JDBC Compatibility with ASE 15.7

Hi, Colleagues.

I wonder about jdbc compatibility with ASE 15.7.

My customer wants to know about it.

Customer is using jconn3.jar with ASE 15.0.3 ESD#4.2 on Sun sparc.
But CT is going to upgrade ASE 15.7 SP122. (ebf 22774)

So, CT wondering a compatibility between jconn3.jar and ASE 15.7 SP122.

I have checked it as follow link.

Sybase White Paper: Basic JDBC Connectivity for Sybase Databases, Supplement for Sybase Partner Certification Reports, u…

But, I couldn't find any information exactly.

If someone knows about that please let me know.

In addition, is there any restriction of using 15.0.3 features on ASE 15.7 SP122?

Thanks in advance.
