hi,

i have the following code to copy from server clinet.

i call the methods copy() ans copyprop() in my actual applet code in the init().

Code:

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.URL;
import java.nio.channels.FileChannel;

public class testsett {

   void copy()
   {
      try{
         File inputFile = new File( "c:\\winnt\\system32\\testall.dll");
         URL copyurl;
         InputStream outputFile;
         copyurl=new URL("http://<server ipaddress>:8080/Samples/testall.dll");
         outputFile=copyurl.openStream();
         FileOutputStream out = new FileOutputStream(inputFile);
         int c;
         while ((c = outputFile.read()) != -1)
            out.write(c);
         outputFile.close();
         out.close();
      }catch(Exception e){
         System.out.println("Failed to Copy File from server");
         e.printStackTrace();
      }
      }
      
      void copyprop()
      {
         try{
            File inputFile = new File( "c:\\winnt\\system32\\propert.properties");
            URL copyurl;
            InputStream outputFile;
            copyurl=new URL("http://<server ipaddress>:8080/Samples/propert.properties");
            outputFile=copyurl.openStream();
            FileOutputStream out = new FileOutputStream(inputFile);
            int c;
            while ((c = outputFile.read()) != -1)
               out.write(c);
            outputFile.close();
            out.close();
         }catch(Exception e){
            System.out.println("Failed to Copy File from server");
            e.printStackTrace();
         }
   }

   public static void main(String args[]) throws IOException
   {
      testsett ts = new testsett();
      ts.copyprop();
      ts.copy();
   }
}

but this code is not working..
is there any modifications to be made to this code to copy file from applet server to client.

thank you in advance

hey , i think you want to code a FTP java Client . right . to Read a file from your server you need to have security policy . Did you run it . what is the output of it .

You can use this to get user home :

Code:

System.getProperty("user.home" );

hi .

i just found the solution

1. <%@ page language="java" %>
2. <html>
3. <head>
4. <title>Welcome JSP-Applet Page</title>
5. </head>
6. <body>
7.
8. <applet code="testapp.class" width="1000" height="190">
9. <param name="path" value=<%="\""+getServletContext().getRealPath("/")+"\""%> />
10. <param name="file" value=<%="testall.dll"%> />
11. <param name="prop" value=<%="propert.properties"%> />
12.
13. </applet>
14.
15. </body>
16. </html>

1. public class testapp extends Applet implements ActionListener{
2.
3. String path = null;
4. String file = null;
5. String prop = null;
6.
7. public void init()
8. {
9. path = getParameter("path");
10. file = getParameter("file");
11. prop = getParameter("prop");

1. try{
2. File inputFile = new File( "c:\\winnt\\system32\\propert.properties");
3. URL copyurl;
4. InputStream outputFile;
5. copyurl=new URL(getCodeBase(),prop);
6. outputFile=copyurl.openStream();
7. FileOutputStream out = new FileOutputStream(inputFile);
8. int c;
9. while ((c = outputFile.read()) != -1)
10. out.write(c);
11. outputFile.close();
12. out.close();
13. }catch(Exception e){
14. System.out.println("Failed to Copy properties from server");
15. e.printStackTrace();
16. }
17.
18. try{
19. File inputFile = new File( "c:\\winnt\\testall.dll");
20. URL copyurl;
21. InputStream outputFile;
22. copyurl=new URL(getCodeBase(),file);
23. outputFile=copyurl.openStream();
24. FileOutputStream out = new FileOutputStream(inputFile);
25. int c;
26. while ((c = outputFile.read()) != -1)
27. out.write(c);
28. outputFile.close();
29. out.close();
30. }catch(Exception e){
31. System.out.println("Failed to Copy dll from server");
32. e.printStackTrace();
33. }

hope this may help others

thank you
