Server Smalltalk Guide


About this product or feature

Smalltalk Server enables you to write applications in a workstation environment that will ultimately run in a server environment.

Smalltalk Server provides you with a full-scale client-server environment; you can write and run applications using one encapsulated object-oriented technology.

The VisualAge Server Workbench feature contains a distributed object-oriented framework that you can use to develop client-server applications. The framework is called Server Smalltalk (SST) and is provided in Server, SST.

SST supports distributed object-oriented messaging on TCP/IP, HTTP, SMTP, and IMAP4. Further, SST permits distributed Smalltalk messaging and Smalltalk interoperability with Java RMI and IIOP.

SST attempts to integrate with external services seamlessly without affecting expected or standard behavior. Internally, SST is a framework of components, each representing major distributed system elements, such as middleware interfaces. These components are composed to build a distributed object architecture which is in turn used to build end-user applications.

SST also attempts to integrate existing standard services, capabilities, and mechanisms rather than re-implement or invent new ones. Thus, many of the components used in SST may already be familiar to you.

SST is supported on OS/2, Windows NT, AIX, Sun Solaris, and Windows 98/95 (client only).

This book covers SST in two main topics:
