java - FTPClient.storeFile() returning false and FTP return code is 450 and says file is busy -

my requirement write file file server , connectivity or issues while writing file file server need draft mail.

while testing below code in testing environment business,client.storefile returning false few files .we placing files manually in target file server failed ones.it not expected in prod environment .any thoughts on might reason ?

fyi:business testing uploading many files.

my code:

int timeout = timeout * 1000; //variable store connection timeout abstracttrace trace = container.gettrace(); fileinputstream fis = null; ftpclient client = new ftpclient(); //creating ftpclient instance try{ ftpclientconfig conf = new ftpclientconfig(ftpclientconfig.syst_unix); conf.setdefaultdateformatstr(dateformat); client.configure(conf); try{ client.setconnecttimeout(timeout); //setting connection timeout client.connect(host);// connecting ftp server if(!client.login(username, pwd)){ throw new streamtransformationexception("authorization failed.");} //giving credentials login trace.addinfo("successfully connected server"+client.getreplystring()); if(!client.changeworkingdirectory(folderpath)){ throw new streamtransformationexception("exception occurred while changing folder path interface specific path.");} //changing current directory required folder path } catch(exception c){ throw new streamtransformationexception("exception occured while connecting server :" + c); }//close brace grab // create inputstream of file uploaded string srcfilename = filename+"_temp"+new date().gettime(); string targetfilename = filename+"_"+new date().gettime(); file sourcefile =new file(srcfilename); //if file doesn't exists, create if(!sourcefile.exists()){ sourcefile.createnewfile();} filewriter filewritter = new filewriter(sourcefile.getname(),true); bufferedwriter bufferwritter = new bufferedwriter(filewritter); bufferwritter.write(input); //writing input payload file bufferwritter.close(); fis = new fileinputstream(sourcefile); boolean done = client.storefile(targetfilename, fis); //store file server fis.close(); if (done) { trace.addinfo("!!!----file uploaded successfully----!!!"); } else { trace.addwarning("upload failed"); throw new streamtransformationexception("failed upload file :please cross check..:"); } //close brace else client.logout(); }catch(exception e){ try{ properties properties = system.getproperties(); // scheme properties properties.setproperty("mail.smtp.host",mail_host); // setup mail service server //session session = session.getdefaultinstance(properties); // default session object. session session = session.getinstance(properties); // if unknown host exception in java //sending mail service app back upwards folks mimemessage message = new mimemessage(session); // create default mimemessage object. message.setfrom(new internetaddress(mail_from)); // set from: header field of header. string recipients[] =mail_to.split(";"); internetaddress[] addressto = new internetaddress[recipients.length]; (int = 0; < recipients.length; i++) { addressto[i] = new internetaddress(recipients[i]); } message.setrecipients(message.recipienttype.to, addressto); //message.addrecipient(message.recipienttype.to,new internetaddress(mail_to)); // set to: header field of header. message.setsubject(mail_subject); // set subject: header field message.settext(e.getmessage()+"."+" failed message having field value of "+fieldname+" "+returnfieldname); // set actual message transport.send(message); // send message trace.addinfo("sent alert mail service app back upwards folks successfully"); }catch(exception mex){ trace.addwarning("failed send alert mail service : "+mex); }//close brace grab } //close brace grab { seek { if (fis != null) { fis.close(); } client.disconnect(); } grab (ioexception k) {trace.addwarning("exception while closing filestream , diconnecting"+k); } } //close brace homecoming "file placed successfully";

hi first seek find reply receiving method storefile()

ftp.getreplystring()

use system.out.println , find out problem ftp.

java file-upload
