Sun's solution was based on work in their [[Spring operating system]], which used intercommunicating objects for almost all programming tasks. Modifying this to work under a 'traditional' Unix like Solaris was not all that difficult, although Unix makes the assumption that all programs run locally, and an interface for remote access had to be added. For this, DOE added an [[object request broker]] (ORB) that ran on the backoffice servers, listening for DOE requests and handing them off to the proper program to be handled. During development, CORBA became a key [[buzzword]] in the industry. This prompted a delay while the ORB was re-engineered for CORBA support. Under the CORBA model, different objects, like those from DOE or SOM, would be able to interact by sharing a common interface.
A bigger problem for Sun is that they had no integrated desktop object programming solution. Although [[C++]] object libraries were becoming common on some platforms, their own [[SunOS]] (later known as [[Solaris Operating System|Solaris]]) operating system and associated [[SunView]] and [[X Window System|X]] window systems were 'plain C' based, while [[NeWS]] was based on a network extensible object oriented dialect of PostScript. In order to supply a comprehensive and flexible object programming solution, Sun turned to NeXT and the two developed [[OpenStep]]. The idea was to have OpenStep programs calling DOE objects on Sun servers, providing a backoffice-to-frontoffice solution on Sun machines. OpenStep was not released until 1993, further delaying the project.
By the time DOE, now known as NEO, was released in 1995,<ref>{{cite press release
