Yes, I had access to the code, the problem is that the weblogic version that I'm using is 10.0 and it doesn't have the checkbox to disable the wrapper types, and with the code solution, I can't put the weblogic class into my project because conflicts with other libraries (hibernate).
I found this solution:
java.sql.Array array = (java.sql.Array) result.get("ARRAY");
Object arrayStructs[] = (Object[]) array.getArray();
//and then just cast to oracle.sql.STRUCT
