SOA Tools or Integration Tools

I agree with David Linthicum opinion on the recent SOA Tools. Click on the link to read the complete article...

SOA Vendors Focus Too Much on Integration . . .
— We've all experienced the hype: "We're a SOA tool, and we're here to help!" However, most SOA vendors out there don’t understand the value of SOA, or even how to approach SOA. They focus on the tactical and not the strategic. Why? A tactical approach is easier for them to sell, and easier for them to understand. However, this approach means they are selling their customers short.

Time Zones in Java

Here is a complete list of Java TimeZone codes and their details.

Java Timezones Complete List

To get java.util.TimeZone instance for EST, following code can be used.


TimeZone estZone = TimeZone.getTimeZone("America/New_York");


To create a Calendar object with EST Timezone, following code can be used.


Calendar cal = GregorianCalendar.getInstance(TimeZone.getTimeZone("America/New_York"));


Image Resize

Following is sample Java code for reading an Image dimensions and to Resize image while preserving aspect ratio.

import java.awt.Image;
import java.awt.image.BufferedImage;
import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;

import javax.imageio.ImageIO;

public class ImageTest {
  public static void main(String[] args) {
      try {
          System.out.println("Before reading...");
          BufferedImage bi = readImage("D:\\temp\\itsecurity.jpg");
          System.out.println("After reading...");

          printImageProperties(bi);

          BufferedImage scaledBufImg = scaleImageToWidth(bi, 200);

          System.out.println("Writing new img...");
          File modImg = new File("D:\\temp\\itsecurity_mod.jpg");
          ImageIO.write(scaledBufImg, "jpeg", modImg);

      } catch (Exception e) {
          e.printStackTrace();
      }
  }

  public static BufferedImage scaleImageToWidth(BufferedImage bi, int newWidth) throws Exception {
      int iw = bi.getWidth();
      int ih = bi.getHeight();
      // Getting aspect ratio
      double ratio = (double) iw / (double) ih;
      // Calculate new height
      int newheight = (int) (newWidth / ratio);
      System.out.println("Scaling... " + newWidth + " X " + newheight);
   
      // Get Scaled image
      Image scaledImg = bi.getScaledInstance(newWidth, newheight, Image.SCALE_SMOOTH);
   
      // Create new writable Image
      BufferedImage scaledBufImg = new BufferedImage(newWidth, newheight, BufferedImage.TYPE_INT_RGB);
      scaledBufImg.getGraphics().drawImage(scaledImg, 0, 0, null);
      return scaledBufImg;
  }

  public static void printImageProperties(BufferedImage bi) throws Exception {
      System.out.println("Dimensions(WxH):" + bi.getWidth() + " X " + bi.getHeight());
      System.out.println("MinX:" + bi.getMinX() + ", MinY:" + bi.getMinY());
  }

  public static BufferedImage readImage(String path) throws Exception {
      File imageFile = new File(path);
      InputStream is = new FileInputStream(imageFile);
      BufferedImage bi = ImageIO.read(is);
      return bi;
  }

  public static BufferedImage readImage(byte[] bytes) throws Exception {
      ByteArrayInputStream bis = new ByteArrayInputStream(bytes);
      BufferedImage bi = ImageIO.read(bis);
      return bi;
  }
}
