Problem with the streams....

Question

Dear All,
I am trying to zip a file in the client side and sending it to the server side machine......there, i am trying to unzip it and writting it over there...for this, i am using a seperate program in the client side and in the server side.................................
In the client program, after opening all the necessary streams and all formalities, i am using the code...
"InputStream in = urlconnection.getInputStream();
while (in.read()!=-1);"
only if i use the above code, the zipped file is transfered to my server machine...but in this case, the link with the server is not getting disconnected...i mean the command prompt remains alive, without stopping...what i inferred is, my control is got into the above said "InputStream in = urlconnection.getInputStream();"...indefinitely...
so i tried of removing the above said statement.....in this case, the zipped file is NOT getting written in my server machine....
what to do???
any suggestions please...waiting for the reply very anxiously, refreshing this site for every 2 minutes....
sakthivel s.
snippet code for ur reference...
Client side
try
ZipOutputStream zipoutputstream = new ZipOutputStream(urlconnection.getOutputStream());
ZipEntry zipentry = new ZipEntry(filename);
zipentry.setMethod(ZipEntry.DEFLATED);
zipoutputstream.putNextEntry(zipentry);
byte bytearray[] = new byte[1024];
File file = new File(filenamedir);
FileInputStream fileinputstream = new FileInputStream(file);
BufferedInputStream bufferedinputstream = new BufferedInputStream(fileinputstream);
int length = 0;
while((length=bufferedinputstream.read(bytearray)) != -1)
zipoutputstream.write(bytearray,0,length);
fileinputstream.close();
bufferedinputstream.close();
zipoutputstream.flush();
zipoutputstream.finish();
zipoutputstream.closeEntry();
zipoutputstream.close();
InputStream in = urlconnection.getInputStream();
while (in.read()!=-1); // the said while loop....................
System.runFinalization();
urlconnection.getInputStream().close();
urlconnection.disconnect();
the way of connecting witht the server : (just a snippet of the code)
URL serverURL = new URL("http://192.168.10.55:8001/servlet/uploadservlet");
HttpURLConnection.setFollowRedirects(true);
urlconnection= (HttpURLConnection)serverURL.openConnection();
urlconnection.setDoOutput(true);
urlconnection.setRequestMethod("POST");
urlconnection.setDoOutput(true);
urlconnection.setDoInput(true);
urlconnection.setUseCaches(false);
urlconnection.setAllowUserInteraction(true);
urlconnection.setRequestProperty("Cookie",cookie);
urlconnection.connect();
Server Side:
javax.servlet.ServletInputStream servletinputstream = httpservletrequest.getInputStream();
ZipInputStream zipinputstream = new ZipInputStream(servletinputstream);
ZipEntry zipentry = null;
String directory="c:\\test"; // the unzipped file should be written to this directory...
try
File file = new File(directory);
if(!file.exists())
file.mkdirs();
catch(Exception exp)
{System.out.println("I am from Server: " + exp);}
try
zipentry = zipinputstream.getNextEntry();
if(zipentry != null)
int slash = zipentry.getName().lastIndexOf(File.separator) + 1;
String filename = zipentry.getName().substring(slash);
File file1 = new File(directory + File.separator + filename);
FileOutputStream fostream = new FileOutputStream(file1);
BufferedOutputStream bufferedoutputstream = new BufferedOutputStream(fostream);
byte abyte0[] = new byte[1024];
for(int index = 0; (index = zipinputstream.read(abyte0)) > 0;)
bufferedoutputstream.write(abyte0, 0, index);
servletinputstream.close();
bufferedoutputstream.flush();
bufferedoutputstream.close();
zipinputstream.closeEntry();
zipinputstream.close();
fostream.flush();
fostream.close();
catch(IOException ioexception)
{System.out.println("IOException occured in the Server: " + ioexception);ioexception.printStackTrace();}
P.S: I am not getting any error in the server side or cleint side...the only problem is, the command prompt(where i am running my cleint program) is getting standing indefinitely...i have to use control-c to come to the command prompt again...this is because of the while looop said in the client machine....if i remove it...the file is not gettting transfered...what to do????

Answer 1

Some thoughts:
1) please quote your code so it's readable (see http://forum.java.sun.com/faq.jsp#messageformat ).
2) why are you calling "System.runFinalization();"?
3) Offhand I don't see where the read would ever stop. It's waiting for an end of input from the server, but the server doesn't even begin to write output to it. What happens when you connect to your server with a browser or some other client?
4) is it really wise to read and write one byte at a time?
