Hi all,
I am using FileReference in my application.. In bachend i am
using servlet.. now the problem is that I am able to call servlet
successfully.. but i am getting error for following line
FileItem items = upload.parseRequest( req );
where upload is object of ServletFileUpload..
Error is :
IOErrorEvent type="ioError" bubbles=false cancelable=false
eventPhase=2 text="Error #2038: File I/O Error. URL:
http://localhost:8400/FileUpload/uploadservlet";
Pl tell me where am i wrong?? Pl help me ..
My servlet code is:
// Core classes
import java.io.File;
import java.io.IOException;
import java.util.Iterator;
import java.util.List;
// Servlet classes
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
// Commons classes
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileItemFactory;
import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
// Sample file upload servlet
public class UploadFileServlet extends HttpServlet
{
// Called when a file has been submitted
// Called because file uploads are HTTP POST operations
public void doPost( HttpServletRequest req, HttpServletResponse res )
{
// Setup the various objects used during this upload operation
// Commons file upload classes are specifically instantiated
File disk = null;
FileItem item = null;
FileItemFactory factory = new DiskFileItemFactory();
Iterator iter = null;
List items = null;
ServletFileUpload upload = new ServletFileUpload( factory
);
ServletOutputStream out = null;
System.out.println("=======================================Got
request========================================");
/*File f = new File("signal.sig");
try{
f.createNewFile();
}catch(java.io.IOException exception){}*/
try
{
// Parse the incoming HTTP request
// Commons takes over incoming request at this point
// Get an iterator for all the data that was sent
// TODO: Leverage generics
System.out.println("=======================================Before
parsing ========================================");
items = upload.parseRequest( req );
System.out.println("=======================================After
parsing ========================================");
iter = items.iterator();
// Set a response content type
res.setContentType( "text/xml" );
// Setup the output stream for the return XML data
out = res.getOutputStream();
out.println( "<response>" );
// Iterate through the incoming request data
while( iter.hasNext() )
{
// Get the current item in the iteration
item = ( FileItem )iter.next();
// If the current item is an HTML form field
if( item.isFormField() )
{
// Return an XML node with the field
name and value
out.println( "<field name=\"" +
item.getFieldName() + "\" value=
\"" + item.getString() + "\" />" );
// If the current item is file data
} else {
// Specify where on disk to write the
file
// Using a servlet init param to
specify location on disk
// Write the file data to disk
// TODO: Place restrictions on upload
data
disk = new File( getInitParameter(
"uploadPath" ) + item.getName
() );
// disk = new
file(getServletContext().getRealPath(getInitParameter
(”uploadPath”)) + “\\” + item.getName() );
item.write( disk );
// Return an XML node with the file
name and size (in bytes)
out.println( "<file name=\"" +
item.getName() + "\" size=\"" +
item.getSize() + "\" />" );
}
}
// Close off the response XML data and stream
out.println( "</response>" );
out.close();
// Rudimentary handling of any exceptions
// TODO: Something useful if an error occurs
} catch( FileUploadException fue ) {
fue.printStackTrace();
} catch( IOException ioe ) {
ioe.printStackTrace();
} catch( Exception e ) {
e.printStackTrace();
} finally{
}
}
public void doGet( HttpServletRequest req, HttpServletResponse res )
{
doPost(req,res);
}
}
My ActionScript Code:
uploadURL.url = "http://localhost:8400/FileUpload/
uploadservlet";
file = FileReference(event.target);
file.upload(uploadURL,"Filedata",false);
It goes upto the "before parsing" stmt after that its giving me the
error ..
Pl help me ..
Thanks in advance

Akshay
