According to this recent CNET report, "Google, BEA in enterprise portal mashup talks", the two companies are in partnership talks on a new initiative to deliver tools for enterprise developers. The tools would allow creation of composite, mashup-style applications using BEA's WebLogic Portal along with Google APIs like their popular maps API. The key piece for BEA is their not-yet-released "Adrenaline" technology that integrates sites outside the portal framework but still manages them within the portal context.
Regardless of how this one works-out, these sorts of deals are another step along the enterprise path as open Internet mashup techniques begin making their way behind the firewall. Expect to see a lot more of this from established enterprise tool vendors in the not too distant future.
