ProfileTokenCredentials for current user

Hello,
        I need to be able to get the ProfileTokenCredential for the
current user so I can use them on a remote system connecting back to the
400 they originated on. Basically, I need this so I can copy files from
a remote system back to the 400 and have them created on the 400 with
the owner being the user that signed into the 400. For clarification:

1) user signs in to 400.
2) user submits a job that makes an RMI call to a Windows PC.
3) the Java on the PC copies files from it's local drive or a network
share to the 400 using the Toolbox IFSFile and related classes.
4) I need to files created on the IFS to have the owner set to the user
that initiated the process.

NOTE: Currently, the file copy from the PC is done using a pre-defined
user to which I know the password. However, I need it to be done in this
case using the current user from the 400.

Eventually the process returns to the Java on the 400. I tried going
through the directory the files are copied to and setting all the owners
on the files to the current user. However, the user that I typically use
to do copy the files to the 400 does not have *USE authority to the user
profile that I need to change the file ownership too. I cannot give the
user I typically use *USE authority to the profile.

So, my next idea was to create a ProfileTokenCredential that I could
pass to the PC so that the PC could use it to create the files on the
IFS so they would end up with the correct owner. However, since I don't
know the current users password on the 400, I can't create credentials
for them. I know they have authenticated since they are the user running
the program, and I can create an AS400 object using *CURRENT, but it
won't let me get credentials from that AS400 system object (as
documented). Is there a way to get the credentials using *CURRENT that I
am overlooking?

Is this question clear enough, or would more information be helpful.
Thanks for all your help!
