I have problems with getting arrays as input (or output) in bpel. I use Eclipse BPEL designer to design the process. the proces is simple: I just call one web-service. But the problem is that this web-service gets array as input. It means that the input value of the process must be array. how can I do it? Because when I use Assign "from" "to" I can't pass array throw process input. I just can pass only a String value. How can I change types of input/output values in process?
