Correct binding and searching -- please look

Question

Given the following DIT:
edge.com (Domain)
|-- Subgroup 1(type Organizational Unit)
|-- MMC_Users (type Organizational Unit)
|-- Advisors (type Organizational Unit)
|-- Person One (type User)
|-- Person Two (type User)
|-- Q (type Organizational Unit)
|-- Person Three (type User)
|-- Person Four (type User)
|-- Person Five (type User)
|-- TNBT (type Organizational Unit)
|-- Person Six (type User)
|-- MSU (type Organizational Unit)
|-- Person Seven (type User)
How would I bind to find all the user names of people listed in a subgroups of MMC_Users? In other words, what user exist in the Advisors, Q, TNBT, and MSU groups.
I am using the following search code:
Hashtable oEnv =new HAshtable();
oEnv.put(javax.naming.Context.PROVIDER_URL, "ldap://bos-gc01:389/dn=edge,dn=com");
oEnv.put(Context.SECURITY_AUTHENTICATION, "simple");
oEnv.put(Context.SECURITY_PRINCIPAL, "user");
oEnv.put(Context.SECURITY_CREDENTIALS, "pasword");
DirContext oCTX = new InitialDirContext(oEnv);
SearchControls constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
System.out.println("asking for search results....");
results = oCTX.search("ou=Q,ou=MMC_Users","(uid=*)", constraints);
System.out.println("@@@ DOES IT GET HERE?");
while ((results != null) && results.hasMore())
System.out.println("never get here");
Any help would be greatly appreciated.
