         Key: JIBX-107
         URL: http://jira.codehaus.org/browse/JIBX-107
     Project: JiBX
        Type: Bug

  Components: core  
    Versions: JiBX 1.0.1    
 Environment: Windows XP 
Eclipse Ant Build
    Reporter: Jayaram  C S


I am using the following mapping file 

<binding>
           <mapping  name="RulesDescr" class="org.drools.lang.descr.RuleDescr">
          <value name="name" style="attribute"   field="name"/>
          <value name="documentation" field="documentation" usage="optional" />
          <value name="consequence" field="consequence"  />
          <value name="className" field="className" usage="optional" />
          <structure name="lhs" type="org.drools.lang.descr.AndDescr" >
                         <collection field="descrs"  type="java.util.ArrayList">
                            <structure name="Eval" 
type="org.drools.lang.descr.EvalDescr"  >
                                <value name="text" field="text"/>
                                
                        </structure>
                     </collection>
                  </structure>
     </mapping > 

</binding>

It shows the below exception and halts. I have tried various combinations but 
in vain .
