TranscriptHello. Everybody please be welcome. Let's start right now a new Java Struts course provided by MrBool. Java Struts it's a software provided by Apache Software Foundation. What means Struts? Struts is a web framework, free open source solution for creating Java web applications. At this first time let's download all the software needed to begin our study. Take a look at this web page. Here you'll find the official Struts web page provided by Apache Software Foundation. Here you will find all information needed to provide you a tool to develop Struts application. We are going to use it as a byline to provide us all information needed. At this first time and at this course, of course we're going to study Struts 2. All right. To run any Java application you have to have installed on your machine a Java run time environment or a Java development kit. You choose one of them. I'm going to choose the Java run-time environment and I will download it. You have to make this download. You have to install this on your machine. This is a very simple installation, it will not have any kind of difficult imposed to this. After that the next step is to download the Apache Tomcat.

Apache Tomcat is a web container that will provide us access to the web application. We are going to use the version number 7. You may find your download here to your Windows machine. We're going to install the Tomcat as a Windows Server C. We think we will be better provided to our needs. So, make your download. Let's run. Here you have to select your type of install, we recommend you to use a full install. The Tomcat will install some kind of options that may help us in the future. In this frame you find some nice and important information that we must concern about that. The first three information tell us to choose the option about the port to have a server shut down port, an HTTP connection ports. This port will provides us access to the Tomcat manager provided in a web-page . That's very important. After that you have to choose a name for your Windows Server C. We are going to call it STomcat 7, not the full name. You can create shortcuts for all users here and after that you have to choose and log in user name and a password. I'm going to set admin for user name and password. In here the Tomcat will inform and include some roles to these users. Some administration roles of course.

After that the program will inform the folder where the Java run-time environment is installed, a destination folder. After that just install. OK. You can run the Tomcat right now. All right. At this point, how can I make an access to Tomcat? It's simple. You go to your web browser and you type, local host at the port 8080, and you got it. If are seeing these, you've successfully installed the Tomcat. Congratulations. This is the main web page from Tomcat. All the management page is provided by these link called manager APP. Here you type your user name and your password. OK. Here you are. Here you have all the options and all the applications installed and deployed to the Tomcat web application manager. Here you'll find it. You have documentation page providing information about the Tomcat software. You have some kind of examples, servelets and JSP. OK. You have the manager that right at this page we are reviewing now. Below this section of the document you'll find deploy option that here you can deploy, upload our word file that you can deploy directly to Tomcat. At this point the next step is to download the Eclipse downloads web-page, right here, and download Eclipse for Java either loopers. You must choose your version between 32 to 64 bit and make a download. The download provided by Eclipse is very simple to install. You will receive a zip package. You just have to unzip all the contents in a folder on your computer and momentarily Eclipse will be installed.

The next step is to download Struts 2 components to run Struts application. As we talk earlier the Struts is a framework a nice way to provide web applications. Let's download the components needed to make it. You have several options to download in this web-page for downloads. We are going to use just the essential dependence because we don't need more then these to start developing our Struts application. Of course, after this first moment you can download the full distribution but right now we are going to use just the essential dependences to provide our main applications. At this moment you only have to download this main content. You are going to find some libraries inside the zip file. You just have to unzip all them on a folder and wait. That we are going to use a lot in the future. This is the main structure provided by the zip file. You have some text files, and you have a folder named Leeb. That contains a lot of jar files. We are going to use a bunch of them to develop our applications. After seeing these you just have to open your Eclipse 2, and you're going to take a look for some options here. First of all go to minute window, preference, and you have a Tomcat options. You must select the version 7. You must set the folder where Tomcat is installed. You'll find here. Tomcat 7. Here you go. After that you have some options that we are not going to set right now. The run- time settings, goes here. At this time, we'll have to set the manager applications settings.

First of all you have to type here your user name and password that you previously selected. Click and apply. OK. Right. Let's take a nice look on this folder where Tomcat is installed. You have here a folder named Leeb. What do you find here? You find several files that compose the Tomcat environment. After that you have a logs folder. Here you find several files separated by date and type. This is the main source to find anything that goes wrong or right in your application. This is the full login system of Tomcat. Let's take a look at one of these file. So when something goes wrong on your application you have to come to this folder logs, and take a look at these files to see what is going on. Which one is the better file to consitute in each occasion? Well, it depends, it depends on what happened in that moment. We are going to see several cases that we're going to come here to consult all these files. We're going to see it. In the next class we are going to explore the Eclipse environment too.

We are going to create a simple application and they're going to deploy on Tomcat. You're going to see all this. OK? That's all for now. Thank you very much. See you later.
