Define configuration file outside of the classpath
Here I describe the way I use to configure my applications. The main idea is to define a property file outside of the application, doing this, it is possible to deploy the same application in several environments (dev/test/prod) without any changes. First of all, the property file: net.classnotfound.app.jdbc.server=db-server net.classnotfound.app.jdbc.port=1521 net.classnotfound.app.jdbc.sid=xe net.classnotfound.app.jdbc.user=scott net.classnotfound.app.jdbc.password=koala The tips is… Continue reading Define configuration file outside of the classpath
Spring MyBatis configuration
Here I describe the project configuration to use MyBatis as ORM and benefit of the transactions management provided by Spring. For that, we have to add the MyBatis-Spring library to the basic MyBatis. First, the Maven POM is like: <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.2.3</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.1</version> </dependency> And now, the Spring configuration file… Continue reading Spring MyBatis configuration
Enable transactions on Informix DB

Spring Security with JSF 2 and custom login form
Here, I am integrating Spring Security with JSF 2 using a custom login form. First, the maven dependencies for Spring-Security (I consider that the JSF project is already set-up, if it is not the case, you can check here): <properties> … <spring.security.version>3.2.4.RELEASE</spring.security.version> </properties> … <!– Spring-Security dependencies –> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-core</artifactId> <version>${spring.security.version}</version> </dependency> <dependency> <groupId>org.springframework.security</groupId>… Continue reading Spring Security with JSF 2 and custom login form
