convertToMultiKey appears in two places with different signatures. We were able to fix this by removing the SubjectHelper class file.

$ javap -classpath grouper.jar edu.internet2.middleware.grouper.subj.SubjectHelper
Compiled from "SubjectHelper.java"
public class edu.internet2.middleware.grouper.subj.SubjectHelper {
  public edu.internet2.middleware.grouper.subj.SubjectHelper();
  public static java.lang.String sourcesToIdsString(java.util.Collection<edu.internet2.middleware.subject.Source>);
  public static org.apache.commons.collections.keyvalue.MultiKey convertToMultiKey(edu.internet2.middleware.subject.Subject);


$ javap -classpath /var/tomcat/grouperdev/webapps/grouper-ws/WEB-INF/classes/ edu.internet2.middleware.grouper.subj.SubjectHelper
Compiled from "SubjectHelper.java"
public class edu.internet2.middleware.grouper.subj.SubjectHelper {
  public edu.internet2.middleware.grouper.subj.SubjectHelper();
  public static java.lang.String sourcesToIdsString(java.util.Collection<edu.internet2.middleware.subject.Source>);
  public static edu.internet2.middleware.grouperClient.collections.MultiKey convertToMultiKey(edu.internet2.middleware.subject.Subject);


$ rm SubjectHelper\$1.class
$ rm SubjectHelper.class

Hello,

Just ran into the same issue (2.4 latest patches). I think the problem came from this commit and the modification of the import for MultiKey class.
Any solution ?

Thanks !

Regards,
Yoann.

I am using Grouper 2.4 with all recent patches installed. I get an error when I try to call the GetSubjects method using the Web Service.

java.lang.NoSuchMethodError: edu.internet2.middleware.grouper.subj.SubjectHelper.convertToMultiKey(Ledu/internet2/middleware/subject/Subject;)Lorg/apache/commons/collections/keyvalue/MultiKey;

I see this source file contains getSubjects() which calls convertToMultiKey(subject)
grouper-ws/grouper-ws/src/grouper-ws/edu/internet2/middleware/grouper/ws/GrouperServiceLogic.java

I see that convertToMultiKey() is here in the Tomcat directory
$ grep convertToMultiKey /var/tomcat/grouperdev/webapps/grouper-ws/WEB-INF/classes/edu/internet2/middleware/grouper/subj/SubjectHelper.java
  public static MultiKey convertToMultiKey(Subject subject) {

so it is strange that the method is not found by the Web Service. Any advice would be appreciated.
