Problem Solved! The issue was really about the RDP Protocol (Remote Desktop). There is a known bug documented in http://support.microsoft.com/kb/972828.
Here's a description of the RDP Problem: Files that are copied from a Windows Server 2008-based remote computer to a Windows XP SP3-based client computer by using the Remote Desktop Connection 6.1 client are corrupted Consider the following scenario. You have a remote computer that is running Windows Server 2008 and a client computer that is running Windows XP Service Pack 3. You use the Remote Desktop Connection 6.1 client to copy a file from the remote computer to the client computer. After the copy operation is complete, the size of the copied file is different to the size of the original file on the remote computer. Additionally, the copied file may be corrupted. Maybe it can help others! Ps. about your question, i use .toArray(). Thanks. 2010/5/10 Paulo Soares <psoa...@glintt.com> > Look like a problem with your transfer service.
