Thank you for your kind support in advance.

Hi Lakshman,

I don't think that there ever was an Orbeon Forms 3.4 release. Are you maybe referring to Orbeon Forms 4.4? Anyhow, it is hard to guess based on this error message. I would check if you have a reference in your `properties-local.xml` to a file that Orbeon Forms is unable to find. You'll let us know if this helps.
