session.setDebug(true) in your application after creating the Session. Then look at the server log file to see if the JavaMail debug output has any clues about what's going wrong. I'm assuming you're not getting any exceptions.
