Hi, i am trying to get Processing to do an HTTP POST with some JSON bits to NIMBITS, so far i was not succesful in finding a correct method. Is there a library i should be using?

FYI Nimbits (Nimbits Manual) is a service similar to Pachube (Now cosm), i have a Processing sketch working already with Cosm using a library but couldn´t find a similar one for nimbits

My project is gathering Wireless Sensor Network data with Arduino+Xbee (working), sending it to Processing and dataloging on a PC (Working) and the final bit is to store the data on Cosm (working) and Nimbits (Not working!)

Thank you in advance for any help you guys can give me
