Obtaining ldap query's results count

[amos_s12]

Hello,

    Following to my previous topic, I've got an answer that I can use
the method
$mesg->count() in order to obtain the query's result count.

    I would like to know, how can I join this method in the following
code:
 ...
String dirStr = <certain value>
searchControls.setReturningObjFlag(false);
searchControls.setSearchScope(SearchControls.SUBTREE_SCOPE);
searchControls.setReturningAttributes(retAtt);
searchControls.setCountLimit(countLimit_No_Limit);

StringBuffer filter = new  StringBuffer();

filter.append("(&(objectclass=<a certain object class>)");

filter.append("(");
filter.append("certain field=");
filter.append(<certain value>);
filter.append("))");


NamingEnumeration answer = context.search(dirStr, filter.toString(),
searchControls);


if (!answer.hasMore()) {
    return 0l;
}

int resultsNumbert = 0;
while (answer.hasMoreElements()) {
    SearchResult searchResult = (SearchResult)answer.next();
    resultsNumbert++;
}
...
return resultsNumbert;


Here I count the results myself . What I would like  to know,  is how
to use the method :
$mesg->count() in order to get the results count

Thank you in advance for your answer
