This is where EJB and JPA come in. Starting with EJB 3.0, a session bean class is a simple Java class that implements a regular Java interface, and in EJB 3.1 even the interface is no longer required for local beans. No special EJB interfaces need to be extended or implemented. To unit test the logic in a session bean, we can usually just implement it and execute it. If the bean depends on another bean, we can instantiate that bean and manually inject it into the bean being tested. The EJB 3.0 release was designed to encourage testing by breaking the hard dependencies between application code and the application server. Likewise entities are a world apart from container-managed entity beans. If your session bean uses an entity, you can just instantiate it and use it like any other class. If you are testing code that uses the entity manager and want to verify that it is interacting with the database the way you expect it to, just bootstrap the entity manager in Java SE and make full use of the entity manager outside of the application server. In this chapter, we will demonstrate how to take a session bean and JPA code from a Java EE application and run it outside the container using unit testing and integration testing approaches. If you have worked with older versions of EJB and experienced the pain of developer testing, prepare yourself for a completely different look at testing enterprise applications. how to create a thumbnail image of a pdf in c# Generate a pdf thumbnail (open source/free) - Stack Overflow

The more opaque circles tend to be in the center of the alpha mask: private BufferedImage alphaSplash() { Random rand = new Random(); // create a grayscale buffered image BufferedImage img = new BufferedImage(ALPHA_SIZE, ALPHA_SIZE, BufferedImage.TYPE_BYTE_GRAY); Graphics2D g = img.createGraphics(); // draw into it g.setColor(Color.black); // fully transparent g.fillRect(0, 0, ALPHA_SIZE, ALPHA_SIZE); int radius = 3; // circle radius int offset = 8; // offset of boxed circle from top-left of graphic g.setColor(new Color(0.3f, 0.3f, 0.3f)); //near transparent circles boxedCircles(offset, offset, ALPHA_SIZE-(offset*2), radius, 100, g, rand); offset = 12; g.setColor(new Color(0.6f, 0.6f, 0.6f)); // mid-level translucent boxedCircles(offset, offset, ALPHA_SIZE-(offset*2), radius, 80, g, rand); offset = 16; g.setColor(Color.white); // fully opaque circles boxedCircles(offset, offset, ALPHA_SIZE-(offset*2), radius, 50, g, rand); g.dispose(); return img; } // end of alphaSplash() boxedCircles() draws circles whose centers are somewhere within the square defined by boxedCircles() input arguments: private void boxedCircles(int x, int y, int len, int radius, int numCircles, Graphics2D g, Random rand) /* Generate numCircles circles whose centers are within the square whose top-left is (x,y), with sides of len. A circle has a radius equal to the radius value. */ { int xc, yc; for (int i=0; i < numCircles; i++) { xc = x + (int)(rand.nextDouble()*len) - radius; yc = y + (int)(rand.nextDouble()*len) - radius; g.fillOval(xc, yc, radius*2, radius*2); } } Figure 6-19 shows some splash shapes drawn against a plain white floor viewed from above.

C# tool for generating image thumbnails from pdf files - lmorelato/ pdf - thumbnail . Two important concepts of object-oriented programming are objects and classes. You re now going to discover what these mean and how they relate to the JavaScript language. The JUnit test framework is a de facto standard for testing Java applications JUnit is a simple unit testing framework that allows tests to be written as Java classes These Java classes are then bundled together and run in suites using a test runner that is itself a simple Java class Out of this simple design, a whole community has emerged to provide extensions to JUnit and integrate it into all major development environments Despite its name, unit testing is only one of the many things that JUnit can be used for It has been extended to support testing of web sites, automatic stubbing of interfaces for testing, concurrency testing, and performance testing Many quality assurance groups now use JUnit as part of the automation mechanism to run whole suites of end-to-end functional tests. pdf to thumbnail converter c# Create Thumbnail Image from PDF using Ghostscript - CodeProject

Splash shapes on a white surface There s no absolute requirement that the alpha mask has to be generated at runtime. It s quite possible to load a grayscale image from a file, as in this example: // in getAlphaTexture() alphaIC.set( loadAlpha("alpha.gif") ); loadAlpha() is private BufferedImage loadAlpha(String fnm) { try { return ImageIO.read( new File("images/" + fnm)); } catch (IOException e) { System.out.println("Could not load alpha mask: images/" + fnm); return null; } } The file must use 8-bit grayscales, and be ALPHA_SIZE*ALPHA_SIZE large. For our purposes, we will look at JUnit in the context of its unit testing roots, and also at strategies that allow it to be used as an effective integration test framework Collectively we look at these two approaches simply as developer tests because they are written by developers to assist with the overall quality and development of an application In addition to the test framework itself, there are other libraries that can assist with the testing of Java EE components The EJB 31 release introduced the embedded EJB container, providing developers with many of the services of an EJB container without the requirement to run within an application server Many nonstandard frameworks also offer sophisticated dependency injection support even in the Java SE environment, allowing dependent classes to be woven together Even if a framework does not directly support EJB 3. generate pdf thumbnail c# Generate thumbnail image for office document in c# - MSDN - Microsoft
