Thanks Anurag for the quick response.
From the details mentioned on certmanager.net/sun, the certificate was mailed on Mar1 as shown:
Fulfillment Mar 1, 2010 5035839 Sun Certified Programmer for the Java Platform, Standard Edition 6: Mailed
Fulfillment Feb 28, 2010 5035839 Sun Certified Programmer for the Java Platform, Standard Edition 6: Processed
Fulfillment Feb 24, 2010 5035839 Sun Certified Programmer for the Java Platform, Standard Edition 6: Newly Created
But till now I did not get my certificate.
Is there any other way of tracking the delay in this process?
Can I change my address and request for mailing it again?
