In this project, Java and XML file contains the below code to display Hello World message. The folder can be anything, here we have created a test folder.Īfter creating all the above files, our project should look like the below. Build is a default name but we can set other name also.Ĭreate a folder to organize compiled Java class files. Create a Java ProjectĬreate a project by selecting Java project from the File menu and provide it’s name.Ĭreate a Java class by providing it’s name Hello, see the below example.Ĭreate an XML File by providing it’s name build. That copies the JARs to the appropriate location.To create a simple hello world project, we are using Eclipse IDE and the project require the below steps. This Ant target will copy JARs recursively fromĪttribute so all JARs end up in the same directory.

This ensures that your app is using the same versions of these interfaces as the ones included in the SDK, even if you upgrade the SDK at a later date.ĭirectory, they cannot be in subdirectories. However, it's useful to make copying these JARs part of the build process. You could copy these JARs into the WAR manually. If your application uses the JDO or JPA interfaces to the App Engine datastore, the app must include the JDO/JPA implementation in App Engine checks for classes from this JAR to determine which version of the API your app is using. Represents a version number of the API and SDK), a JAR included with the SDK, in the directory Tag to define a class path containing these JARs: Additionally, the JARs in the SDK'sĪnd add the following lines above the closing The application can access classes from JARs added to this directory. When you compile your classes, the Java class path must contain the JARs for the App Engine API, and any other JARs you may have added to your project'sĭirectory (such as the DataNucleus JDO/JPA JARs).
We will use several of these macros later. (Paths are relative to the location of theĮlement loads a set of Ant macros for App Engine development, included in the App Engine Java SDK.

The file defines two Ant properties, which we will use when we define targets and paths later. This build file doesn't do anything yet: it doesn't contain a "target" with instructions to perform tasks. (Within the Ant file itself, paths using forward slashes If you are using Windows, change the forward slashes To create this directory structure from the command prompt, use the following commands. The complete project directory should look like this: You will create other files for the WAR directly in the The build process will compile the source code, and put the compiled Java bytecode in the appropriate location under

(WAR archive files are not yet supported by the SDK.)įor these instructions, we will put all project-related files in a single directory namedįor Java source code and a subdirectory namedįor the finished application files. Standard layout for Java web applications. , your App Engine project must produce a directory structure using the If you do not already have Ant installed on your system, visitĬommand is on your command path, you can run the following command to verify that it works, and see which version is installed: Upgrading to the latest (experimental) versions requires changes to theįile that are not documented on this page. , please note that this article applies to JDO version 2.3 and JPA version 1.0. To skip the description and go directly to the complete file for copying and pasting, see This article describes an Ant build file useful for most projects. The Java SDK includes a set of Ant macros to perform common App Engine development tasks, including starting the development server and uploading the app to App Engine. Makes it easy to manage your project from the command line, or from other IDEs that work with Ant. , you'll probably want some other way to manage the process of building and testing your App Engine application.
