Galera, to implementando RMI em java e to com um probleminha aqui, tenho que passar dois vetores e mais o numero de elementos deles como parametro do metodo, mas quando passo ele como parametro da uma exception que não sei o que é.
import java.rmi.server.UnicastRemoteObject;  
import java.rmi.RemoteException;  
  
public class Calcular extends UnicastRemoteObject implements CalculoInterface  
{  
      
    public Calcular() throws RemoteException{   
        //super() is allways called  
    }   
      
    public String recebeDados(int L, double[] vetA, double[] vetB) {  
        double primSoma=0;  
        double segundaSoma=0;  
        double terceiraSoma=0;  
        double resultado = 0;         
        for(int i=0; i<L; i++){  
            primSoma += vetA<i>*vetB<i>;  
        }  
        for (int i=0;i<L;i++){  
            segundaSoma += Math.pow(vetA<i>,2);  
            terceiraSoma += Math.pow(vetB<i>,2);  
        }  
        resultado = primSoma/(Math.sqrt(segundaSoma+terceiraSoma));   
        return ("O valor da Correlação de Cosini é "+resultado);
