Hi Amarjit,
If i'm remember correctly, deployoment file on Java are written to /usr/sap/SID/JC**/SDM, you'll see all the deployment files once you navigate to this file system.
Once Java system is start up, i believe the bootstrap will read the info from the file system and sync it to the datase. That's the reason why when we need Java system migration, we need to export both Java DB and the file system.
my 2 cents worth.
Cheers,
Nicholas Chang
