pls what class should I use to send fingerprint image directly to database without using file upload?
I checked Google. suggestion there is that I should pass the image to InputStream but am having error on my IDE..pls how do I fix it? pls give me some codes..
thanks.

Compression it into a folder and create a referential link to it. It is the link you store in the database so as to make it easier to recall than uploading and downloading each time.

Boss, I don't understand..,,I have d image already...I have converted the image from long to string so I can change from string to binary stream...can fileinputstream take care of this? or in place of fileinputstrean, what should I use?..it on java

You need to give more information. Is this a web app or desktop application? How do you plan to use the fingerprint image? Is this a biometric application. This would help you determine the best way to store your finger print image. Ideally storing images as blob in a database is a BIG NO NO.....

ok Boss...thank u...am building a desktop application...it a biometric application.. finger print will b capture and shown on jlabel1, another 1 will b capture and shown on jlabel2 . if minutiae on jlabel = minutiae on jlabel2, then register the minutiae as fingerprint into database..
the fingerprint is declared as long,so I converted it to string. from string, we both know u have to convert it to binary stream... how do I do this?..

if using blob in database is a big no, how do I go abt it pls?

If you are asking how to convert the String to byte stream then you can do this:

String fingerprintstr= "frggteeeeeeeeeeeee";

String binarystream= "";
    char[] arraychar= fingerprintstr.toCharArray();

    for (int i = 0; i < arraychar.length; i++) {
        binarystream+= Integer.toBinaryString(arraychar[i]) + " ";
    }

Boss pls can u drop this on whatapp for me? my phone is small as such I can't read to d end...tanks...my no is 08022269656 or enefiokduke4info@gmail.com ...thanks

this what am seeing.. String fingerprintstr= "frggteeeeeee String binarystream= ""; char[] arraychar= fingerprintstr for (int i = 0; i < arraychar.le binarystream+= Integer.toBin it not complete ,as such I can understand it

Can you upload your code? I might be able to help you if I see what you've done. Or, if you can make your explanation clearer.

i couldn't upload it here...pls check ur WhatsApp.... thank u very much

Storing blob data in a database is a pretty bad idea. It just doesn't sound cool in terms of performance. Just store the image in a file system then store the link in a the database as text.
The fact that this is desktop app though.

Do you have my contact?

create a database to store the fingerprints
in msql
store.sql
user id
print1
create a table containing user ID and print
`userID` varchar( 32 ) NOT NULL ,
`print1` varbinary( 4000 ) DEFAULT NULL
look at the jar library and copy the the method
binary stream .

 private byte [] loadDataFile() {
 // TODO Auto-generated method stub
 JFileChooser fc = new JFileChooser( ne
 fc . showOpenDialog( this );
 if (fc . getSelectedFile() != null ) {
 InputStream input = null ;
 try {
 input = new BufferedInputStream( new F
 fc . getSelectedFile()));
 byte [] data = new byte[input . availa
 input . read(data, 0 , input . availab
 input . close();
 return data;
 } catch (FileNotFoundException e) {
 // TODO Auto-generated catch block
 e . printStackTrace();
 } catch (Exception e) {
 // TODO Auto-generated catch block
 JOptionPane . showMessageDialog( null
 }
 }
 return null ; 

in this case u have to make the prints to be stored in binary.

@proxy20, it means I will still use file upload which I don't want... all I need is capture d image ,n at d same time, send it to database...thank u for ur response but am not seeing everything text to end..paste it on my WhatsApp page...08022269656 or enefiokduke4info@gmail.com pls

I dont consider myself a java programmer cos since i learned it years back, I have not used it for to solve any important problem.

However conversion of data to bytes have the same algorithm in probably all languages.

In your case do this:

1.Write your data to a character array.
2.Write you data from the character array into a byte holder( or data structure) one char per time.
Thats it. Once your data is in a byte form it is equivalent to a database data type called blob which you can save to any database
using appropriate sql command.

If you, however, need to send you data over network, then use the appropriate stream/byte reader in your language.

@duke2017, the answer you seek is already given by proxy20. Just replace the file upload section of the code with a conversion to byte/stream set of codes.

Master @proxy20, give solution to this,,, Copy the following files to c:\windows\SysWow64..
jnifplib\win32\jnisgfplib.dll jnifplib\win32\jnisgwsqlib..
how do I go abt this? what does it mean? where is c:\windows\syswow64 located in my system? put me through pls

Don't let my boss hear u call me master......


just go to file explorer and search c:\windows\SysWow64

alternately click CTRL +F

copy the dil file by CTRL +C
and paste it in the required folder CTRL +V

Master @proxy20, I don't really understand ur explanation... Am using Windows 8.1...64 bit operating system... I have opened file explorer...I don't seems to figure out somethings..

This isn't programming just mere searching

Thanks Master @proxy20...u r the best in this field...it worked n over worked for me...don't know how to thank u..

Boss good morning@proxy20...the application was running well with sample program, but when I tried running with my program, it shows the no file in the java library path agsin.. At this point, am confuse...what should I do

OK sir , you just have to use the samples/examples and the .jar library for implementation your code is not recognized in the library .

Morning Master@proxy20..
My App captures image but crash after capturing the image with the error: Failed to write core dump. Minidumps are not enabled by default on client versions of windows..pls how do i solve this?;;am using Windows 8.1, 64bit os..
