Java API to find group members?

Question

I need to find a way to list all the members of a group.
There're only two similar methods in the oracle OID java API. Group.isMember() and Util.getGroupMemberShip().
Is there something like Group.getGroupMembers(), or Util.getGroupMembers()?
If not, do I have to query the OID myself? Thanks!

Hi,
You can do it using JNDI - e.g: I have posted a code snippet here that shows my isGroupMember method. The method checks if a user belongs to a Group
* The method isMemberInGroup checks if a user is a member of a group. The
* method relies on the Context provided by the calling method.
* @throws java.lang.Exception
* @throws javax.naming.NamingException
* @return bIsMemberInGroup true, if the user is a member of the group.
* @param objDirContext the DirContext provided by the calling method.
* @param strGroupDN the DN of the Group.
* @param strMemberDN the DN of the Member.
public boolean isMemberInGroup(String strMemberDN,
String strGroupDN,
DirContext objDirContext)
throws NamingException, Exception
SearchControls objSearchControls = new SearchControls();
String[] strAttributes = new String[]{};
String strFilter = null;
boolean bIsMemberInGroup          = false;
NamingEnumeration objNamingEnumeration;
try
objSearchControls.setReturningAttributes(strAttributes);
objSearchControls.setSearchScope(SearchControls.OBJECT_SCOPE);
strFilter = "(&(uniquemember="+strMemberDN+")(objectclass=groupOfUniqueNames))";
objNamingEnumeration = objDirContext.search(strGroupDN, strFilter, objSearchControls);
bIsMemberInGroup = objNamingEnumeration.hasMore();
catch(NamingException objNamingException)
ExceptionHandler.handle(objNamingException);
catch(Exception objException)
ExceptionHandler.handle(objException);
return bIsMemberInGroup;
}// end of isMemberInGroup method
You can find many such examples on popular Java Websites....
