It s possible to generate the satellite assemblies manually from the source .resx files without rebuilding the entire project in Visual Studio. You will have to use the Windows command line (cmd.exe), and you will need access to the main assembly s EXE or DLL file. It s not for the faint of heart, and a single mistyped character could cost American taxpayers millions. Figure 19-1 summarized the steps needed to move a .resx file into a satellite assembly. The generate and compile steps can be done using two command-line utilities: resgen.exe and al.exe. Doesn t that sound like great fun As with other .NET command-line tools, these tools need the command-line environment to be set up just so, or they will have a snit and refuse to run. To ensure that you have the correct environment, you need to open the special .NET version of the command line. The .NET SDK was installed when you installed the framework, so you should be able to find a Start-menu entry for it at Start [All] Programs Microsoft Visual Studio 2008 Visual Studio Tools Visual Studio 2008 Command Prompt.

Table 2.3 These subtasks can be added to your <ejbdoclet/> task to generate the vendor-specific deployment XML for your EJBs. Along with each subtask are associated JavaDoc comments in order to help XDoclet completely generate the XML. Refer to the XDoclet documentation for more information about each of these tasks. Application Server Weblogic JBoss Subtask <weblogic/> <jboss/> Comments Generates descriptors for versions 6.0 and 6.1 Generates the jboss-xml and jaws.xml files (continued on next page)

So far, we ve focused on some fairly basic, yet crucial, J2ME concepts. In chapter 14, we ll discuss the J2ME runtime environment in detail, but to round out this introductory discussion, we ll briefly introduce it here. There are two basic ways to run J2ME applications on devices. One way is to run them transiently over the network. In this mode of operation the application is loaded into memory by downloading it over the network. Once the application finishes running, the application is discarded. Running applications in this manner requires a network connection. Applications can also be installed onto the device. In this case, an application is available to run with or without a network connection. Regardless of the method used to run J2ME applications, some device-specific management is involved on the part of the J2ME implementation running on the actual device. The part of the J2ME environment responsible for managing applications on the device is called the Java Application Manager (JAM). Implementation of the JAM is something that is implemented by the device manufacturer. The JAM itself manages activities such as downloading, installing, inspecting, launching, and uninstalling Java applications on the device. Most devices in the J2ME space will be shipped with the Java environment already on the device. This is good in that the users of the device, and ultimately the application, will not have to deal with loading the Java Runtime Environment. However, this also means there may only be one JRE available on the device. Since different manufacturers will inevitably release versions of their products at different times with different JREs, the code may need to be compatible across a number of different J2ME runtime versions depending on how the device handles this situation. 14 discusses concepts such as class file verification, class loading, virtual machine lifecycles and responsibilities, threading, and garbage collecting.

If you don t supply a qualifying number of decimal digits, as Example 10-10 shows, it just uses as many as necessary.

In addition to having to write a lot of boilerplate code, a significant hurdle in managing EJB 2 was the fact that you still had to do a lot of XML configuration for each component. Although XML is a great mechanism, the truth is that not everyone is a big fan of its verbosity, poor readability, and fragility. Before the arrival of Java 5 metadata annotations, we had no choice but to use XML for configuration. EJB 3 allows us to use metadata annotations to configure a component instead of using XML deployment descriptors. As you might be able to guess from listing 1.1, besides eliminating verbosity, annotations help avoid the monolithic nature of XML configuration files and localize configuration to the code that is being affected by it. Note, though, you can still use XML deployment descriptors if they suit you better or simply to supplement annotations. We ll talk more about this in chapter 2. In addition to making the task of configuration easier, EJB 3 reduces the total amount of configuration altogether by using sensible defaults wherever possible. This is especially important when you re dealing with automated persistence using ORM, as you ll see in chapters 7, 8, 9, and 10.

By simply extending a reusable aspect, we have the required indentation effort. You will see additional examples of the IndentedLogging aspect in part 3. 5.5.3 Aspect precedence Generally, you want the logging aspects to have the highest precedence. This way, the logging aspect s before advice executes before any of the other aspects before advice, and the logging aspect s after advice executes after the other aspects after advice. You can implement this requirement by making the logging aspects dominate all other aspects by using the following construct:

void setLastName (java.lang.String lastName) { this.lastName = lastName; } java.lang.String getLastName () { return lastName; } void setMinimumAge (java.lang.Integer minimumAge) { this.minimumAge = minimumAge; } java.lang.Integer getMinimumAge () { return minimumAge; } void setStartDate (String startDate) { this.startDate = startDate; } String getStartDate () { return startDate; } void setActive (boolean active) { this.active = active; } boolean isActive () { return active; } public void reset(ActionMapping mapping, HttpServletRequest request) { setLastName(""); setMinimumAge(null); setStartDate(""); setActive(false); } }

Note that the query uses the special HQL elements() function (explained later) to select all elements of a collection. The most important reason for the existence of collection filters is to allow the application to retrieve some elements of a collection without initializing the entire collection. In the case of very large collections, this is important to achieve acceptable performance. The following query retrieves all bids made by a user in the past week:

Each rotor is a disk with 52 electrical contacts, 26 on one face and another 26 on the other. Inside the disk each contact is wired to another on the opposite face. Electric current entering at position 1 might exit on the other side in position 8, for example. The output from one rotor was passed into the next through the contacts on the faces, forming a circuit. In figure 9.1 current entering Rotor A in position 1 leaves in position 8. Position 8 in the next rotor is wired to position 3, and 3 in the last rotor is wired to 22. The final component, the reflector, directs the current back through the rotors in the reverse direction. This ensures that pressing A will give W and (more important, when it comes time to decode) pressing W will give A.
