如何从java类调用guvnor规则

Question

我想从简单的java文件中调用guvnor规则。但我正面临着一些问题。 我正在使用jboss7进行部署。任何人都告诉我，如果我错过任何事情。

我的drl规则

package com.rule;

import com.rule.Rule1Bean;
rule "r1"

when 
    $s : Rule1Bean(true)

then

    $s.setB("b");
    System.out.println("finished" );
end

我的bean文件

package com.rule;

public class Rule1Bean {


    public Rule1Bean()
    {

    }




    public Rule1Bean(String a) {

        this.a = a;

    }




    private String a;
    private String b;
    public String getA() {
        return a;
    }
    public void setA(String a) {
        this.a = a;
    }
    public String getB() {
        return b;
    }
    public void setB(String b) {
        this.b = b;
        System.out.println("b="+b);
    }




}
