using primefaces extensions (inputNumber) - primefaces

Question

i'm new in primefaces word , and i need to use primefaces extensions (inputNumber)
in the XHTML file I add the taglib :
xmlns:pe="http://primefaces.org/ui/extensions"
when adding the jar :
primefaces-extensions-0.6.3;
I have an error : La ressource demandée n'est pas disponible.
When removing it, the application works but the inputNember doesn't show and I get this
error:
Warning: This page calls for XML namespace http://primefaces.org/ui/extensions declared with prefix pe but no taglibrary exists for that namespace.

Answer 1

To work with primefaces extensions i should add to the XHTML file the taglib:
xmlns:pe="http://primefaces.org/ui/extensions"
and to the lib folder two jars:
primefaces-extensions-0.6.3.jar
common-lang3.jar.
that is all.

Answer 2

If you are using maven for your dependencies, the required entry is
<dependency>
<groupId>org.primefaces.extensions</groupId>
<artifactId>primefaces-extensions</artifactId>
<version>0.6.3</version>
</dependency>
This will add the required dependencies for primefaces extensions.
If you are not using maven, then you should follow the Getting Started guide for "other users" and add all the necessary jars

For me, one maven dependencies is missing !
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.0</version>
</dependency>
Attention: currently "commons" is with S at end
At 2016.12.24, the version of extension can now be 6.0.0
<dependency>
<groupId>org.primefaces.extensions</groupId>
<artifactId>primefaces-extensions</artifactId>
<version>6.0.0</version>
</dependency>
Thanks to Rong Nguyen and Ghizlane La
Last remark
I have encouter some problems (error message in Chrome indicating that some ressources are missing) because the versions used for Primefaces and PrimefacesExtension end Commons-lang3 are not compatible !
But I have found that the following combination work correclty for me.
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.5</version>
</dependency>
<dependency>
<groupId>org.primefaces</groupId>
<artifactId>primefaces</artifactId>
<version>6.0</version>
</dependency>
<dependency>
<groupId>org.primefaces.extensions</groupId>
<artifactId>primefaces-extensions</artifactId>
<version>6.0.0</version>
</dependency>
I hope that will be useful for others :-)
