Opencv Java Web Integration on eclipse ubuntu

Using opencv java , you can develop web application which uses opencv image processing libraries on the server.
1.) Eclipse Java J2EE version.
2.) Install opencv using configure and download opencv

Now, we will define OpenCV as a user library in Eclipse, so we can reuse the configuration for any project. Launch Eclipse and selectWindow –> Preferences from the menu.

Navigate under Java –> Build Path –> User Libraries and click New....

Enter a name, e.g. OpenCV-2.4.9, for your new library.
Now select your new user library and click Add External JARs....
Browse through /home/anish/opencv-2.4.9/build/lib and select opencv-249.jar. After adding the jar, extend the opencv-249.jar and select Native library location and press Edit....
Select External Folder... and browse to select the folder /home/anish/opencv-2.4.9. If you have a 32-bit system you need to select the x86 folder instead of x64.
Your user library configuration should look like this:

You have successfully configure opencv on eclipse. 
Now start creating a new Java project.

On the Java Settings step, under Libraries tab, select Add Library... and select OpenCV-2.4.9, then click Finish.

Libraries should look like this:
Now you have created and configured a new Java project it is time to test it. Create a new java file. Here is a starter code for your convenience:
import org.opencv.core.Core;
import org.opencv.core.CvType;
import org.opencv.core.Mat;

public class Hello
   public static void main( String[] args )
      System.loadLibrary( Core.NATIVE_LIBRARY_NAME );
      Mat mat = Mat.eye( 3, 3, CvType.CV_8UC1 );
      System.out.println( "mat = " + mat.dump() );

When you run the code you should see 3x3 identity matrix as output.

Now ,you have done with basic configuration with project.You are ready to use a powerful opencv with web applications. You can easily apply servlets/jsp and can use this codes in the server scripting.
