I am trying to call an https url inside my java application just after renaming a file in a ftp server directory.
The file is renamed and the https url request is succesfull however i am receiving a weird exception related to a certificate imported in my cacerts file.
The code that renames the file in ftp directory and then makes the https url request is the following:
...
FTPClient client = null;
try {
client = Ftp4jUtility.ftpsConnect1(SERVER_MACHINE, PORT, SERVER_USERNAME, SERVER_PASSWORD);
client.rename(oldDir, newDir);
renameStatus=true;
String url = config.getExtractZipUrl()+stdDet.getStudyDetailsCaseId(tmpNewFile.trim());
try {
JavaHttpsUrlConnectionReader(url);
} catch (Exception ex) {
Logger.getLogger(TranferFileFtp4j.class.getName()).log(Level.ERROR, null, ex);
}
client.logout();
client.disconnect(true);
} catch (IllegalStateException ex) {
log.info("Failed to rename: " + oldDir);
Logger.getLogger(TranferFileFtp4j.class.getName()).log(Level.ERROR, null, ex);
} catch (IOException | FTPIllegalReplyException | FTPException ex) {
log.info("Failed to rename: " + oldDir);
Logger.getLogger(TranferFileFtp4j.class.getName()).log(Level.ERROR, null, ex);
} finally {
if (client.isConnected()) {
try {
try {
client.logout();
client.disconnect(true);
} catch (IllegalStateException | FTPIllegalReplyException | FTPException ex) {
Logger.getLogger(TranferFileFtp4j.class.getName()).log(Level.ERROR, null, ex);
}
} catch (IOException ex) {
Logger.getLogger(TranferFileFtp4j.class.getName()).log(Level.ERROR, null, ex);
}
}
}
return renameStatus;
In my log i reveice:

and here is also the code (pretty simple) which is making the https url request:
public void JavaHttpsUrlConnectionReader(String myUrl) throws Exception {
URL url = null;
BufferedReader reader = null;
StringBuilder stringBuilder;
try {
url = new URL(myUrl);
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
// just want to do an HTTP GET here
connection.setRequestMethod("GET");
// give it 15 seconds to respond
connection.setReadTimeout(15*1000);
connection.connect();
// read the output from the server
reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
stringBuilder = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null)
{
stringBuilder.append(line + "\n");
}
//return stringBuilder.toString();
}
catch (Exception e)
{
e.printStackTrace();
throw e;
}
finally
{
// close the reader; this can throw an exception too, so
// wrap it in another try/catch block.
if (reader != null)
{
try
{
reader.close();
}
catch (IOException ioe)
{
ioe.printStackTrace();
}
}
}
}
Why am i receiving:
javax.net.ssl.SSLException: Unsupported record version Unknown-53.49
at sun.security.ssl.InputRecord.checkRecordVersion(InputRecord.java:552) at sun.security.ssl.InputRecord.checkRecordVersion(InputRecord.java:552)
and if you check further down:
java.lang.IllegalStateException: Client not authenticated
at it.sauronsoftware.ftp4j.FTPClient.logout(FTPClient.java:1406)
actually the line 390 in my code reffered to the log is where i am trying to:
client.disconnect(true);
So i am receiving the exception while i am trying to disconnect from the ftp session. Anybody has an idea why am i receiving this exception?
Finally it seems that
client.logout();
before:
client.disconnet(true);
was causing the exception:
java.lang.IllegalStateException: Client not authenticated
at it.sauronsoftware.ftp4j.FTPClient.logout(FTPClient.java:1406)
the:
javax.net.ssl.SSLException: Unsupported record version Unknown-53.49
at sun.security.ssl.InputRecord.checkRecordVersion(InputRecord.java:552) at sun.security.ssl.InputRecord.checkRecordVersion(InputRecord.java:552)
was due to an https request (HttpsURLConnection) with insufficient readTimeOut:
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setReadTimeout(15*1000);
connection.connect();
15 second was not enough. Increased to 60 and it was solved...
