jakarta fileupload - suggestions to improve my code

[Alessandro Ilardo]

Basically I've a servlet which receives a multipart request. With that it should create a new object which should save the file and store the path to be later added on a database.

My problem, or doubt is about the constructor's object
this's the code:

    public Master(List items, String path) throws Exception {
        try{
            // Process the uploaded items
            Iterator iter = items.iterator();
            while (iter.hasNext()) {
                FileItem item = (FileItem) iter.next();
                if (item.isFormField()) {
                    if(item.getFieldName().equalsIgnoreCase("id") &&
                            item.getString()!=null) this.setId(
                                    new Integer(item.getString()).intValue());
                    
                    if(item.getFieldName().equalsIgnoreCase("creationDate") &&
                            item.getString()!=null) this.getParsedFormDate(
                                    item.getString(),0);
                    
                    if(item.getFieldName().equalsIgnoreCase("title") &&
                            item.getString()!=null) this.setTitle(
                                    item.getString());
                    
                    if(item.getFieldName().equalsIgnoreCase("description") &&
                            item.getString()!=null) this.setDescription(
                                    item.getString());
                } else {
                    if(item.getFieldName().equalsIgnoreCase("attachment")){
                        File folder = new File(path);
                        if(!folder.exists()){
                            folder.mkdir();
                        }
                        File uplFile = new File(path,item.getName());
                        item.write(uplFile);
                        this.setAttachmentPath(uplFile.getAbsolutePath());
                    }
                }
            }
        }catch(Exception ex){
            logger.fatal("MultiPart Constructor - ", ex);
            throw new Exception(ex);
        }
    }

1. Is another way to get the field's value without going trough an Iterator?
2. How would you improve it?

Thanks in advance.
