Hi,

what is the revision number of your currently used SDK?
Is this your application or sample from the SDK? If it is sample, then please provide steps how it would be possible to reproduce this issue: how it was compiled, from which folder and etc.

[Vinicius]

I'm working with SDK 4.1, revision number: 76570
running in folder "Samples\Biometrics\Java\abis-sample"
The code is: "D:\Neurotec_Biometric_4_1_SDK\Samples\Biometrics\Java\abis-sample> mvn package -Papplet"
It generates a folder on "D:\Neurotec_Biometric_4_1_SDK\Bin\Java\abis-sample-applet" with code of applet

Hello,

I have already asked you in another thread to update the 4.1 SDK, to the newest one. Could you, please do it?

Also, if it is possible for you, I would recommend to upgrade to the version 4.3.

Updated to the version 4.3, but now I have a new problem. I can't download dependency of libraries. Always occurs this error:

Hello, where I can find sample java code to show the minutia's marks into the fingerprint image

Hello,

MegaMatcher 4.3/VeriFinger 6.5 uses the NFView control to display the captured image and extracted minutes on it in Java. You can check the SimpleFingerSample or AbisSample, to see how it is done.

Hello,

I'm trying to test the Java MMSoapTest application found in the Neurotech Biometric SDK.

Product revision number: 91425

I compiled it under Eclipse, and remotely configured the NServer, altogether with the result of compiling the server_Soap_proxy.exe . Both applications are running in a remote machine.

When I run the MMSoapTest application, the Server console returns this error:
1344349932:socket.c:1147: sock_recv_packet_nolock: ERROR: low memory
And the Java Console returns this error:

Hello,

First of all, please make sure that you haven't mixed admin and client ports.
Another thing, please change NServer logging mode to 9 (edit NServer.conf Server.DefaultLogMethod) and run NServer once again. Send server.log to vaidasz at neurotechnology dot com

Hello Gil,

Did you use the Eclipse? If yes, then which version of the Eclipse do you use?
If you are not using the eclipse, then add jar files from the “/Bin/Java/” to your project.

Hello Gil,

Could you use Eclipse? We have instructions how to set up Eclipse to be able to use our SDK.

[GPaulino]

Hi,

I have sucessfully installed Eclipse Juno With J2EE, i can see all example, execute them but, as i see, we must need the Eclipse Tool environment in order to implement our project. This is fully recommended by Neurotechnology? There is another easier way to set our project with an Oracle java tool?

Thanks,

Gil

Hello,

we do not have restrictions, which development environment you could use for Java development. Our samples and tutorials are prepared to be built with Maven, but it does not means that you need to use it.
Generally speaking it is needed that you would include jar files from the "Bin\Java" folder and set the working directory to SDK folder with *.dlls (Windows) or *.so (Linux).

[rodrigo]

Is there any documentation about how to use Java with NServer?

[Martynas]

Is there any documentation about how to use Java with NServer?

Hello,

the documentation of the SDK contains a explanation what is the NServer and how to start it (section "5.2 Matching Server and Cluster"). Also the documentation has a description of the AbiSampleJava, which demonstrates how to send matching tasks to NServer, how to insert new records and receive matching results.
The SDK also contains tutorials in the "Tutorials\Server\Java" folder. These tutorials shows how functionality of the NServer can be used.

[rodrigo]

Thanks Martynas,
unfortunately i couldn´t find easy the way to insert new records. I checked in Abis application and did the same query but Nserver does not find my new record. I also tried to delete some records and he still find theses records what´s gives idea of NServer does not keep data updated with my table. Is there any documentation about how to make it works? I am using a simple server without cluster.

[Martynas]

I am using a simple server without cluster.

when the NServer/NClusterServer is used you need to insert/delete records in the database directly and inform the NServer/NClusterServer about made changes. After the insert/delete/change in the database was done, use the Admin.updateDBRecords method to pass inserted/deleted/changed records in the database ids to NServer. then NServer will fetch new data from the database.

[rodrigo]

Hi Martynas,
i am still having syncronize problems with nserver. I created an add functionalitty to finger but abis application does not find when i insert by my application. When i close the nserver and restart Abis works fine finding records that i inserted with my application. I tried admin.updateDBRecords(id) where id is and string array whith dbid, but i believe i need to do something more than this. do you have any idea?

[rodrigo]

one more information, when i use admin.updateDBRecords i receive the message below in the nserver console:

client_sock_thr: WARNING: received packet of unknow type 21, dropping

[rodrigo]

I found the solution in this topic http://www.neurotechnology.com/neurotec-forum/viewtopic.php?p=6081#p6102 . the problem was the port, i changed and its started to work.

What am I missing? I do have licenses available in a remote server, and I configured the NLicences line to pick licenses from that server. When I check that server's LicenceUsage.log, I see it took a Extractor Licence already.

Thank you

Hi,

did you set the working folder to folder with dlls, as it was described in the Vaidas' steps? You need add bin\win32_x86 (or win64_x64) directory to library path or just set application execution directory to it.

[Crisstina]

Yes, I did that step. Same results.

[Martynas]

Yes, I did that step. Same results.

could you provide this screenshot: right click on the project -> properties -> Java Build path -> Order and export

Hi,

before loading libraries in your application, try to use this code:

Code: Select all

System.setProperty("jna.library.path", path_to_native_libraries);


[marschupp]

Hi Martynas,
That seems to have helped. But after some trials I ended in the bad way of setting LD_LIBRARY_PATH to point to the correct Lib folder. And I load my jars with the JBoss module reading from my Neurotec Bin/Java folder.

I downloaded the Neurotec Biometric 4.3 trial version and installed it.
The installation folder is under c:\program files. Full path is C:\Program Files (x86)\Neurotechnology\Neurotec Biometric 4.3 SDK Trial.

I used the command "mvn clean install" in the Tutorial (or) Samples directory. The error is shown below. Please help me to solve this issue.
I have already set the path for javac and java.

Hi,

Is your Java compiler in the PATH ? Try to type "javac" at the command prompt. If javac is not found, then you should put your bin directory in the PATH. For example, in Windows, SET PATH=c:/jdk1.5.0_07/bin;%PATH%

This is not the full error message. Could you provide the full one?
This can actually happen if the application can not load the native dlls (on windows) or so (on Linux) files. Configure the application working folder as folder, where these dlls (so) files are located.

[GPaulino]

hi,

oki I got these dlls (Neurotec_Biometric_4_3_SDK_Trial\Lib\NCore.dll.lib ), but how can I use it? because I tried to put it into the C:\Windows\System32, tried changing the extensions .lib and to use the .dll into the same folder specified above, tried to put it in my sample project folder but it did not work................

then could you please tell me which is the correct path where I should place it??

Hi,

i was talking about dlls, not dll.lib files. Dlls are located in the "win32_x86" or "win64_x64" folder of the SDK.
Set your application working folder to be the same as the folder with dlls.

I don`t understand what I need to do exactly with these dll?, who can I to use it?, Im try to run your sample, Im using java language

1- created a new project ( prueba )
2- copy the java files from Neurotec_Biometric_4_3_SDK_Trial\Samples\Biometrics\Java\simple-faces-sample\src\main\java\com\neurotec\samples and created created the corresponding package com.neurotec.samples
3- import all the external library ( .jar ) that this need

I want to know the operation first and then create my own class.

when I prove the executable .jar file, this run perfectly, but when I run this using the eclipse send a message Unable to load library.

the com.neurotec.samples.util.LibraryManager class is the start all the process but,when I print the path that is using the result is "" and I havent any option to set the path.

if you are using the Eclipse and would like to see how the provided samples are working, then import them as it is described below:

1. Right Click in Eclipse Package Explorer and choose "Import"
2. Expand "Maven" and select "existing Maven Projects"
3. Then browse to SDK Samples folder and choose it.
4. Click Finish
5. Right Click on "simple-faces-sample"
6. Select "Debug As"
7. Select "debug configuration"
8. Double click on "Java Application"
9. Choose "Arguments" tab
10. Select "Other" as Working Directory
11. press button "File system" and browse to SDK "win32_x86" folder if yoru JVM is 32 bit or browse to "win64_x64" folder of the SDK, if your JVM is 64 bit.
12. Return to "Main" tab and define the main class as "com.neurotec.samples.SimpleFacesApplication"
13. apply and debug

Hi Martynas,

now Im studying the sample faces, where can I get the API for your classes to know the method??...........


thanks a lot for your helps!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ........................

Hi,

See documentation of the SDK, included in the SDK "documentation" folder.
