Below is the code of my normal java program which works fine.
try {
// File destFile = new File("./SourceFiles/savedFile.txt");
File destFile = new File("./SourceFiles/", "savedFile.txt");
BufferedWriter writer = new BufferedWriter(new FileWriter(destFile));
writer.write("TESTing File Save");
writer.flush();
System.out.println("SAVED!!");
} catch ( IOException e ) {
e.printStackTrace();
Structure of this project is
Samples
|SaveSample
|SaveSample.java
|SourceFiles
|savedFile.txt
I have implemented similar code in my servlet too. But this doesnt save the content to the HTML file.
protected void doPost(HttpServletRequest request,
               HttpServletResponse response) throws ServletException, IOException {
          action = request.getParameter("action");
          try {
File destFile = new File("./SourceFiles/", "savedFile.html");
BufferedWriter writer = new BufferedWriter(new FileWriter(destFile));
writer.write(action);
writer.flush();
System.out.println("SAVED!!");
} catch ( IOException e ) {
e.printStackTrace();
Im getting FileNotFound Exception
java.io.FileNotFoundException: .\SourceFiles\savedFile.html (The system cannot find the path specified)
     at java.io.FileOutputStream.open(Native Method)
     at java.io.FileOutputStream.<init>(Unknown Source)
