I recently had to solve this too. What I did is:

1) I created class that implements java.sql.Array (it is sufficient to 
implement getArray(), getBaseType(), getBaseTypeName() and toString(), 
for details see Java API docs) + I added one extra method, 
setArray(Class componentType, Object[] array), where componentType is 
component type of the array, which I use for setting the array value 
into the array

2) Then I use this code to set the array:

                    final MyArray array = new MyArray();
                    array.setArray(componentType, arrayValue);
                    pstm.setArray(index, array);
