Can we transfer a file to a windows machine a

[PC Varma]

Recently I saw the j-Interop, Amazingly it’s a awesome COM bridge. I tried this for our internal R&D. While doing, we have a requirement. “We have a tiny application as a msi package, we want to install this package across all the widows machines in the having a common administration windows domain account.”. We can do this from a windows machine, but in our deployment, we don’t want to use a windows machine, we would love to use the j-interop.

                Can we transfer a file to a windows machine and invoke/run the same file? Using j-interop? Any suggestions?, welcome

seems like you're trying to do this the hard way…. You can install MSIs as group policy objects in an Active Directory domain. 
See:

If you want to do this in the manner you describe above, then you should put the MSI in a share with file share access, then you could use a remote command execution to execute the MSI.  To do the remote execution you need to create a new instance of a Win32\_Process.  See  for some C#/VB examples, but the mindeset is similar.  Create the Win32_Process set the cmd line properties on it, then execute the "Create" method on the Win32\_Process.

Hi Scottley
    Thanks for your quick reply. We did the similar approach with C++/xCmd.exe. it was fine. But, mine is a linux appliance, i can't run win_32 apps on linux and no common shares and no Windows Domain.

I just have linux and java/j-interop. please help me out.

Thanks in advance

Hi All

    I wrote a program to copy file from my linux box to a windows box with API. Its working fine for other than binary files.

   But i need to copy the binary file. i have attached the code, please help me out.

Basically, i need to read the binsry data and write the binary data to the stream as byte array, but with j-interop… i could create JIByteArray or JIArray with java Byte Array data.
