Access JSF and Primefaces version numbers programmatically

Question

I use PrimeFaces 3.5.x and Mojarra JSF 2.1.x I would like to access and show the versions of both libraries programmatically.

I use the versions as maven2 properties

Answer 1

If you need to get the Version on runtime, there will not be any instance of RequestContext. Therefore you could use the ImplementationVersion of the package:

Package.getPackage("org.primefaces").getImplementationVersion()

If the package cannot be resolved, you can try to resolve the version via PrimeFaces class:

PrimeFaces.class.getPackage().getImplementationVersion()
