[jboss-jira] [JBoss JIRA] Created: (JBRULES-1180) java.lang.ClassCastException: org.drools.reteoo.RightInputAdapterNode
java.lang.ClassCastException: org.drools.reteoo.RightInputAdapterNode
---------------------------------------------------------------------
Key: JBRULES-1180
URL: http://jira.jboss.com/jira/browse/JBRULES-1180
Project: JBoss Rules
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 4.0.1
Environment: JDK 1.5, Mac OS X 10.4
Reporter: Markus Reitz
Assigned To: Mark Proctor
Using the rules
package test
import java.awt.*;
rule "A"
when
exists(x : Dimension(x_height : height) and
y : Dimension(this!=x, height!=x_height))
then
System.out.println("A");
end
rule "B"
when
not(exists(x : Dimension(x_height : height) and
y : Dimension(this!=x, height!=x_height)))
then
System.out.println("B");
end
as input for the following program (java DroolsTest <name of rule file>)
import org.drools.*;
import org.drools.compiler.*;
import org.drools.rule.Package;
import java.io.*;
import java.awt.*;
public class DroolsTest {
private RuleBase rules;
private StatefulSession memory;
public DroolsTest(File file) throws Exception {
rules =RuleBaseFactory.newRuleBase();
memory=rules.newStatefulSession();
rules.addPackage(loadPackage(file));
}
protected Package loadPackage(File file) throws IOException {
FileInputStream stream=null;
try {
stream=new FileInputStream(file);
return(loadPackage(stream));
}
finally {
if (stream!=null)
stream.close();
}
}
protected Package loadPackage(InputStream stream) throws IOException {
try {
PackageBuilder builder=new PackageBuilder();
builder.addPackageFromDrl(new InputStreamReader(stream));
return(builder.getPackage());
}
catch(Exception ex) {
throw new IOException();
}
}
public StatefulSession getSession() {
return(memory);
}
public static void main(String ... args) {
try {
DroolsTest test=new DroolsTest(new File(args[0]));
System.out.println("Inserting ...");
test.getSession().insert(new Dimension(1,2));
test.getSession().insert(new Dimension(2,3));
test.getSession().insert(new Dimension(4,2));
System.out.println("Done.");
System.out.println("Firing rules ...");
test.getSession().fireAllRules();
System.out.println("Done.");
}
catch (Exception ex) {
ex.printStackTrace();
}
}
}
leads to
