Hello All,

If I put follwing code in JSP , It works fine and uploads the file

boolean isMultipart = FileUpload.isMultipartContent(request);
System.out.println("MultiPart is "+isMultipart);
DiskFileUpload upload = new DiskFileUpload();
// Set upload parameters
upload.setSizeMax(1000000);
List /* FileItem */ items = upload.parseRequest(request);
System.out.println("items.size =" + items.size());
Iterator itr = items.iterator();
while(itr.hasNext()) {
FileItem fi = fi= (FileItem)itr.next();

//Check if not form field so as to only handle the file inputs
//else condition handles the submit button input
if(!fi.isFormField()) {
System.out.println("\nNAME: "+fi.getName());
System.out.println("SIZE: "+fi.getSize());
//System.out.println(fi.getOutputStream().toString());
System.out.println("App.getrealpath() ="+ servlet.getServletContext().getRealPath("/") );
File fNew= new File(servlet.getServletContext().getRealPath("/"), fi.getName());
System.out.println(fNew.getAbsolutePath());
fi.write(fNew);
}
else {
System.out.println("Field ="+fi.getFieldName());
}
}

but If I put that code in Action Class , List /* FileItem */ items is empty set, i.e items.size is ZERO !!

Can anybody enlighten me on this ??

Thanks in Advance.
-Anand.

First, I wonder how you put the codes in JSP? When you submit the form in one JSP, you submit to another JSP?


but If I put that code in Action Class , List /* FileItem */ items is empty set, i.e items.size is ZERO !!

Can anybody enlighten me on this ??


In fact, if you use Struts, you dont need to use Jakarta Common FileUpload. Struts has a built-in class FormFilefor file upload:



Hope this help.

import org.apache.struts.upload.FormFile;


And for more information about struts-upload, you can see more example in struts-upload.war in struts.zip (downloaded for apache.org)
