The Java interface to the OpenROAD Server provides an easy way for programs written in Java to access 4GL business logic executed in an OpenROAD Server. Two interfaces provide support for 32-bit Java Servlet environments and 64-bit Java Servlet environments.

Third party Java-COM bridge products are available. The Java interface facilitates the connectivity between Java and OpenROAD by providing an interface that is simple, integrated with OpenROAD, and exposes a consistent external interface on all supported platforms.
