copy files from applet server to client

ceazer

hi,

i have the following code to copy from server client(Applet application).

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

java 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" );

    <html>  
         <head>  
         <title>Welcome JSP-Applet Page</title>  
         </head>  
         <body>  
         
        <applet code="testapp.class" width="1000" height="190">  
                 <param name="path" value=<%="\""+getServletContext().getRealPath("/")+"\""%> />  
                <param name="file" value=<%="testall.dll"%> />  
                <param name="prop" value=<%="propert.properties"%> />  
              
         </applet>   
          
        </body>  
        </html>

public class testapp extends Applet implements ActionListener{

java code

String path = null;  
         String file = null;  
         String prop = null;  
       
         public void init()  
         {  
             path = getParameter("path");  
            file = getParameter("file");  
            prop = getParameter("prop");  



     try{  
                  File inputFile = new File( "c:\\winnt\\system32\\propert.properties");  
                 URL copyurl;  
                 InputStream outputFile;  
                 copyurl=new URL(getCodeBase(),prop);  
                   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 properties from server");  
                e.printStackTrace();  
           }  
              
            try{  
                File inputFile = new File( "c:\\winnt\\testall.dll");  
                URL copyurl;  
                InputStream outputFile;  
                copyurl=new URL(getCodeBase(),file);  
               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 dll from server");  
                e.printStackTrace();  
           }

hope this may help others
