Writing to a server using a servlet

Question

does anyone know how to write a file (i.e. txt, htm, etc...) to a server using a servlet.
i'm using tomcat 4.0.1 and an IIS
i've been trying to figure out how to do this for a few days now and have not been able to figure it out.
can anyone show me how?
thanks
Andy

Answer 1

i got the above code working, but now when i try to pass a vector into the mix i'm not having any luck.
i haven't even been able to get a POST message to appear.
i think there is something wrong with my client-side code....
/*******applet********/
public void sendVector(Vector sendingVector)
URL baseURL = getCodeBase();
String protocol = baseURL.getProtocol();
String host = baseURL.getHost();
int port = 808;
try
String urlSuffix = "/servlet/contactlist.WriteToServlet";
URL servletURL = new URL(protocol, host, port, urlSuffix);
URLConnection conn = servletURL.openConnection();
// inform the connection that we will send output and accept input
conn.setDoInput(true);
conn.setDoOutput(true);
// Don't use a cached version of URL connection.
conn.setUseCaches (false);
conn.setDefaultUseCaches (false);
// Specify the content type that we will send binary data
conn.setRequestProperty ("Content-Type", "application/octet-stream");
// send the student object to the servlet using serialization
ObjectOutputStream outputToServlet = new ObjectOutputStream(conn.getOutputStream());
// serialize the object
outputToServlet.writeObject( sendingVector );
outputToServlet.flush();
outputToServlet.close();
} catch (IOException io) { io.printStackTrace(); }
} // end sendVector
/*********servlet*************/
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
try
// get an input stream from the applet
ObjectInputStream inputFromApplet = new ObjectInputStream(request.getInputStream());
// read the serialized student data from applet
Vector passInfo = (Vector)inputFromApplet.readObject();
inputFromApplet.close();
for(int i =0; i < passInfo.size(); i++) System.out.println(passInfo.get(i));
// make this so that the vector filename has no spaces
FileWriter writer = new FileWriter("G:\\Intranet\\wwwroot\\Contact\\contactlist\\Departments\\" + getFileTitle(passInfo.get(1).toString()) + ".htm");
// prints information to the file
int a;
for(a = 0; a < (passInfo.size()-1); a++)
{ writer.write(passInfo.get(a) + "\n");
writer.write(passInfo.get(a).toString());
writer.flush();
writer.close();
catch(Exception e) { e.printStackTrace(); }
public void doPut(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
doGet(request, response);
} // end doPut
