java.net.malformedurlexception: input string: "g@1234@ftp.xyz.com"     @ java.net.url.<init>(url.java:619)     @ java.net.url.<init>(url.java:482)     @ java.net.url.<init>(url.java:431)     @ createfolder.uploadfile(createfolder.java:39)     @ createfolder.main(createfolder.java:74) caused by: java.lang.numberformatexception: input string: "g@1234@ftp.xyz.com"     @ java.lang.numberformatexception.forinputstring(numberformatexception.java:65)     @ java.lang.integer.parseint(integer.java:492)     @ java.lang.integer.parseint(integer.java:527)     @ java.net.urlstreamhandler.parseurl(urlstreamhandler.java:217)     @ java.net.url.<init>(url.java:614)     ... 4 more 

you didn't provide error see couple of issues here:

1. connection string: know it's example if real user/pass contain '@' char, url won't parsed.
2. objectoutputstream class intended write object data can reconstructed objectinputstream (see here). it's not writing textual files. if need writing string stream better use printstream

so revised example be:

try {   url  url = new url("ftp://user:pass@ftp.xyz.com/testjar/2014-03-06-p.txt;type=i");   urlconnection urlc = url.openconnection();   outputstream os = urlc.getoutputstream(); // upload   outputstream buffer = new bufferedoutputstream(os);   printstream output = new printstream(buffer);   output.print("hiiiii");  } catch (ioexception ex) {     ex.printstacktrace(); } {    output.close();   buffer.close();   os.close(); }
