how to transform a jsonarray into a string list in Nifi

[#1]

Hello,

i have a queryCassandra which generate a json like this one(the number of terms isn't fix):

{"results":[{"term":"term1"},{"term":"term2"}..]} 

Now, i want to get from this all the terms values separated by some separator in string format;

ex : term1,term2,term3

So i can pass this list as a string parameter for a java main program which i've alreat set.

(i only need the transformation, not the java program execution) Thank you !
