Application Module- Exposed services ADF 11g

Question

Hi,
I had tried to expose few methods in AM so that I can invoke them from BPEL.
As per my understanding , only the methods which return primitive type like int,long (for eg : int getCount(int a,int b){}) are only allowed to be exposed.
When I tried to expose methods that return any arraytype say int[], long[],String[] or Arraylist ,I could not find those methods in the available Service Custom methods in the Service Interface tab of ADF-AM.Also, I got few warnings that those methods with return type as [] will not be supported.
Is there any workaround for this ?How can we expose methods that return arrays or arraylist in adf-AM.
Any pointers would help.
thanks
SS

Only types that implement the java.io.Serializable interface are allowed in the method signature.
