import javax.imageio.ImageIO;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
 
import java.awt.image.BufferedImage;
import java.io.*;
 
import org.apache.struts.action.Action;

[B]   BufferedImage bi =(BufferedImage) myForm.getTheFile();// retrive image
     // getting root context //
   String path=request.getContextPath()+"/src";
   System.out.println("path changetd==="+path);
   //Saving image in file//
   outfile = new File("path");
  // ImageIO.write();[/B]
}
catch(Exception e)
{
e.printStackTrace();
}

// Process the FormFile
FormFile myFile = myForm.getTheFile();
String contentType = myFile.getContentType();
String fileName    = myFile.getFileName();
String name=(String)session.getAttribute("satya");
System.out.println("getAttribute=="+name);
String newfile=fileName.replaceAll("fileName","name");



int fileSize       = myFile.getFileSize();
byte[] fileData    = myFile.getFileData();
System.out.println("contentType: " + contentType);
System.out.println("File Name: " + fileName);
System.out.println("File Size: " + fileSize);

return mapping.findForward("success");
}
}

Retriving the image from form bean and displaying it height gives error

[B] BufferedImage bi =(BufferedImage) myForm.getTheFile();// retrive image
  System.out.println("height of image"+bi.getHeight());[/B]

That's because your trying to convert a FormFile object into a BufferedImage in this line

try
{
 BufferedImage bi =[B](BufferedImage) myForm.getTheFile();[/B]//retrive image  ...
} catch(Exception e) {
  e.printStackTrace();
}

I suppose that myForm.getTheFile() returns a FormFile because you later have this line:

// Process the FormFile
FormFile myFile = myForm.getTheFile();

Q2) Is it possiable to store image in mysql? if possiable ? how?

Yes. You can store it in a BLOB. This link shows you how.
