The Pro edition can be used to host any number of the developed applications on any Web server of your choice.

How is CruXpert different from other similar tools?

Knowledge Based Applications developed using CruXpert are compiled into highly efficient and compact Java class files. This increases the speed of CruXpert applications as they run directly on the Java Virtual Machine(Java VM) without being interpreted. This offers a significant advantage while developing time critical embedded applications. Moreover, with the advent of Java Chips, CruXpert can be used to develop complex, rule based applications for embedded controllers. To make this possible Ultrexx Corporation is releasing CruXpert API that provides the class library and API documentation for developing embedded applications.

Is there a way to visually build CruXpert applications without programming?

Yes, it is possible to build applications using the visual tool CruXpert Graph Builder. This is a separate tool that works with CruXpert Version 2.0 to add visual development capability. With this tool, knowledge bases can be developed in minutes by visually creating the consultation sequence through a graph and subsequently converting this graph into Java classes, ready for publishing on to the server. In addition, this tool facilitates the saving of these knowledge graphs as CKRL program for those interested in enhancing the application with other features of the language. Please make sure you have installed CruXpert prior to the installation of this tool.

Why do I require Java Development Kit to build CruXpert applications?

CruXpert has three components, namely,

1. CruXpert Knowledge Representation Language(CKRL) compiler
2. Inference engine
3. Target Application Interface Template(TRAIT)

The CKRL compiler converts the knowledge base into a JAVA program. In order for the knowledge base to be integrated with the Inference engine and TRAIT, the Java program has to be compiled into a portable format called 'Byte code' which will be created through a Java compiler (like the one available in JDK 1.0.2).

How do I install Java Development Kit 1.0.2 on my computer?

There is no charge for this download. Please follow the directions below to correctly download the program:

1. Connect to the Internet
2. Go to the JavaSoft home page----(http://www.javasoft.com)

21. Open the FILE menu and choose save. Then close the DOS editor.
22. To have the Autoexec.bat changes take effect, please restart the computer.

How do I build a knowledge base and test it using CruXpert?

Currently there are two ways to build a knowledge base. They are

1. Using the CruXpert Application Builder(CAB) that is bundled with the product distribution
2. Using conventional text editors like Notepad, Edit etc.

To develop using CAB, go through the CAB User's Guide which is accessible through the Help->Help Topics on the CAB main menu. There are some advantages of developing applications using this method. You can develop, compile and run the knowledge base application without leaving the CAB. CAB even has a feature to publish the knowledge base and its support files on a WEB server of your choice.

To develop and test the knowledge base using other editors requires you to be familiar with that editor. If you want to create the Knowledge Base using an editor available on Windows 95 use the Notepad. You could invoke the Notepad through Start->Accessories->Notepad starting from the Windows' Task Bar. Please refer to the CruXpert User's Guide for a step by step procedure.

Why doesn't CAB run on platforms other than Windows 95?

CruXpert Application Builder (CAB) is a Windows 95 application developed using Visual C++ 5.0 and hence it does not run on platforms other than Windows 95.
