Hi Ronald,
Thanks for your reply.
Yes I called the create key method. Given below are list of method calls i used
objKey.createKey(objsrk, null);
objKey.loadKey(objsrk);
objKey.getAttribData(TcTssConstants.TSS_TSPATTRIB_RSAKEY_INFO, TcTssConstants.TSS_TSPATTRIB_KEYINFO_RSA_MODULUS);
objKey.getAttribData(TcTssConstants.TSS_TSPATTRIB_RSAKEY_INFO, TcTssConstants.TSS_TSPATTRIB_KEYINFO_RSA_EXPONENT);
where objKey is rsa key object of type migratable | legacy and objsrk is the wrapping key.
As said previously in trailing mail i am able to extract public key and modulus but failed to extract only rsa exponent
Regards
Ravi

Hi Ravi,
Did you actually call the createKey() method or did you just create the Java object?
