There is no difference from a Java application perspective. The only noticeable difference is that with a 64-bit JVM you can allocate larger heaps because you are not constrained to a 4GB memory address. Another issue would be if your Java app makes use of any DLLs (or shared libraries) - you would need a 32-bit version of the DLL to run with a 32-bit JVM and a 64-bit version of the DLL to run with a 64-bit JVM.

I typically run the same apps on a 64-bit JVM and a 32-bit JVM without any issues.

If you want to track down the connection issue, you might want to use the tools SQL Server provides to monitor database activity. Perhaps there is a query that is taking too long.
