VisualAge Java-RMI-Smalltalk The ATM Sample from A to Z

Remote Method Invocation (RMI) is a great enabler for distributed objects on the Internet and intranet. RMI is also well suited for enabling communication between Java and Smalltalk. Client software - either applets or servlets - can easily talk to Smalltalk servers and vice versa. The RMI implementation in Server Smalltalk (SST) makes legacy VisualAge Smalltalk Enterprise the server of choice for Internet and intranet business.

VisualAge Smalltalk Enterprise enables fast and reliable application development and delivery for workstations and servers. Java, widely used for servlets on Web servers and for downloaded applets at runtime, is the perfect client-oriented component for e-Business applications distributed world wide. As the bridge RMI gives you the choice of combining the strength of both components, enables interoperability between your Java and Smalltalk world, and lets you individually choose the appropriate tool for your business applications.

RMI, which became available in Smalltalk with Version 4.5, enables you to connect in an object-oriented way - and on a relatively high level - client and server objects. RMI is practically transparent for application developers, makes it easy to let the objects live where their gravity pounds, and is much easier to setup than a full-fledged object request broker (ORB).

The chapters of this book describe the steps of the ATM sample application development from A to Z: from creating the business model to developing the user interface and coding details in VisualAge for Java and VisualAge Smalltalk. The hands-on exercised in this book will make you a VisualAge for Java-RMI-VisualAge Smalltalk Server developer, ready to accept todayÆs application development challenges for the Web.
