Subject: About Quotes in Xml file



Hi
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
Prateek
