Trying to empty file using > but the file size increasing when next append

AIX 5.3 / KSH

I have a Java application which creates a log file a.log. I have a KSH script which does the following action

Code:
cp a.log /directory2/b.log
> a.log
After this the file size goes to 0 as per "ls -l"

Then next time when the application writes into this file, the file size is goes to the previous before the ">" operation happened.

I tried the Code in a different style:
Code:
cp a.log /directory2/b.log
cp /dev/null a.log
No change. What is the best way to do this?

***NOTE: I cannot use rm -f/touch method for cleaning up the log file because it requires a restart of the application.
