Entera allows developers to link client systems, databases, and legacy software into distributed applications.
Version 4 adds support for Java and Borland's Delphi programming tool, giving developers additional choices in the language used to build systems, Borland said. The software already supported development using C and C++, Cobol, PowerBuilder, and Visual Basic.
The middleware currently uses a remote procedure call (RPC) mechanism for communication between applications. Borland said a future release will support its VisiBroker object request broker and its MIDAS architecture. That will allow Entera to work with CORBA- (common object request broker architecture) and COM- (component object model) based applications.
Entera 4 also works with Borland's recently announced AppCenter application management tool for administering distributed systems, the company said. Borland has also improved security options in the new release.
No pricing was announced.
