Since the upstroke exerts zero force, the downstroke must therefore exert a force equal to 2 times the weight of the bird in order for the average of the two numbers to equal the weight of the bird (If either the down- or upstroke lasted longer than the other, then we would calculate a weighted average, weighted according to the percentage of time of one wing beat cycle spent in each stroke).

Recall that the SimpleSessionApp example referred to above is a stateless session bean that takes a String argument, concatenates the string: back at you! , and returns the resultant string. The SimpleServiceApp does the same thing, except for the fact that it is a web service. Let s take a look the code that we ll borrow from each of these examples:

We ll start by using the session bean class code from the SimpleSessionApp example, which is in the Java source file, SimpleSessionBean.java:

Gimp is useful for rotating images. Open your image and select Tools Transform Tools Rotate. As you can see in Figure 3-13, rotating an image is achieved by simply changing the angle in the Rotate dialog box or by dragging the mouse over the image. Also, you can select the center of the rotation. For straightening photographs, this position should be set to the center of the image (which is the default), but feel free to try other values to create different effects.

Note that we re not going to use the session bean s home interface or bean interface classes. This is because the client in this example is a web service client. It will be invoking the methods of the service definition interface which is very similar to the bean interface, and it won t be using the home interface at all. Of course, you could leave those interfaces in, which would enable the deployed bean to be invoked via a web service client as well as via an EJB client. This is often a better approach, as it provides more flexibility as to how the session bean may be used.

The service definition interface is taken from the SimpleServiceApp example, SimpleServiceIF.java:

idx = str.LastIndexOf('h'); Console.WriteLine("Index of last 'h': " + idx); idx = str.IndexOf("ing"); Console.WriteLine("Index of first \"ing\": " + idx); idx = str.LastIndexOf("ing"); Console.WriteLine("Index of last \"ing\": " + idx); char[] chrs = { 'a', 'b', 'c' }; idx = str.IndexOfAny(chrs); Console.WriteLine("Index of first 'a', 'b', or 'c': " + idx); if(str.StartsWith("C# has")) Console.WriteLine("str begins with \"C# has\""); if(str.EndsWith("ling.")) Console.WriteLine("str ends with \"ling.\""); } }

package webservices; import java.rmi.Remote; import java.rmi.RemoteException; public interface SimpleServiceIF extends Remote { // the service methods public String getEchoString(String clientString) throws RemoteException; }

5:

The client for this example, SimpleServiceClient.java, is very similar to the client in the SimpleServiceApp example in the previous chapter: the basic difference is that we re going to take this opportunity to demonstrate how to use dynamic proxies mentioned in the previous chapter:

This program produces the following output:

package client; import webservices.SimpleServiceIF; import import import import java.net.URL; javax.xml.namespace.QName; javax.xml.rpc.Service; javax.xml.rpc.ServiceFactory;

Figure 3-13 This image shows the Rotate dialog box for Gimp After you select the Rotate tool, the Toolbox window, shown in Figure 3-14, shows the available options for the rotation Similarly to the guides when cropping, here we can add guides for straightening horizons or vertical lines You can enable this guide by selecting Grid in the Preview option With the help of this guide, you can align the photo with vertical/horizontal elements of it such as trees, buildings, and so forth As the rotated image will not fit in the original canvas, it is convenient to crop the resulting image to a more useful one You can do this by selecting Crop to result from the Clipping drop-down menu You can also increase or decrease the number of grid lines in the Toolbox window to better fit your image.
