[ 24 ]. 2 . This means that th e command was executed successfully. Now let"s have a look at the contents of the project just created. Refer to the following screenshot:.

As you can see, th none for none ere is plenty of everything. Note the items that will be most important for us in the beginning. First of all, there are two subdirectories under \t5first \src and \target.

. [ 25 ]. Creating Your Working Environment The \src subdirect ory, as you can guess, contains the source code of the application, including Java files, template files, and the standard deployment descriptor, web. xml (if you are new to Java web applications" terminology, please read Appendix A, which provides an overview of the most essential concepts). Note that there are two files with the name Start, but with different extensions.

The Start.java source file is located in \main\java subdirectory, under the structure of subdirectories reflecting its package name (com.packtpub.

t5first.pages), while the Start.tml file is located in the \main\webapp subdirectory.

These are two parts of the same Tapestry page, and this sort of duality will be discussed properly in the next chapter.. There is actually none none more than one copy of the Start.tml file in the contents of these directories because Maven did its work in two steps. It first created all the necessary files under the \src subdirectory and then created the structure of the future application under the \target subdirectory.

You will follow my logic more easily if you spend some time looking at the picture of the directories, and compare it with the structure you"ve got on your computer.. Under the \target subdirectory, we will find the result of building and packaging the application by Maven. There is already the end product, t5first.war file.

We can take it and deploy it on a Java-enabled web server (like Tomcat). It has everything required for a Tapestry Web application. However, there are also the intermediate results of Maven"s work.

The \classes subdirectory contains compiled Java classes, while under \t5first, you will find a familiar template file, Start.tml, and under \t5first\WEB-INF, the deployment descriptor web.xml.

Most remarkably, the \t5first\WEB-INF\lib subdirectory contains all the necessary libraries downloaded for us by Maven from across the Internet. We didn"t have to figure out what is required and where to get it. At this point, we can thank Maven for its service as we are going further.

The next step is to start working with the source of the application, building it and deploying to a server. This is where a contemporary IDE will be very helpful..

Please note that i none none f Maven didn"t work for you for some reason, the code package for this chapter contains the complete project tree created by Maven, and you can start further work from it.. [ 26 ]. 2 . Install NetBeans Even if you decide none for none d to use Eclipse, I still recommend you to read this section as starting a new project in NetBeans is significantly simpler. Go to http://www.netbeans.

info/downloads and download the latest package for your platform. Install it with all the default options. Your working environment is ready.

Now let us use NetBeans to work with the project created for us by Maven. Start the IDE and in its menu choose File . New Project...

(o r press the second from the left button on the toolbar). You will see the New Project dialog opened. In it, select Web under Categories and Web Application with Existing Sources under Projects, as shown in the following figure, and click on Next:.
