How to check if a certain attribute exists in LDAP? (using AttributesMapper)

[czaveri]

Yet another basic question: (don't even know if it belongs here. Please feel free to delete and let me know if it doesn't).

I am trying to figure out how to check whether a certain Attribute exists in LDAP using AttributesMapper. I glanced at http://java.sun.com/j2se/1.5.0/docs/...ttributes.html but the only method that I see there with a boolean result is isCaseIgnored() which is not what I need.

I am getting the attributes, using the following:

attrs.get("employeeName").get()

where, attrs is a reference to an object of type Attributes.

I wish to check if "employeeName" attribute exists, and only if it exists, I want to set a variable with its value.

Thanks in advance for your help!

I came across DirContextAdapter having the boolean test

protected  boolean 	exists(Attribute attr)
          Checks if an entry has a specific attribute.

But since I am using AttributesMapper I assume, that is not an option (?)

The general recommendation is to use ContextMapper anyway - manually fiddling with Attributes is tedious and error prone.
