Copy of Pleading?

Copy of Pleading? Khine: I've moved out to AZ from Virginia last year after I had filed for divorce. My ex husband has agreed to return service of acceptance but had not keep his word.
This has been since September last year and I cannot locate him as he works as a contractor in Iraq. (Perfect excuse not to face his responsibilities!)
I have been advised by the court to move on with the case. The procedure according to Fairfax circuit court in VA, states that I must include a "copy of pleading" in order to proceed the case by means of service by publication. What is this?
I have downloaded other papers required for service by publication but do not understand what 'copy of pleading' means.
I am on my own as I do not have means to hire a lawyer. Please help!
