Moving from Java 1.5 to Java 1.6

Hi

We have an application which uses postgresql 7.4.5.

Now when we moved to Java 1.6, we are seeing lots of jdbc driver related
compilation issues like shown at end of this email.

Question is can we just only upgrade jdbc driver alone or its better to
move completely to a new postgres version. ?

Are there any docs that explain about how to migrate ?

thanks
