JessInJava

Relatively simple to do:

• Requires an instantiation of a JESS Engine and a Parser - jess.Rete and jess.Jesp.

	import jess.*;

	NullDisplay nd = new NullDisplay();

	// Create a Jess engine
	Rete rete = new Rete(nd);

	// Open the file test.clp
	FileInputStream? fis = new FileInputStream?("test.clp");

	// Create a parser for the file, telling it where to take input
	// from and which engine to send the results to
	Jesp j = new Jesp(fis, rete);
	try
	  {
		// parse and execute the code, without printing a prompt
		j.parse(false);
	  }
	catch (ReteException? re)
	  {
		// All Jess errors are reported as 'ReteException?'s.
		re.printStackTrace(nd.stderr());
		}

• It is also possible to call JESS functions and get results back (more complicated but covered in manual).
