Upgrading to IDPV3, problems converting importPackage routines

[Eric Wedaa]

All

  I am working on upgrading to IDP V3 and Java 1.8 and have hit a brickwall with importPackage no longer working.  I have seen the webpage at https://wiki.shibboleth.net/confluence/display/SHIB2/IdPJava1.8 and tried (as best  as I can) to follow the instructions but I am still getting an error 

 ERROR [edu.internet2.middleware.shibboleth.common.attribute.resolver.provider.attributeDefinition.ScriptedAttributeDefinition:130] - 148.100.144.177 - firstname produced a null attribute

If anybody can help I would greatly appreciate it.  (I'm sure it's something simple I'm missing, but I'm not a big Java person.)

Modified to match what the webpage says  code sample below:

        <resolver:AttributeDefinition id="firstname" xsi:type="Script"
        xmlns="urn:mace:shibboleth:2.0:resolver:ad" sourceAttributeID="cn">
                 <resolver:Dependency ref="myLDAP" />
                 <resolver:AttributeEncoder xsi:type="SAML2String"
        xmlns="urn:mace:shibboleth:2.0:attribute:encoder" name="firstname" />

         <Script><![CDATA[
              var BasicAttribute = Java.type("edu.internet2.middleware.shibboleth.common.attribute.provider.BasicAttribute");
              firstname = new BasicAttribute("firstname");

              var cn;

              if (cn != null && cn.getValues().size() > 0) {
                  gnvalue = cn.getValues().get(0); 
                  result=gnvalue.split(" ");
                  gnvalue = result[0];
              } else {
                  gnvalue = "-";
              }

              firstname.getValues().add(gnvalue);
          ]]></Script>
    </resolver:AttributeDefinition>

thanks lots!
