Hi Hung Our JCR supports big files uploading without "Out of memory" error but ECM doesn't. Could u pls modify sources such as UIUploadForm.java and related files, we should use another stream than ByteArrayInputStream (
e.g. InputStream). Because of array of bytes transformations we have "Out of memory" error. If u'll implement this logic we could upload big files (750M and greater using ECM) such as video films etc. without "Out of memory" error.
