plz i will also like to know the logic behind this too
thanks..
Once downloaded the project with all its jar files, I do not find where these packages are:
import com.digitalpersona.uareu.Engine;
import com.digitalpersona.uareu.Engine.Candidate;
import com.digitalpersona.uareu.Fid;
import com.digitalpersona.uareu.Fmd;
import com.digitalpersona.uareu.Fmd.Format;
import com.digitalpersona.uareu.Reader;
import com.digitalpersona.uareu.UareUException;
import com.digitalpersona.uareu.UareUGlobal;
Please, can someone help me?
CarlesFranquesa.
Do you import the jar file dpotapi?
it is necessary to execute all digitalPerson relative applications.

Thank You so much manniru..
this is what im looking for a long time.
i run the program with little editing and success.
Best of Luck.
another question, please
I made the DB with MYSQL. the data type for finger template I made is Blob.
I need to store it in binary.
can you advise me, please
what function i will convert it to binary? and then also verified it in binary.?
Please, can you kindly upload a read me file showing the data and their respective types being passed to the database

//please sir what sdk did you use for this is it flexcode or ...?
hi please i am trying to do this fingerprint stuff using javafx and i have been running into some problems and i need help with it.
i have been reading on this trying to graps the logic behind makig such type of application and i will need help to full understand it.
plz i will like to know which sdk you used for this and how i can get it.
am seeing you using various import eg import com.digitalpersona.onetouch.processing.DPFPEnrollment;
how did you come about them is it part of the sdk?
