Applet + write to file

[Henrik Kier]

Hello

I am trying to write to a file located on the server from an applet.

The code I am trying to do this with is:

try{
URL url1 = new URL(proto,host,file);
URLConnection urlcon1 = url1.openConnection();
urlcon1.setDoInput(true);
urlcon1.setDoOutput(true);
urlcon1.setUseCaches(false);
urlcon1.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
DataOutputStream dos = new
DataOutputStream(urlcon1.getOutputStream());
dos.writeBytes(str);
dos.flush();
dos.close();
} catch (Exception ex)
{
ex.printStackTrace();
}
}

but when I run this on the server it just says opening file and it just
stays tha way, it newer opens??

Can someone help me

You need to actually make the connection, either with connect() or by
getting the input stream. I suggest getting the input stream and just
closing it.

You've got to get the input stream *after* the output stream - you've
got to write the complete request before you can get the response!

Hallo

Now I have don that and I am still getting no way.

The code is like this now:

try{
URL url1 = new URL(proto,host,filx);

URLConnection urlcon1 = url1.openConnection();
urlcon1.setDoInput(true);
urlcon1.setDoOutput(true);
urlcon1.setUseCaches(false);
urlcon1.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");

DataOutputStream dos = new
DataOutputStream(urlcon1.getOutputStream());
dos.writeBytes(str);
dos.flush();
dos.close();

DataInputStream dis = new DataInputStream(urlcon1.getInputStream());

String s1 = dis.readLine();
if(dis != null && Integer.parseInt(s1) >= 0)
System.out.print("we make it" + Integer.parseInt(s1));
else
System.out.print("we did't make it");
dis.close();
}catch (Exception ex)
{
ex.printStackTrace();
}

And the file I am trying to get is set to chmod 777 - but now I am getting
this error:
java.io.IOException: Connection failure with 405
at
sun.plugin.protocol.jdk12.http.HttpURLConnection.getInputStream(Unknown
Source)
in the line:

DataInputStream dis = new DataInputStream(urlcon1.getInputStream());

Can someone help me??

What appears in the logs at the server end? I can't remember off-hand
what HTTP code 405 means - I suggest you look it up in the HTTP RFCs.

[Henrik Kier]

hallo

It means "405 Method Not Allowed" and it in line:

"DataInputStream dis = new DataInputStream(urlcon1.getInputStream());"

please help me!!!

That probably means it's using GET instead of POST or vice versa.

And what appears in the logs at the server end (as I asked before)?

[Henrik Kier]

Hmm... that's odd.

And does your servlet have a doGet method?

[Henrik Kier]

method

Your applet wouldn't have a doGet method, obviously - but does the
server page you're after accept post request (like the one you're
making)?
