I can't write two times over the same file (java) -

-

I am writing in a text file, the first time a file output stream, and the second time through a file.

The file-optical stream text file looks just fine. However, FileWriter does not, after executing FileWriter, the contents of the file disappear, though it should be written to the file writer. Below is my code: 

  try {serverSocket = new ServerSocket (850); If (ServerSocket.isBound ()) System.out.println ("Saver socket not back ..."); Else System.out.println ("Server is surrounded by socket port:" + serverSocket.getLocalPort ()); ClientSocket = serverSocket.accept (); If (! ClientSocket.isConnected ()) System.out.println ("client socket is not connected ..."); Else System.out.println ("Client Socket Connected:" + clientSocket.getInetAddress ()); InputStream = clientSocket.getInputStream (); Int byteRead = 0; Byte [] bytere = new byte [1024]; // Type action in a file action file = new file ("C: \\ user \\ false \\ document \\ MATLAB \\ FYP.txt"); FileOutputStream fos = new FileOutputStream (actionfile); BufferedOutputStream Boss = New BufferedOutputStream (fos); While ((Bitrate = In. Raid (Biteyre, 0, Byterere Lamble)) gt; {) Boss. Written (byte, 0, byte read); } ServerSocket.close (); ClientSocket.close (); in.close (); Bos.close (); Fos.close (); Scanner scan = new scanner (actionfile); ActionChar = scan.next (). Chart (0); If (task charge == '1' || action == '2') {FileWriter fw = new FileWriter (actionFile); Buffedriver bi2 = new buffed waister (FW); PrintWriter pw2 = new print-वाटर (बीडब्ल्यू 2); pw2.write ('r'); } System.out.println ("action here:" + verb); } Hold (IOException e) {e.printStackTrace (); }  
 
 
 You have a  scanner  and   
 Read and close, then create the author.  
 And to close the call, make sure that for the same path name at the same time, open FileWriter . () After writing! It is unavailable.

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
