1)MultipleFileUpload.java

import java.io.File;
    import java.util.ArrayList;
    import java.util.List;

    import com.opensymphony.xwork2.ActionSupport;

    public class MultipleFileUpload extends ActionSupport{

        private List<File> fileUpload = new ArrayList<File>();
        private List<String> fileUploadContentType = new ArrayList<String>();
        private List<String> fileUploadFileName = new ArrayList<String>();

        public List<File> getFileUpload() {
            return fileUpload;
        }

        public void setFileUpload(List<File> fileUpload) {
            this.fileUpload = fileUpload;
        }

        public List<String> getFileUploadContentType() {
            return fileUploadContentType;
        }

        public void setFileUploadContentType(List<String> fileUploadContentType) {
            this.fileUploadContentType = fileUploadContentType;
        }

        public List<String> getFileUploadFileName() {
            return fileUploadFileName;
        }

        public void setFileUploadFileName(List<String> fileUploadFileName) {
            this.fileUploadFileName = fileUploadFileName;
        }

        public String upload() throws Exception{

            for (File file: fileUpload) {
                System.out.println("File :" + file);
            }

            for (String fileName: fileUploadFileName) {
                System.out.println("Filename : " + fileName);
            }

            for (String fileContentType: fileUploadContentType) {
                System.out.println("File type : " + fileContentType);
            }

            return SUCCESS;

        }

        public String display() {
            return NONE;
        }

    }
