How to add third-party jar in CRM ISA application?

Hello SDN!

I need to add third-party jar in CRM ISA application. I know how to add such jars in common case and for local DCs. But for CRM I can't determine which DC should contain this third-party jar.

Please tell me ASAP which DC (e.g. crm/isa/home/ext) I should use.

Help will be appreciated.

Regards, Lev.
