使用SOAP Web服务上传大文件

Question

I need to upload a file which is vary from 10-100mb. When I try to upload the file, it gives me outofmemory error in line

sb.append(Base64.encode(data));

How can I solve this issue? My web service is SOAP webservice. Here is the complete code of the method.

 public static String fileToBase64(String path) throws IOException {
            File imagefile = new File(path);
            byte[] data = new byte[3000];
            FileInputStream fin = null;
            StringBuffer sb = new StringBuffer();
            try {
                fin = new FileInputStream(imagefile);
                while(fin.read(data) >= 0) {
                   sb.append(Base64.encode(data));
               }
                return sb.toString();
            } catch (Exception e) {
                // TODO: handle exception
            } finally{
                fin.close();
            }
            return null;
        }

I see two methods:

1. Use streamed XML writer and chunked content to avoid excessive memory consumption. Not sure if it is applicable here.

2. Use MTOM to send SOAP messages with attachments.

This method is preferable, but you must add required functionality to your webservice.
