i created role following rdn:

no didn't. dn (distinguished name), not rdn (relative distinguished name). rdn part of erglobalid=3224285689051620393.

i deleted above role

good you.

now above rdn not exists in ldap.

the above dn doesn't exist in ldap.

i want check whether exists or not in ldap?

it doesn't. deleted it. if delete had failed have thrown exception. if didn't fail, it's deleted, doesn't exist.

is there method such in this?

yes, there search() , lookup() methods.

i checked search() , lookup() methods, these methods throwing exceptions ... because of according requirement of application have write code in catch block

correct.

which not ideal

which way apis designed. bad luck. there nothing can it. nb search() doesn't throw exception if nothing matches: returns empty enumeration of searchresult.

i imagine you're really asking checking existence before deletion. bad idea: causes 2 lookups @ server instead of one, , twice network traffic, or more ... , suffers timing window problem: might exist when test , not exist when delete, or, worse, might not exist when test exist when delete, or when have deleted. don't this. don't think this. deletion atomic operation fail if entry doesn't exist. want.
