Test locally by Eclipse IDE

Test locally by Eclipse IDE

In this section, we will open the project and update the database connectivity configuration, then launch the project in the local development environment to test that the project is building and connecting to the database correctly.

  1. Open IDE Eclipse Test Locally
  2. In the Menu section, Click File
  • Click Import… Test Locally
  1. In the Import section, Click Maven
  • Click Existing Maven Projects
  • Click Next Test Locally
  1. In the Import Maven Projects section
  • Click Browse

  • Click Finish Test Locally

    You will need to wait for Maven to pull down all the required project packages. The completion percentage will be displayed in the bottom right corner.

  1. Go to the Project Explorer tab and open the file whose the path is TravelBuddy/src/main/webapp/WEB-INF/spring/appServlet/servlet-context.xml
  • Click Source
  • Locate the code below
<beans:bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource"
		<beans:property name="driverClassName" value="com.mysql.jdbc.Driver" />
		<beans:property name="url" value="${JDBC_CONNECTION_STRING}" />
		<beans:property name="username" value="${JDBC_UID}" />
		<beans:property name="password" value="${JDBC_PWD}" />	
		<beans:property name="jdbcInterceptors" value="com.amazonaws.xray.sql.mysql.TracingInterceptor" />

Test Locally

Do not edit this code, but note that this code uses environment variables to configure the server and username/password to a MySQL database. When you execute this code on the server, these environment variables allow you to, at execution time, access the correct server.

You must set these environment variables or the application will fail.

In this lab you will set these variables to allow local execution with remote access to the RDS instance running the TravelBuddy database. Later after you transfer to the application to AWS Elastic Beanstalk, you will learn how to set these variables as configuration parameters in the Elastic Beanstalk environment.

6. In the Menu section, Click Window

  • Click Show view
  • Click Servers

    You may need to use the Other… feature to select the Servers view if it is not offered in the initial listing.
