In light of this information, let s see how the MannersAspect (listing 2.3) would look if the weaving process produced pure Java code at the source code level. Note that in actuality, the AspectJ compiler produces byte code and not the Java code as shown here. We re showing you this code only to give you an idea of the source code that would be roughly equivalent to the byte code produced. Also, some of the details that are beyond the scope of this discussion have been omitted. First, let s examine the code in a class that would be equivalent to the aspect itself:

To build this application, you need to combine the components of the previous few sections. You know that our application requires a startup component and must also link against multiple libraries. Because the application interacts with the SQLite database, you must link against the sqlite library in addition to the c and android_runtime libraries. The full build script is shown in the next listing.

private DaoManager getDaoManager() { DaoManager tempDaoManager = null; Reader reader; try { reader = Resources.getResourceAsReader("Dao.xml"); tempDaoManager = DaoManagerBuilder.buildDaoManager(reader); } catch (Exception e) { e.printStackTrace(); fail("Cannot load dao.xml file."); } return tempDaoManager; }

You need to call RoleEnvironment.GetLocalResource, passing in the name of the local storage resource that you defined earlier (myStorage). The object returned by GetLocalResource exposes three properties (Name, MaximumSizeInMegabytes, and RootPath). The Name and MaximumSizeInMegabytes properties return the information that you set in the service definition file:

This query returns an Object[] with the starting and ending date of an item auction, and the name of the item all in uppercase. In particular, it s possible to call SQL aggregate functions.

Adding custom controls That completes the creation of the custom web part; all that remains is to create a web page to contain and display it and from now on we ll refer to web pages that contain web parts as web part pages, to distinguish them from ordinary web pages.

testLength++; testBox.Length = testLength;

Thread pooling is often used for high-performance server-side applications. The thread resource is unusual in that the resource destruction point is not as obvious as that in the call to a method such as close() . Further, since the resource thread, by definition, is an active resource it owns an execution flow of its own putting it in a resource pool is a bit interesting. Many application server providers internally recycle the threads to improve performance. However, other applications still require that each module that creates a new thread be modified to use the pool s API. In this section, we implement a simple AspectJ-based solution that cures the problem of invasiveness associated with the conventional solution.

interface is the ability to return query results as a ScrollableResults object. The ScrollableResults object allows you to move through the returned objects arbitrarily, and is typically useful for returning paged collections of objects, commonly found in web applications. Of course, our static queries aren t very useful in real applications. Real applications need to populate query parameters dynamically. JDBC s PreparedStatement interface supports setting positional query parameters dynamically, but populating queries can be cumbersome. Developers must know the type of each parameter in order to call the correct setter method in the interface. They also have to keep track of which positional parameter they are setting. Hibernate expands and improves on this notion by providing both positional and named query parameters.
