How to add DATABASE access in Dynamic Web Project ?

We will get such structure :

Add DATABSE in Dynamic Web Projet

Add DATABSE in Dynamic Web Projet

1. Create in your WEB_ROOT these folders: WEB-INF/database
2. Create file “datapase.properties” :

1
2
3
4
5
jdbc.driverClassName=org.postgresql.Driver
jdbc.url=jdbc\:postgresql\://109.197.1.1\:5433/yourDB
jdbc.username=yourLogin
jdbc.password=yourPWD
jdbc.showSql=true

3. Create DataSource.xml file – it contains bean “dataSource” and gets value from “datapase.properties” file :

EclipseLink ~ where is it in MAVEN ?

Where can I find ECLIPSELINK using MAVEN?
1. Configuring your pom.xml

Add Repository
<repository>
   <id>EclipseLink</id>
   <url>http://download.eclipse.org/rt/eclipselink/maven.repo</url>
</repository>

Add dependencies :

<dependency>\
   <groupId>org.eclipse.persistence</groupId>
   <artifactId>{artifact}</artifactId>
   <version>{version}</version>
   <scope>compile</scope>
</dependency>

2. Add eclipselink-wrapper (not fron GlassFish!)

And be Happy!
