Javascript example that works with attribute-resolver.xml and Java 8

[Eric Wedaa]

Just in case somebody else needs help writing a script for Shib IDPV3 with Java 8...

I had to create a "firstname" field based off of "cn" (commonname in LDAP)

What follows is the script that works in my attribute-resolver.xml file.  It took waaay too long to get this to work so maybe this is helpful to somebody else

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

         <Script><![CDATA[

              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>
