Chandrabhaga Urban Bank has three systems that must speak to one another: a deposit system written in C running upon a Unix server, a loan system written in Java running upon a second server, and a reporting system running upon Windows. The architect has ruled out writing point-to-point interfaces between them and has asked instead for a layer of software standing between the operating system and the applications, which will let a program on one machine invoke an operation upon an object residing on another as though it were local, hiding the di erences of language, of hardware and of operating system behind an interface de nition and a broker that dispatches the request. Among the following, the one that is a middleware technology of that kind is:

1. AHTTP, the Hypertext Transfer Protocol
2. BXML, the Extensible Markup Language
3. CEthernet, as speci ed in IEEE 802.3
4. DSMTP, the Simple Mail Transfer Protocol
5. ECORBA, the Common Object Request Broker ArchitectureCorrect
