Java Interface (Full Version)

Setting Up Java

The Java interface is in the runtime/java subdirectory. Before you can run this program, you must set-up the Amzi! Logic Server.

You can do this by either:

• Put the knowledgewright4/workshop directory on your PATH environment variable

  or

• Copy amzi.cfg, amzi.dll, aosutils.lsx, aodbc.lsx to the directory containing the Java code.

Then you need to:

• Copy the jig reasoning engine (.xpl) file from the workshop/jigs subdirectory. For the basic jig, this is basic.xpl, for the support jig, this is support.xpl, etc.
• Copy the knowledgebase (.kb) file you want to run to the directory containing the Java code.
• Put the Borland libraries in workshop/lib on your CLASSPATH, for example:
  

   CLASSPATH= /knowledgewright4/workshop/lib/dbswing.jar;/knowledgewright4/workshop/lib/dx.jar

This will let you run the sample as provided. In order to write your own Java programs, you need to install the Amzi! Logic Server Java Classes. They are located in the 'amzi/ls' directory tree under runtime/java. You can simply add this to your CLASSPATH environment variable:

CLASSPATH=/knowledgewright4/runtime/java;/knowledgewright4/workshop/lib/dbswing.jar;/knowledgewright4/workshop/lib/dx.jar;...

Setting Your Path and Classpath Under Windows

To change your PATH environment variable you need to open the Control Panel and then open System. One on of the tabs you will find a button labelled 'Environment Variables'. Press it and modify your PATH according to the instructions above.

You can use the same method to change your CLASSPATH. Alternatively, some development environments (like Borland's JBuilder) let you specify a CLASSPATH in your Java Project. Finally, you can use the -cp flag on the Java Compiler, javac, to specify a CLASSPATH for each compilation.
