CDF service from webMathematica

Suppose I enter the following (edited) piece of code in Mathematica.

manip = Manipulate[x, {x, 0, 1}];
nb = Developer`UseFrontEnd[
    CreateDocument[manip, ShowCellBracket -> False, 
    Visible -> False]];
nbTest = ExportString[nb, "NB"] =!= $Failed;
cdfTest = ExportString[nb, "CDF"] =!= $Failed;
version = First[StringSplit[SystemInformation["Kernel", "ReleaseID"]]];
{{nbTest, cdfTest},version}

I find that both nbTest and cdfTest are True. If I run the same command from webMathematica, nbTest is True and cdfTest is False. You can see this result here:

You can see the code that generates this result here:

I searched the webMathematica security configuration to find a way to enable CDF export, but did not find any. Does anyone know how to do this? Of course, this may be prohibited in this context intentionally.
