Call the action class from Applet

[Shyam Hai]

Hai,

I want to do file uploading from applet to action class.
How can i do.

But i tried file uploading from Applet to servlet.
its working fine.

But i need Applet to action class.

First i put the code for Applet to servlet.

Applet Class Code:

   
package com.hmh.in;
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import java.io.*;
import javax.swing.*;
 
public class TestApplet extends JApplet implements ActionListener
    {
     JButton jbutton = null;

     public void init()

         {

         jbutton = new JButton("Send file");

         jbutton.addActionListener(this);

         this.getContentPane().add(jbutton);

     }

      public void actionPerformed(ActionEvent ae)

         {

         if(ae.getSource() == jbutton)

             {

             try

                 {

                 File file = new File("c://Test//AppletTest.txt");
                 FileInputStream in = new FileInputStream(file);

                 byte[] buf=new byte[in.available()];

                 int bytesread = 0;
        
              [b]   String toservlet = "http://16.17.18.91:7001/DataAccess/MyServlet";[/b]
                

                 URL servleturl = new URL(toservlet);

                 URLConnection servletconnection = servleturl.openConnection();

                 servletconnection.setDoInput(true);

                 servletconnection.setDoOutput(true);

                 servletconnection.setUseCaches(false);

                 servletconnection.setDefaultUseCaches(false);
                 
                 DataOutputStream out=new DataOutputStream(servletconnection.getOutputStream());

                 while( (bytesread = in.read( buf )) > -1 )

                     {

                     out.write( buf, 0, bytesread );

                 }

                 out.flush();

                 out.close();

                 in.close();
              
          }

             catch(Exception e)

                 {  e.printStackTrace(); }

          }
         }
     }
 

Servlet Code :

 
package com.hmh.in;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class MyServlet extends HttpServlet
    {
     public void doPost(HttpServletRequest req,HttpServletResponse res)

         {

         ServletContext sc = this.getServletContext();

         try

             {

             String fileName = "getFromApplet.txt";

             String path = sc.getRealPath(File.separator)+fileName;

             System.out.println("fileName :"+fileName);

             File yourFile = new File(path);

             FileOutputStream toFile = new FileOutputStream( yourFile );

             DataInputStream fromClient = new DataInputStream( req.getInputStream() );

             byte[] buff = new byte[1024];

             int cnt = 0;

                 while( (cnt = fromClient.read( buff )) > -1 ) {

                 toFile.write( buff, 0, cnt );

             }

             toFile.flush();

             toFile.close();

             fromClient.close();
         }

         catch(Exception e)

             {         e.printStackTrace();       }

     }

}

web.xml :

              <servlet>
	<servlet-name>MyServlet</servlet-name>
	<servlet-class>com.hmh.in.MyServlet</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>MyServlet</servlet-name>
		<url-pattern>/MyServlet</url-pattern>
	</servlet-mapping>	

Its working fine.

But If i call Action class like this from applet.
it not working.

   
package com.hmh.in;
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import java.io.*;
import javax.swing.*;
 
public class TestApplet extends JApplet implements ActionListener
    {
     JButton jbutton = null;

     public void init()

         {

         jbutton = new JButton("Send file");

         jbutton.addActionListener(this);

         this.getContentPane().add(jbutton);

     }

      public void actionPerformed(ActionEvent ae)

         {

         if(ae.getSource() == jbutton)

             {

             try

                 {

                 File file = new File("c://Test//AppletTest.txt");
                 FileInputStream in = new FileInputStream(file);

                 byte[] buf=new byte[in.available()];

                 int bytesread = 0;
        
              [b]   String toservlet = "http://16.17.18.91:7001/DataAccess/myAction.do";[/b]
                

                 URL servleturl = new URL(toservlet);

                 URLConnection servletconnection = servleturl.openConnection();

                 servletconnection.setDoInput(true);

                 servletconnection.setDoOutput(true);

                 servletconnection.setUseCaches(false);

                 servletconnection.setDefaultUseCaches(false);
                 
                 DataOutputStream out=new DataOutputStream(servletconnection.getOutputStream());

                 while( (bytesread = in.read( buf )) > -1 )

                     {

                     out.write( buf, 0, bytesread );

                 }

                 out.flush();

                 out.close();

                 in.close();
              
          }

             catch(Exception e)

                 {  e.printStackTrace(); }

          }
         }
     }
 

Its not working.
