json output webservice

Hi,

I would like to run a protocol from a third part program and to have a json response as the output, reusable in my program

I tried to run this protocol given in example : /Web Services/Examples/Generic/Shakespeare Search.

I've just added "&_format=json" at the end of the Protocol link :

http://server:port/auth/launchjob?_compat=1&_protocol=Protocols\\Web%20Services\\Examples\\Generic\\Shakespeare%20Search&Line%20Delimiter=&Maximum=100&Search%20For=creeps&Search%20For=tale

&_format=json

The output seems to be not valid for Firefox :

SyntaxError:JSON.parse: bad control character in string literal at line 1 column 12 of the JSON data

{"Hits":["[

{"Title":"The Tragedy of Macbeth","Act":5,"Scene":"SCENE V.  Dunsinane. Within the castle.","Speaker":"MACBETH","Speech":["She should have died hereafter;","There would have been a time for such a word.","To-morrow, and to-morrow, and to-morrow,","Creeps in this petty pace from day to day","To the last syllable of recorded time,","And all our yesterdays have lighted fools","The way to dusty death. Out, out, brief candle!","Life's but a walking shadow, a poor player","That struts and frets his hour upon the stage","And then is heard no more: it is a tale","Told by an idiot, full of sound and fury,","Signifying nothing.","Thou comest to use thy tongue; thy story quickly."]}

]"]}

What can I do to correct it ?

Thanks

Christophe
