So, what is an optional task In previous versions of Ant, the term optional task referred to those tasks not normally distributed with Ant; they were in an add-on library that users downloaded separately. As of version 1.5, Ant ships with complete sets of core and optional tasks. But there are still distinctions between the two task types. Ant s optional tasks are stored in different libraries and the online documentation divides tasks into core and optional. With current distributions, the distinction between core and optional tasks may seem odd or unnecessary, but there are some remaining differences. A key one is that optional tasks are generally viewed as less essential than the core tasks to the majority of build files. Although <junit> is an optional task, we consider it to be a mandatory feature in all build files. The other difference is that nearly all the optional tasks depend upon external libraries or programs to work. Unlike core tasks, optional tasks are not typically stand-alone. Thus to use nearly any optional task, you must download and install the extra libraries or programs. These additional downloads have been the source of many support issues. The expectation by many users was that once the optional JAR was downloaded, everything would work. When it didn t, many concluded there was a bug in Ant. As a consequence of the many erroneous bugs reported, the error message 235

ASP .NET continues to support ASP .NET 1 .x style code behind . This can be important to understand if you ever run into any legacy code from that era . Using the code-behind directives in the .aspx file, you provide the code to run behind the page in a separate class and use the Page directive to tell ASP .NET which class to apply to the page . Then, you tell ASP .NET the name of the file containing the source code for the class . For example, imagine this code is placed in a file named HelloWorld4Code .cs:

To detect interoperability problems early, we need to create a client with a different SOAP toolkit and then verify that it can call our service. Although we could use the Sun web services toolkit, we chose, instead, to make life seemingly more complex by creating a C# client. It is a little known fact that there is a task in Ant to compile C# programs, the <csc> task, and that Ant 1.5 added the <wsdltodotnet> task to go alongside <csc>, purely to make C#-based interoperability testing inside Ant possible and easy. Because these tasks call down to programs

using System.Web; public class HelloWorld4Code : System.Web.UI.Page { public void ShowLineage() { Response.Write("Check out the family tree: "); Response.Write(this.GetType().ToString()); Response.Write(" which derives from: "); Response.Write(this.GetType().BaseType.ToString()); Response.Write(" which derives from: "); Response.Write(this.GetType().BaseType.BaseType.ToString()); Response.Write(" which derives from: "); Response.Write( this.GetType().BaseType.BaseType.BaseType.ToString()); Response.Write(" which derives from: "); Response.Write( this.GetType().BaseType.BaseType.BaseType.BaseType.ToString()); } }

in the .NET framework SDK, they only work on a Windows PC with the SDK installed. You do not need the commercial Visual Studio.Net, just the downloadable SDK. The jEdit editor has a C# mode for editing, and we will build with Ant. The Ant .NET tasks have not been tested with either the Rotor public source version of .NET for FreeBSD or with the Ximian team s Mono implementation. Building a .NET client for our service is nearly identical to building a Java version: we run a program to generate the stub classes, add an entry point class, build them, and then run the program with our chosen arguments. See figure 15.5.

// The following function checks for dates between 10/5/1582 and 10/15/1582 // which are dates excluded on the original Gregorian Calendar private static bool IsInvalidGregorianCalendarDate (int year, int month, int day) { if (year == 1582 && month == 10 && !(day < 5) && !(day > 14) { return true; } return false; }

Figure 15.5 The stages of building and running a C# client match that of the Java client, except that we cannot generate unit tests automatically. We still implement the web service in Java.

An ASP .NET page that uses the HelloWorld4Code class to drive the page might then look like this:

Probing for the classes Because we are only supporting the Windows implementation of .NET, we can only build the .NET client on Windows, and then only those versions with the .NET SDK installed and on the PATH. How do we restrict this With a few moderately complex conditions:
