genJava jars with EnterpriseOne adapter 8.94

Hi,
We are using the EnterpriseOne 6.2 adapter Fix1 on Solaris 2.9

We created jar files with the genJava script with our XE erp.

If I create an updated jar files, place it in Adapter genJava directory and bounce the adapter. It does not pick up the updated BSFNs in it. Why?

Please help.
Thanks.
