  8. Hmm, it seems like your site ate my first comment (it was extremely long) so I guess I’ll just sum it up what I had written and say, I’m thoroughly enjoying your blog. I as well as an aspiring blog writer, but I’m still new to the whole thing. Do you have any recommendations for newbie blog writers? I’d appreciate it.

PrimeFaces Push with Atmosphere

PrimeFaces Push is based on Atmosphere to establish WebSocket communication in an easy way. Bellow I will share the configuration to be able to do such kind of communication.
1- Adding the PrimeFaces and Atmosphere to the pom.xml for Maven dependency. Also, I added the dependency of the Apache Commons Lang3 to use the StringEscapeUtils while sending the notification message.
<dependency> <groupId>org.atmosphere</groupId> <artifactId>atmosphere-runtime</artifactId> <version>2.1.7</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>3.4</version> </dependency> <dependency> <groupId>org.primefaces</groupId> <artifactId>primefaces</artifactId> <version>5.0</version> </dependency> 2- The web.xml configuration for the push servlet.

2- Click the Next button and then check "Create a simple project (skip archetype selection)".
3- Write the Group Id and the Artifact Id then select Packaging as WAR.
4- Click the Finish button to create the project with the bellow structure displayed in the Navigator view.
5- As you can see there is no deployment descriptor file (web.xml) as there is no WEB-INF folder. Also by checking on the Project Facets (select the project then ALT+ENTER then choose from the left menu Project Facets), we can see that the version of the Dynamic Web Module is 2.5 and the JavaServer Faces is not sele…

Adding MyBatis mapper files dynamically

I'm currently working in a project that we needed to implement such case. Assuming you are using MyBatis CDI in a EJB/CDI context, the bellow code will produce the MyBatis SqlSessionFactory for the MyBatis mapper files that are defined in a static way.

First, your Configuration.xml will only contain the database connection as bellow:
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <environments default="development"> <environment id="development"> <transactionManager type="JDBC"/> <dataSource type="UNPOOLED"> <property name="driver" value="oracle.jdbc.driver.OracleDriver"/> <property name="url" value="jdbc:oracle:thin:@<HOST&g…
