AS/400 Program Call

Hello,
        I have a program, that resides on a server and is called by serveral 
clients. Further one thread of this program calls programs on an AS/400 
that create a file, do some work, and returns to the java thread. My 
problem is this: I need to use the same file for all instances of the 
program calls on the AS/400 and I can not have more than 1 client 
calling the AS/400 programs at once as the file can not be overwritten 
by client 2 while client 1 is running the AS/400 programs. I have 
syncronized the method of the thread but do not feel like this is 
sufficient. Does anyone have a suggestion. Thanks in advance.
