Drawer Data Matrix in Java CREATING ARCHIVE FILES

The services layer The services layer refers to an application s external environment, with which it collaborates in a variety of ways. A distributed application that does not touch external systems is rarely useful. The services layer accounts for tiers four through n of an n-tier application, since services can use other services and there is no theoretical limit to the number or variety of relationships between systems. As the developer of a specific application, the challenge at this layer is how to interact with the environment in the most effective way. 4 discusses this layer in detail and provides useful architectural patterns and techniques for integrating remote services into your J2EE-XML application. It explains your application integration options and covers the latest developments in this area from a J2EE and XML developer s perspective. 1.1.3 Overcoming common challenges

The log output shows that we no longer create new aspects for each control flow. Instead, only one aspect is created for each participant and a new TransactionContext object is created for each top-level operation s control flow. We now have a solution that allows us to use the participant pattern correctly with the transactionmanagement aspect. The participant pattern lets us separate the definition for transaction operations from various modules. Note how effectively we utilized all four patterns worker object creation, wormhole, exception introduction, and participant presented in chapter 8.

It should be fairly apparent that a value type also needs to be pretty lightweight, because of all that copying going on. Every time you pass it into a function, or assign it to a variable, a copy is made. And copies are generally the enemy of good performance. If your value type consists of more than two or three of the built-in types, it may be getting too big. These constraints mean it is very rare that you will actually want to declare a value type yourself. A lot of the obviously useful ones you might want are already defined in the .NET Framework class libraries (things like 2D points, times, and dates). Custom value types are so rare that it was hard to come up with a useful example for this book that wasn t already provided in the class libraries. (If you were wondering why our example application represents aircraft positions in such an idiosyncratic fashion, this is the reason.) But that doesn t mean you should never, ever declare a value type. Value types can have performance benefits when used in arrays (although as with most performance issues, this is not entirely clear-cut), and the immutability and copy semantics can make them safer when passing them in to functions you won t normally introduce side effects by working with a value type because you end up using a copy, rather than modifying shared data that other code might be relying on. Our polar 3D point seems to comply with the requirements. Any given point is just that: a specific point in 3D space a good candidate for immutability. (We might want to move a plane to a different point, but we can t change what a particular point means.) It is also no more than three doubles in size, which is small enough for copy semantics. Example 3-28 shows our declaration of this type, which we can add to our project. (As with enum, Visual Studio doesn t offer a template for value types. Again, we can use the Class template, replacing the class with the code we want.)

All these methods should appear by default in the table view controller subclass you create, but you may need to make changes to some of them to accommodate the specifics of your table. The first method is numberOfSectionsInTableView:. Tables can optionally include multiple sections, each of which has its own index of rows, and each of which can have a header and a footer. For this example, you re creating a table with one section, but we ll look at multiple sections before we finish this chapter. The second method, tableView:numberOfRowsInSection:, reports the number of rows in this section. Here, you return the size of the array you created. Note that you ignore the section variable because you have only one section. The third method, tableView:cellForRowAtIndexPath:, takes the table set up by the previous two methods and fills its cells one at a time. Although this chunk of code looks intimidating, most of it will be sitting there waiting for you the first time you work with a table. In particular, the creation of UITableViewCell will be built in. All you need to do is set the values of the cell before it s returned. Here you use your NSDictionary to set the cell s text color and text content B. Also note that this is your first use of the NSIndexPath data class. It encapsulates information on rows and sections. Cells have two views that you can access. The first is the textLabel. As you saw, this contains the text displayed in the cell. The other is imageView. It s basically an icon for the cell. You can set this to an image view. See section 11.2 for more information about using UIImage. You may want to change more than text content and color. Table 5.7 lists all the cell label features that you may want to experiment with at this point. Using these properties, you can make each table cell look unique, depending on the needs of your program.

This begs a question: what might cause a message to go unacknowledged by an MDB. As first-class EJB components, MDBs are transaction-aware in their own right. Often we want to execute the business logic, triggered by the arrival of a message, as an atomic business process. Let s look at our example again. The arrival of an OrderRequest message kicks off a sequence of actions: updating a database, accessing an external system, and sending notification. If any step fails, we want the entire business process to be rolled back. Using MDBs greatly simplifies handling messages within a transaction. MDBs can manage their own transactions or let the container manage transactions on their behalf. If CMT are used, then message consumption is included in the same transaction as the message handling logic. Only if the transaction succeeds will the message be acknowledged. It s an all-or-nothing proposition. If either of the following occurs while executing the onMessage() method, the transaction will be rolled back and the JMS server will attempt to redeliver the message:
Transaction-scoped persistence context
This means you don t have to reattach (with update() or lock()) a detached instance to delete it from the database. In this case, the call to delete() does two things: It reattaches the object to the Session and then schedules the object for deletion, executed on tx.commit(). The state of the object after the delete() call is removed. Reattachment of detached objects is only one possible way to transport data between several Sessions. You can use another option to synchronize modifications to a detached instance with the database, through merging of its state. Merging the state of a detached object Merging of a detached object is an alternative approach. It can be complementary to or can replace reattachment. Merging was first introduced in Hibernate to deal with a particular case where reattachment was no longer sufficient (the old name for the merge() method in Hibernate 2.x was saveOrUpdateCopy()). Look at the following code, which tries to reattach a detached object:

But our program expects numbers. We need to do something to convert the strings into numbers, and that s what double.Parse does: it expects the text to contain a decimal number, and converts it into a double-precision floating-point representation of that number. (If you re wondering what it would do if the text wasn t in fact a number, it ll throw an exception. 6 explains what that means and how to deal with it gracefully, but for now it means our program would crash with an error.) This example illustrates that method invocations can also be expressions the double type s Parse method returns a value of type double, meaning we can use it to initialize a variable of type double. But that s all by the by the point here is that our program now gets data that could be different each time the program runs. For example, a race engineer in the pit lane could run the program with new distance, timing, and fuel information each time the car completes a lap. So our program can now usefully make decisions based on its input using selection statements. One such statement is the if statement.
