Custom component help in 4.9 Binary

Hi all,

I have a need in customizing existing form control like currency, state etc. While exploring i found the below link.

http://wiki.orbeon.com/forms/doc/developer-guide/xbl-components-guide#TOC-Getting-started

I am struck with below and need assistance.

a) When i look at my deployment i don't see any xbl file in my deployed orbeon.war.
b) as per the above document, i dont find orbeon-resources-private.jar in the downloaded binary distribution.

I am looking at a tutorial which illustrates the step for creating new / altering existing components.

Need your help in this regard.

Thanks & Regards,
Vishnu L
