Hi everybody,
I have the problem with ArgoUML extension that I'm developing for my research.
It uses commons-net to upload an ArgoUML project (.zargo archive) and its
diagrams as png pictures to the remote FTP server. Its works fine in case FTP
client and FTP server are on the same PC. Today, I have tried to test it with
my students in a LAN and I had a situation that only few students could upload
their projects to the server. Most of the uploaded projects had failed. Some of
them have size 0 KB, some of them has several KBs size, but seems to be
damaged. The pictures are also unreadable in most cases or in some cases only
upper part of the picture is uploaded.
Do you have any idea what is the problem? Is it possible to use FTP client for
this, and if not what could be better solution?
The code is given bellow.

public static void uploadFileToRepository(File file,String fName){
String fileName=null;
try{
int bufferSize=8192;
ftp.setFileType(FTP.IMAGE_FILE_TYPE);
if (fName.equals(".png")){
fileName=file.getName();
ftp.changeWorkingDirectory("/images");
}else if (fName.equals(".zargo")){
try{
fileName="Project_"+ProjectUtility.getCurrentProject().getProjectId()+".zargo";
}catch(Exception e){
ProjectUtility.getNewProject().setProjectValues();
try{
fileName="Project_"+ProjectUtility.getCurrentProject().getProjectId()+".zargo";
}catch(Exception ee){
DepthsExceptionMessage.showExceptionMessage("Problem to create
project"+ee.getMessage()+"\n\n"+ee.getCause());
}
}
ftp.changeWorkingDirectory("/projects");
}
InputStream fis = new FileInputStream(file);
OutputStream os = ftp.storeFileStream(fileName);
int bytesRead = -1;
final byte[] buffer = new byte[bufferSize];
while ((bytesRead = fis.read(buffer)) != -1)
{
os.write(buffer, 0, bytesRead);
}
os.flush();
os.close();
}catch(IOException ioe){
DepthsExceptionMessage.showExceptionMessage(ioe.getMessage()+"\n\n"+ioe..getCause());
}catch(Exception e){
LOG.debug("Exception:"+e.getClass().getName());
DepthsExceptionMessage.showExceptionMessage(e.getMessage()+"\n\n"+e.getCause()+"\n\n");
}
}
