Getting started with Prime faces 2

Prime faces is an amazing JSF framework from Cagatay Civici ( Its wonderful because it is easy to use, minimal dependencies, has probably the widest set of controls among all JSF frameworks, easy to integrate with Spring (including Spring Security) , Java EE EJBs, and last but not the least mobile UI support. So I decided to give Prime faces a try, before selecting it to use in my projects.

Step 1 – Create Maven 2 project

As a first step to integrating Prime faces, create a Maven 2 project in Eclipse. You will need to select ‘maven-archetype-webapp’.

Step 2 – Add repositories and dependencies in pom.xml

I will be using Prime faces 2 with JSF 2 on Tomcat 6. Since the dependencies for Prime Faces and JSF 2 (JSF 2.0.3 is required) are available on different repositories, I will add them to my pom file first. The listing below shows my pom.xml

<project xmlns="" xmlns:xsi=""
<name>hermesconsole Maven Webapp</name>

<name>Prime Technology Maven Repository</name>
<name> Repository for Maven</name>



Step 3 – Change web.xml

Add the JSF faces servlet in the web.xml file.

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xsi:schemaLocation="" >


<servlet-name>Faces Servlet</servlet-name>

<servlet-name>Faces Servlet</servlet-name>


Step 4 – Add a simple xhtml file – home.xhtml

Now let us see Prime faces in action, by adding a simple JSF snippet with 1 control from this library.

<html xmlns=""

<f:view contentType="text/html">

<title>Hermes Console - Trying PrimeFaces</title>


<p:commandButton value="Ajax Submit" />



Step 5 – Build and deloy

Now that we are done, the next step is to build and create the war file and deploy it in Tomcat 6. Then point your browser to - http://localhost:8080/hermesconsole/home.jsf

You will see the following command button on your browser:

  1. I am using the setup as you, JSF2.0 + Tomcat 6.0.18, but the funny thing is, I just create a test web app with using Component "spinner", on the webpage,
    However, the two Arrow buttons they are not displayed. Why?
    Server logs has shown no any error/warning message.

    could you please contact with me on email thanks.

  2. java.lang.ClassNotFoundException: javax.faces.webapp.FacesServlet

Why do you need Spring Cloud Config server?

Last month I wrote a primer on concepts around 12 factor app. Before getting into the details of the Spring Cloud Config Server, I must refresh on the principle #3 from the list presented in that post.

3 – ConfigurationStore config in the environments
Configuration information must be separate from the source code. This may seem so obvious, but often we are guilty of leaving critical configuration parameters in the scattered in the code. Instead, applications should have environment specific configuration files. The sensitive information like database password or API key should be stored in these environment configuration files in encrypted format.
 The key takeaways from this postulate for a cloud-native microservices application are:
Do not store configuration as part of the deployable unit (in the case of lead microservice - inside the jar or war if you are still deploying war like the good old days). Instead, store it in an external location and make it easily accessible during run-…

Upgrading Lead Microservice - Use MariaDB and Flyway with Spring Boot

So far I have been using an in-memory H2 database or Mockito for testing the lead microservice. To make the transition towards using the Spring Cloud Config server, I need to upgrade the micro-application to use MariaDB. I will be adding the configuration in the application.yml  the file which in the subsequent post will move over to the config server store. I will also be using Flyway to make it easy to maintain the database schema changes in future. I will use this post to introduce Flyway in the mix. Spring Boot also provides first class integration with Flyway. I am using Flyway as its really quick and easy to get started, minimal learning curve (no DSL) and I am comfortable with it having used it in the past.


MariaDB 10 is installedBasic familiarity with FlywayHeidi SQL client is installed.
Step 1 - Update build.gradle to include the MariaDB JDBC and Flyway dependencies.
Do not forget to do a Gradle refresh on your IDE (I am using STS 3.8.4 on Java 8)

How to implement Cache Aside Pattern with Spring?

ProblemYou want to boost application performance by loading data from a cache and prevent the network trip to the persistent store (and also the query execution). This can be achieved by loading data from a cache. However, you want to load data on demand or lazily. Also, you want the application to control the cache data management – loading, eviction, and retrieval. Forces Improve performance by loading data from cache lazily.Application code controls cache data management.The underlying caching system does not provide read-through, write-through/write-behind strategies (strange really ??).
Solution Use cache aside design pattern to solve the problems outlined above. This is also one of many caching patterns/strategies. I believe it is named in this because aside from managing the data store, application code is responsible for managing the cache also.
Let's now try to understand how this caching technique works and then explore how it solves the problems.
ReadCache MissThe applic…
