    <p>I'm making a Client-Server. I've gotten as far as that the server can send a hardcoded file, but not a client specified. I will have to send only text files. As far as I have understood: the clients firstly sends the file name and then, the server sends it, nothing complicated, but I'm getting all kinds of errors, this code is getting a connection reset/socket closed error. The main problem is, that hadn't got much time to research networking.</p> <p>Ill appreciate any help I can get.</p> <p><strong>EDIT.</strong> I found a work around, closing a stream causes the socket to close, why is that? It shouldn't happen, should it?</p> <p>Server Side:</p> <pre><code> InputStream sin=newCon.getInputStream(); DataInputStream sdata=new DataInputStream(sin); location=sdata.readUTF(); //sdata.close(); //sin.close(); File toSend=new File(location); byte[] array=new byte[(int)toSend.length()]; FileInputStream fromFile=new FileInputStream(toSend); BufferedInputStream toBuffer=new BufferedInputStream(fromFile); toBuffer.read(array,0,array.length); OutputStream out=newCon.getOutputStream(); //Socket-closed... out.write(array,0,array.length); out.flush(); toBuffer.close(); newCon.close(); </code></pre> <p>ClientSide:</p> <pre><code>int bytesRead; server=new Socket(host,port); OutputStream sout=server.getOutputStream(); DataOutputStream sdata=new DataOutputStream(sout); sdata.writeUTF(interestFile); //sdata.close(); //sout.close(); InputStream in=server.getInputStream(); //socket closed.. OutputStream out=new FileOutputStream("data.txt"); byte[] buffer=new byte[1024]; while((bytesRead=in.read(buffer))!=-1) { out.write(buffer,0,bytesRead); } out.close(); server.close(); </code></pre>

    1. COHave you tried System.out.println(sdata.available()) before reading? Maybe there's nothing to read yet.

    3. CObut does it get to location=sdata.readUTF(), where you say the connection is reset? I mean before that.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
