EmailMessageProducer (the DefaultEmailMessageProducer) uses implementations of the EmailMessageTemplateSource and EmailMessageMerger. The task of the EmailMessageTemplateSource is to look up the e-mail template identified by its code; the merger will take the content of the template and merge it with the arguments to produce the final EmailMessage, which is almost ready to be queued using the EmailService. By almost ready, we mean that the message body and subject are set; all that remains to be done is to specify the recipient and add any potential attachments. As you can see, there are important things to consider in a real implementation. The e-mail templates should be stored externally, perhaps on the filesystem or in the database. Also, including the locale is important when looking up the e-mail templates. You may argue that your application does not need to support different languages, but adding this feature is easy, and you can always produce templates in your default language. When implementing the scheduler, you should add some management information: you may find it useful to track the numbers of retry e-mails sent, the size of the queue, and many other values.

instances that can then be organized into one or more Central Management Server groups. You can view the Central Management Servers from the Registered Servers window of SQL Server Management Studio, as shown in Figure 1-7.

The final section of this chapter deals with error reporting. This is an extremely important aspect of good application design. With enough information about the errors that occur, debugging becomes a lot easier. However, recording just enough information about application failures is very tricky. I am sure you would never write code similar to that shown in Listing 8-19. Listing 8-19. Bad Example of Error Handling public class SimpleClient { private FileUploadService fileUploadService; private static final Log logger = LogFactory.getLog(SimpleClient.class); public void uploadTerrible() { try { this.fileUploadService.upload("me", "text/plain", System.currentTimeMillis(), new byte[] { 1, 2, 3 }); } catch (Exception e) { // Go away! } } public void setFileUploadService(FileUploadService fileUploadService) { this.fileUploadService = fileUploadService; } } Silently ignoring exceptions is not good practice in Java (or any other type of) programming. The code in Listing 8-19 gives no feedback to the user in case of an error. When the users complain that the application did not work as it should, the programmers may find it hard to reproduce the problem. A solution that addresses some of these issues is shown in Listing 8-20. Listing 8-20. Slightly Improved Error Logging public class SimpleClient { private FileUploadService fileUploadService; private static final Log logger = LogFactory.getLog(SimpleClient.class); public void uploadBetter() { try { this.fileUploadService.upload("me", "text/plain",

If SOA isn t considered for all new development or all the future enhancements for the existing systems, we will fail in implementing service orientation..

System.currentTimeMillis(), new byte[] { 1, 2, 3 }); } catch (Exception e) { logger.error(e); } } public void setFileUploadService(FileUploadService fileUploadService) { this.fileUploadService = fileUploadService; } } The code here addresses the issue of silently swallowing the exception. However, it simply writes it out to a log. Now, even if we turned the logging down to the ERROR level, if we had 1,000 requests, the log would still contain 26 lines; at the DEBUG level, we would have to go through 2,865 lines to locate the errors! However, we are still missing more information about the errors. We get the message, but that is usually not enough information. Ideally, we would have the method arguments that contain additional information, so that we can create a test to expose the failure. In addition to this, it would be better if we didn t have to scan through the log files to find problems. Consider this solution: for every service-layer method call, we create an around advice that logs the arguments supplied and proceeds with the invocation. If the invocation fails with an exception, we write the details of the exception to a database, together with the method arguments and stack trace. We then transparently rethrow the exception so that the clients do not notice that there was advice. The database could very quickly become clogged with exception reports. Chances are, however, that most of the exceptions will be the same or very similar. Therefore, we can record a count of each exception. Ultimately, we would like to see a report that looks like Table 8-1. Table 8-1. Sample Exception Report

Listing 6-31. Sample Application for the After Throwing Advice public class AfterThrowingDemo { public static void main(String[] args) { ApplicationContext ac = new ClassPathXmlApplicationContext( "/META-INF/spring/afterthrowingdemo1-context.xml" ); UserService userService = (UserService) ac.getBean("userService"); userService.login("janm"); StockService stockService = (StockService) ac.getBean("stockService"); System.out.println(stockService.getStockLevel(null)); } } Even though we have written after throwing advice (and configured the beans correctly in afterthrowingdemo1-context.xml), the advice does not get executed, because the type of the exception in its argument is IOException, not NullPointerException. If we change the advice s argument to Exception, it will work, printing the following. ... Exception in thread "main" java.lang.NullPointerException After method call of java.lang.NullPointerException at com.apress.prospring2.ch06.services.StockService. getStockLevel(StockService.java:9) ...
