[rules-users] <pattern /> tag is not working in rule file

[prateek.katiyar at wipro.com]

Hello all
 
I am using Drools 4.0.3
I am using a .xml rule file in my application in which I am validating
the user entered data through my rule file.
When I am not using <pattern /> tag in my rule file then it is working
fine but when I use it ,the rules are not firing even it is not showing
any exception also.
For your reference I am coping my rule file below :
 
<?xml version="1.0" encoding="UTF-8" ?> 
    <package xmlns="http://drools.org/drools-4.0"
xmlns:xs="http://www.w3.org/2001/XMLSchema-instance" name="jbossrules"
xs:schemaLocation="http://drools.org/drools-4.0 drools-4.0.xsd">
      <import name="com.wipro.evalidator.response.bean.ResponseBean" /> 
      <global identifier="response"
type="com.wipro.evalidator.response.bean.ResponseBean" /> 
      <import name="java.lang.*" /> 
      <import name="com.wipro.airline.SearchBean" /> 
     <rule name="rule1">
              <rule-attribute name="agenda-group" value="AirlineApp" /> 
              <rule-attribute name="activation-group"
value="activation_1195126928297" /> 
              <lhs>
                  <pattern identifier="searchbean"
object-type="com.wipro.airline.SearchBean" /> 
                  <eval>true</eval> 
         </lhs>
             <rhs>
                    System.out.println("date is not
valid.");response.setStatus("failure");response.setSubStatus("date_notva
lid");
              </rhs> 
  </rule>
</package>
 
 
If <pattern /> tag is not allowed here then how can we use SearchBean
fields in the lhs part of the rule.
Any help will be appreciated.
