Generation gs1 datamatrix barcode in Java BEYOND ANT S CORE TASKS

There are three other view controllers that you can use to allow users to interact with the Address Book.

namespace Example_5_12_ _ _ _The_while_Loop { class Program { public static void Main( ) { int counterVariable = 0; // while the counter variable is less than 10 // print out its value while (counterVariable < 10) { Console.WriteLine("counterVariable: {0}", counterVariable); counterVariable++; } } } }

You ll need to do that 20 times, once for each of the first 20 presidents. The URL is somewhat long, so you might want to cut and paste it, or you can download the code listing for this chapter from http://www.oreilly.com and cut and paste that part. Now you have a static data resource you can refer to in the rest of your XAML file; and that completes the Resources section.

/** * @param ssn the ssn to set */ public void setSsn(Long ssn) { this.ssn = ssn; } //--------------------------------------------------------------------------|| // Overridden Implementations ----------------------------------------------|| //--------------------------------------------------------------------------|| /** * {@inheritDoc} * @see java.lang.Object#hashCode() */ @Override public int hashCode() { final int prime = 31; int result = 1; result = prime * result + ((lastName == null) 0 : lastName.hashCode()); result = prime * result + ((ssn == null) 0 : ssn.hashCode()); return result; } /** * {@inheritDoc} * @see java.lang.Object#equals(java.lang.Object) */ @Override public boolean equals(Object obj) { if (this == obj) return true; if (obj == null) return false; if (getClass() != obj.getClass()) return false; ExternalEmployeePK other = (ExternalEmployeePK) obj; if (lastName == null) { if (other.lastName != null) return false; } else if (!lastName.equals(other.lastName)) return false; if (ssn == null) { if (other.ssn != null) return false; }

Very nice. Now you can go figure out whether you used the wrong object or you called the wrong method. Visual Studio .NET actually finds the error even before the compiler does. When you try to add a method, as soon as you type the dot character, IntelliSense pops up a list of valid methods to help you, as shown in Figure 3-1.

Next, we add the necessary lines of code to the handleOK method to trigger a datagram message to be sent.

... <s:validateAll> <div class="entry"> <div class="label">Username:</div> <div class="input"> <s:decorate> <h:inputText size="16" required="true" value="#{register.user.username}"/> </s:decorate> </div>

struct CanChange { public int Number { get; set; } public string Name { get; set; } }

pretty cool, and it covers all the bases that we listed in table 10.2. The component source code is available in its entirety at http://www.manning.com/crane. Rico can be found at http://openrico.org/ and Prototype at http://prototype. conio.net/.

com.sun.kjava.Database quoteDB = new Database (dbType, dbCreator, Database.READWRITE); if (!quoteDB.isOpen()) { Database.create(0, dbName, dbCreator, dbType, false); quoteDB = new Database (dbType, dbCreator, Database.READWRITE); }

Switch off the auto-commit mode. Use the same connection object for all the database updates. Commit the pending updates once all the operations succeed; otherwise, if any of the operations fail, we must roll back all the updates.

<asp:ValidationSummary ID="valSummary" runat="server" DisplayMode="BulletList" HeaderText="The following errors were found:" ShowSummary="true" />

Now that we know something about what SOAP is, let us see what it looks like. To do so we will create and send a SOAP message using our example scenario from section 4.2. Let us suppose that our distributor wants to know the price of a product with a product identifier of 123456. The distributor s system makes an RPC method call to the manufacturer using a SOAP message. The distributor calls a SOAP method named GetProductPrice and passes a

As you can see in listing 4.1, a thread dump looks a lot like an exception stack trace. The dump shows the call stack for every thread in the VM in addition to what locks the thread holds, where it s holding them, what locks the thread waits for and where it waits for them. Many times, when a thread hangs due to blocked I/O, you can do little to recover. You can, however, do your best to isolate temperamental operations from other operations and the client. We once worked on an application that accessed a highly secure database. The database required user-based authentication for each request, coupled with other implementation limitations, which forced a new connection for almost every request. (Users ran one or two queries at a time, negating any benefits that might be derived from pooling.) One day we came in to find that the entire application had inexplicably crashed, with no sign of a pending return, and our team was listed at the top of
