Thanks for your reply.

I have a field "m_rfqId" in one of my JavaBean "RFQBean" and i want to implement a rule on this field as

rule "Check_NotNullof_rfqId"

agenda-group "Check"

when

RFQBean((m_rfqId == null)||(m_rfqId == ""))

then

response.setStatus("For RFQ Bean: The value of m_rfqId is null.");

System.out.println(response.getStatus());

end

Now when i used XmlDumper for the .xml format of this rule then i got the following syntax:

<rule name="Check_NotNullof_rfqId">

<rule-attribute name="agenda-group" value="Check" />

<lhs><pattern object-type="RFQBean" >

<or-constraint-connective><field-constraint field-name="m_rfqId">

<literal-restriction evaluator="==" value="null" />

</field-constraint>

<field-constraint field-name="m_rfqId">

<literal-restriction evaluator="==" value="" />

</field-constraint>

</or-constraint-connective>

</pattern>

</lhs><rhs> response.setStatus("For RFQ Bean: The value of m_rfqId is null.");

System.out.println(response.getStatus());

</rhs>

</rule>

When i tried with this .xml format then i got the follwing error:

org.drools.compiler.DroolsParserException: org.xml.sax.SAXParseException: <literal-restriction> requires an 'value' attribute

at org.drools.compiler.PackageBuilder.addPackageFromXml(PackageBuilder.java:177)

at com.wipro.rfq.report.bean.Validator.readRule(Validator.java:90)

at com.wipro.rfq.report.bean.Validator.main(Validator.java:47)

Now please tell me that how can i achieve my requirement?

Have a great day.

With Regards
