This release of Verastream Host Integrator (VHI) offers enhancements to existing VHI features as well as the Web Builder, an optional tool that enables you to quickly and easily generate and deploy a procedure-based web application or a component interface, such as a web service or JavaBeans, based on the table layer of a host application model created with the Design Tool. Additionally, the Web Builder can generate screen-based web applications based on a host application or the model layer of a host application model created with the Design Tool.

If you are upgrading from Verastream Host Integrator version 4.5 to version 5.0, check the technical support site. To view the new features that became available in the VHI 4.5 release, click here.

Web Builder Features

VHI provides several web project options for you when you decide to use the Web Builder. After modeling your host application, you can choose to create a web application or create a component interface using your existing host application model as a template.

Creating a Web Application

VHI offers the following two types of web applications that can be generated from the Web Builder:

Screen-based web application - The screen-based web application option enables you to either (1) create a web application with a terminal web interface that displays your host screens or (2) create a web application with a standard web interface that only displays the model objects that you've designed in the your host application model. To build a screen-based web application, select the Screen-based option in the New Project dialog box.
Procedure-based web application - The procedure-based web application option enables you to generate a web application that provides a web interface for table procedures defined in VHI models. To build a procedure-based web application, select the Procedure-based option in the New Project dialog box.

Creating a Component Interface

A component interface generates a set of support files for creating your own web application that directly accesses the procedures, entities, attributes, or operations in a host application model. VHI offers the following two types of component interfaces that can be generated from the Web Builder:

JavaBeans - The JavaBeans option enables you to generate JavaBeans if you want to access a host application through your own Java application. Click here for more information about JavaBean generation.
Web service - The Web service option enables you to generate a web service if you want to access a host application through your own Java application.

Enhancements to Existing Verastream Host Integrator Features

New Java API for Modifying Model Variable Lists

A new set of Java interfaces are available that permit a client application possessing VHI Administrator credentials to examine and to modify the contents of the model variable lists on any single VHI server or for all servers within a VHI domain. To view this new API, go to the Host Integrator folder on the Start menu, then click Help > API-JavaDoc to open the Java API documentation. Under Packages, click com.wrq.vhi.sconfig to view the new API for editing model variable lists. Click here for more information about managing model variable lists.

New Java API for Supporting a Rejuvenation Session

A new Java API has been added to the Java connector to support the rejuvenation feature of the Web Builder. On the Start menu, click Programs > Verastream Host Integrator > Help > API-JavaDoc to open the Java API documentation. Under Packages, click com.wrq.apptrieve.appconn. To view the new API, click AppConnRejuvenationSession under Class Summary.
