Simply uncompress it, and you'll have an atmosphere able to commence constructing. glance it at determine four. 1. determine four. 1 OpenXava distribution content material As you notice, OpenXava distribution contains Tomcat and an Eclipse workspace, all configured and able to use. Let's begin to paintings. Create the venture making a new OpenXava undertaking is straightforward. simply create a typical Java undertaking with Eclipse, after which execute an ant goal. begin your Eclipse and open the OpenXava workspace with it (File > swap Workspace). First, you want to create a brand new Java undertaking. click the button for making a new Java venture (figure four. 2). determine four. 2 Button for making a new Java venture in Eclipse Then a wizard will look. simply sort the venture identify, Invoicing, and click on the end button (figure four. 3). determine four. three New Java venture After this step you've gotten an empty Java venture named Invoicing (figure four. 4). determine four. four Empty Java venture Now you need to convert it into an OpenXava venture. visit the CreateNewProject. xml dossier of the OpenXavaTemplate undertaking, and run it as an ant construct (figure four. 5). determine four. five operating CreateNewProject ant construct Now you should kind the venture identify. simply style “Invoicing” and click on okay (figure four. 6). determine four. 6 After ant execution you get an OpenXava venture Wait a couple of moment till the ant construct finishes. Then choose Invoicing venture on your Eclipse, and press F5 to refresh it. Now you've an entire OpenXava undertaking there. we'll configure the Tomcat within your Eclipse to exploit it as a platform for working your software. four. three. three Configuring Tomcat inside of Eclipse beginning Tomcat from Eclipse has numerous benefits like you can debug, see the log messages and lines inside of Eclipse, move from hint to code in a click on, and so on. including Tomcat as a runtime server to Eclipse visit the Eclipse alternative menu home windows > personal tastes > Server > Runtime Environments. this can convey you the wizard in determine four. 7. determine four. 7 Wizard so as to add Tomcat as server runtime to Eclipse including a Tomcat server to Eclipse After following the guideline in determine four. 7, you've gotten Tomcat additional in your Eclipse as a runtime setting.
