You can send multiple objects in a single request. On the applet side,
construct an ObjectOutputStream from the OutputStream for the connection, write
the objects you want to sent (which can include Strings giving information about
the transmission, for instance) to the ObjectOutputStream, and use the POST. On
the servlet side, construct an ObjectInputStream from the ServletInputStream,
read the objects in the same order they were written by the applet code, and
cast them back to the original types.
You can also set up a record containing all the items you want to transfer,
along the lines of:
public class Record
{
public String userName;
public String rudimentaryPassword;
public String nameOfFile;
public String nameOfSubdir;
...
}
Then set up all the information in an instance of this class on the client side,
output that to the ObjectOutputStream, and read it in on the server side. I
personally prefer to use pure data classes for this type of transfer, with no
methods defined, but that's a matter of taste.
