What is the best way to send a file?

Question

i am writing a program and i want to transfer a file from a client class to a server class... what is the best way to do that?
convert the file to bytes using the following
File file=new File("jobs.xml");
           byte buffer[]=new byte[(int)file.length()];
           try {
                BufferedInputStream input=new BufferedInputStream(new FileInputStream("jobs.xml"));
                input.read(buffer,0,buffer.length);
                input.close();
           } catch(Exception e) {//DIORTHOSE TA MSGS
              System.out.println("reading jobs.xml->buffer: "+e.getMessage());
              e.printStackTrace();
           firstServerRef.translationService(theCallbackObjectRef, buffer);for a reason i dont like that i am reading the file again to put it in the buffer and send the buffer... are my worries reasonable or not? is there any other better way to do that?

Answer 1

Use a smaller buffer, repeatedly read and
write, and print the exception's stack trace.
What do you mean by reading again, by the way? I only
see you reading the file once.hmm you mean use a smaller buffer and call the function with the smaller buffer many times in a while?
the client and the server are not on a single machine and i want to call the function only once... could you clarify the thing that you said..
yes you are correct that you see only one reading because i haven't pasted the rest of the code which is sth like...
FileWriter fw = new FileWriter("jobs.xml");
           ObjectOutputStream out = xstream.createObjectOutputStream(fw);
     //      out.writeObject(new Jobb("ougk2", "Walnes",null));
          for(int i=0;i<nameOfServices.length;i++){
               Jobb translationJob=new Jobb();
               //find the service !
             NameComponent nc = new NameComponent(nameOfServices, " ");
// Resolve the object reference in naming
NameComponent path[] = {nc};
//create a ref for the servant of the service
ServiceOperations theRemoteObjRef = ServiceHelper.narrow(ncRef.resolve(path));
// JobOperations theRemoteObjRef = JobHelper.narrow(ncRef.resolve(path));
translationJob.setObjServerRef(theRemoteObjRef.toString());
if(i==0){ //this is the first job
     translationJob.setForTranslation(wordForTranslation);
     firstServerRef=theRemoteObjRef;
     out.writeObject(translationJob);
     out.close();
     File file=new File("jobs.xml");
          byte buffer[]=new byte[(int)file.length()];
          try {
               BufferedInputStream input=new BufferedInputStream(new FileInputStream("jobs.xml"));
               input.read(buffer,0,buffer.length);
               input.close();
          } catch(Exception e) {//DIORTHOSE TA MSGS
     System.out.println("reading jobs.xml->buffer: "+e.getMessage());
     e.printStackTrace();
          firstServerRef.translationService(theCallbackObjectRef, buffer);
which i believe is bad....
