I want to log, at the application level, database connections that are hanging.
I am not sure this is possible, if so, help me on this issue.

If a connection actually “hangs”, it’s often a deadlock. The database is the best place to diagnose and log these problems in detail.
However, I know that the MS SQL Server driver will throw a pretty specific exception after a deadlock victim is chosen and from my (much more limited) experience with Java, I imagine the Sybase driver does the same. You could trap that exception from your application. Even if it’s a general exception, you might examine a stack trace or description and ascertain that it pertained to a lock issue.
