How to install PrimeFaces Extensions in a PrimeFaces project

I was looking to install PrimeFaces Extensions into my PrimeFaces project, but I failed to find any website that mention how PrimeFaces Extensions install into a PrimeFaces project.

Thus, I have to try and error by myself. 

First, I opened up my PrimeFaces project that previously created with JBoss Tools. 

Then I copied the primefaces-extensions-0.6.2.jar into my PrimeFaces project and start the Tomcat.

Unfortunately, the application failed to start and showing the following error.

Caused by: java.lang.ClassNotFoundException: org.apache.commons.lang3.StringEscapeUtils
 at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1714)

It's required me to add in commons-lang3-3.1.jar into the project and restart again.

this time I was successfully start the Tomcat server, and tested the PrimeFaces Extensions with the following code.

<pe:inputNumber id="input2" value="#{testBean.numberValue}"
                symbol=" CHF" symbolPosition="s"
                decimalSeparator="," thousandSeparator=".">
    <p:ajax event="blur" />
</pe:inputNumber>

Output:

Conclusion:

copy the following jar into the existing PrimeFaces project and test the PrimeFaces Extensions again
1. primefaces-extensions-0.6.2.jar
2. commons-lang3-3.1.jar

It should works!
