// Show the FlowerFrame.
final FlowerFrame frame = new FlowerFrame(flowers);
frame.setVisible(true);
在 main 方法主体中，添加代码以将客户端连接到服务。
// The client connects to the service with this code.
FlowerServiceService service = new FlowerServiceService();
final FlowerService port = service.getFlowerServicePort();
在 main 方法主体中，添加代码，创建一个具有四个 Runnable 线程的数组，并在每个线程中调用一次 Web 服务的 getFlower 操作。
// The web service getFlower operation
// is called 4 times, each in a separate thread.
// When the operation finishes the picture is shown in
// a specific button.
Runnable[] tasks = new Runnable[4];
for (int i=0; i<4;i++) {
final int index = i;
tasks[i] = new Runnable() {
public void run() {
try {
// Call the getFlower operation
// on the web service:
Image img = port.getFlower(FlowerFrame.FLOWERS[index]);
System.out.println("picture downloaded: "+FlowerFrame.FLOWERS[index]);
// Add strings to the hashmap:
flowers.put(FlowerFrame.FLOWERS[index],img);
// Call the showFlower operation
// on the FlowerFrame:
frame.showFlower();
} catch (IOException_Exception ex) {
ex.printStackTrace();
}
downloadedPictures++;
}
};
new Thread(tasks[i]).start();
}
在 main 方法主体中，添加代码以在单独的线程中调用 Web 服务的 getThumbn ils 操作。
// The web service getThumbnails operation is called
// in a separate thread, just after the previous four threads finish.
// When the images are downloaded, the thumbnails are shown at
// the bottom of the frame.
Runnable thumbsTask = new Runnable() {
public void run() {
try {
while (downloadedPictures < 4) {
try {Thread.sleep(100);} catch (InterruptedException ex) {}
}
// Call the getThumbnails operation
// on the web service:
List<Image> images = port.getThumbnails();
System.out.println("thumbs downloaded");
if (images != null && images.size() == 4) {
for (int i=0;i<4;i++) {
thumbs.put(FlowerFrame.FLOWERS[i],images.get(i));
}
frame.setThumbnails(thumbs);
}
} catch (IOException_Exception ex) {
ex.printStackTrace();
}
}
};
new Thread(thumbsTask).start();
在 Main.java 中修复导入（如果在代码中粘贴导入内容时未对其进行修复）。通过在编辑器中单击鼠标右键，然后从上下文菜单中选择“修复导入”，可以一次性修复所有导入内容。您可以选择要导入的 List 类；请选择 java.util.List。下面是完整的导入语句集：
public class Main {
private static int downloadedPictures;
public static void main(String[] args) {
final Map<String,Image> flowers = new HashMap<String,Image>(4);
final Map<String,Image> thumbs = new HashMap<String,Image>(4);
// Show the FlowerFrame.
final FlowerFrame frame = new FlowerFrame(flowers);
frame.setVisible(true);
// The client connects to the service with this code.
FlowerService_Service service = new FlowerService_Service();
final FlowerService port = service.getFlowerServicePort();
Runnable[] tasks = new Runnable[4];
// The web service getFlower operation
// is called 4 times, each in a separate thread.
// When the operation finishes the picture is shown in
// a specific button.
for (int i=0; i<4;i++) {
final int index = i;
tasks[i] = new Runnable() {
public void run() {
try {
// Call the getFlower operation
// on the web service:
Image img = port.getFlower(FlowerFrame.FLOWERS[index]);
System.out.println("picture downloaded: "+FlowerFrame.FLOWERS[index]);
// Add strings to the hashmap:
flowers.put(FlowerFrame.FLOWERS[index],img);
// Call the showFlower operation
// on the FlowerFrame:
frame.showFlower();
} catch (IOException_Exception ex) {
ex.printStackTrace();
}
downloadedPictures++;
}
};
new Thread(tasks[i]).start();
}
// The web service getThumbnails operation is called
// in a separate thread, just after the previous four threads finish.
// When the images are downloaded, the thumbnails are shown at
// the bottom of the frame.
Runnable thumbsTask = new Runnable() {
public void run() {
try {
while (downloadedPictures < 4) {
try {Thread.sleep(100);} catch (InterruptedException ex) {}
}
// Call the getThumbnails operation
// on the web service:
List<Image> images = port.getThumbnails();
System.out.println("thumbs downloaded");
if (images != null && images.size() == 4) {
for (int i=0;i<4;i++) {
thumbs.put(FlowerFrame.FLOWERS[i],images.get(i));
}
frame.setThumbnails(thumbs);
}
} catch (IOException_Exception ex) {
ex.printStackTrace();
}
}
};
new Thread(thumbsTask).start();
}
}
现在该客户端应用程序完整了，具有与 Web 服务交互的代码，该 Web 服务委托给了 EJB 模块，以公开其图像。右键单击客户端，然后选择“运行”。将启动 Swing 应用程序，并且之后会填充从 Web 服务接收到的图像。如果图像没有全部出现，请清理并生成 FlowerService 项目，然后再次运行。请注意，可以通过选择单选按钮或者单击缩略图来更改主框架中显示的图像。
