Exception in thread "main" java.lang.Error: Unable to find unambiguously defined class

Hi,

I have a simple rule that references a "Process" fact:-

package com.ford.nges.jboss.rules

import com.ford.nges.om.Constants
import com.ford.nges.om.Component
import com.ford.nges.om.ResourceEntry
import com.ford.nges.om.Process
import com.ford.nges.om.Machine

rule "A rule"
when
p:Process( )
then
System.out.println(p.toString());
end

However I receive the following error on builder.addPackageFromDrl(new InputStreamReader(Main.class.getResourceAsStream("rules.drl"))); even though I have an import statement.

Exception in thread "main" java.lang.Error: Unable to find unambiguously defined class 'Process', candidates are: [java.lang.Process, com.ford.nges.om.Process]

        at org.drools.compiler.PackageBuilder.addPackageFromDrl(Unknown Source)
        at com.ford.nges.Main.main(Main.java:43)

If "Process" is referred to in the RHS or the Class name is not Process I don't get the error.

Any thoughts?

With kind regards,
