The app should use both processors by default assuming that it is multi-threaded. If the app is single threaded it will only use one CPU at a time.
In order to use more than 2 Gigs of RAM the java app will need to support AWE. If it doesn't (you'll have to check with the folks in the java forum to see if JAVA can address more than 2GB of RAM) then you won't be able to.
With reguard to SQL Server it will automatically use both CPUs. If you have Enterprise Edition you can enable AWE within SQL Server (by using the Enterprise Manager or the sp_configure procedure). You will also need to use the /PAE and /3GB switches in the boot.ini and reboot (if you haven't already done so).

Note: All questions are in regards to Windows Server 2003, Enterprise Edition.
Are the /PAE and /3GB switches a viable option in a 64-bit OS, or do they only pertain to a 32-bit system?
The only time to use both the /PAE switch and /3GB switch, in conjunction, is when the system is using less than 16 GB of memory, correct?
What are some practical situation for using only the /PAE switch, or only the /3GB switch?
What is the proper scenario for using the /nolowmem switch in the Boot.ini file?

AWE only applies to x86. It doesn't apply to x64.
Here is the MSKB on using more than 2 Gigs
