Message Error: unreported exception java.rmi.RemoteException; must be caugh

Posted: Nov 8, 2002 6:45 AM

I am developing a work of Distributed Systems using the resource RMI. When I compile my file java presents the following message:

D:\MYDOCU~1\Unicsul\TOPICO~1\SISTDI~1\Java>javac cadServer.java
cadServer.java:5: unreported exception java.rmi.RemoteException; must be caught
or declared to be thrown
public class cadServer extends UnicastRemoteObject implements cadInterface
^
1 error

Here this the code source.. If they could help me I will thank a lot.

import java.rmi.server.*;
import java.rmi.*;
import java.sql.*;

public class cadServer extends UnicastRemoteObject implements cadInterface
{
public String insRegistro(String rgm, String nome, String endereco, String cidade, String estado, String cep, String email)
throws RemoteException
{
Connection con;
Statement stmt;
String url = "jdbc:odbc:Cadastro";
String ins = ("insert into tb_Alunos values ('"+rgm+"','"+nome+"','"+endereco+"','"+cidade+"','"+estado+"','"+cep+"','"+ema il+"')");

try
{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
}

catch(java.lang.ClassNotFoundException e)
{
System.err.print("ClassNotFoundException:");
System.err.println(e.getMessage());
}

try
{
con = DriverManager.getConnection(url,"","");
stmt = con.createStatement();
stmt.executeUpdate(ins);

}

catch(SQLException ex)
{
System.err.println("SQLException: " + ex.getMessage());
}
return(null);
}

public static void main (String a[])
{
try
{
cadServer x = new cadServer();
Naming.rebind ("rmi://127.0.0.1:1099/rmiCadastro", x);
}
catch (Exception re)
{
System.err.println("Remote Exception: " + re.getMessage());
}
}
}

Add a constructor that throws RemoteException

public cadServer() throws RemoteException{

}

Also

String ins = ("insert into tb_Alunos values ('"+rgm+"','"+nome+"','"+endereco+"','"+cidade+"','"+estado+"','"+cep+"','"+ema il+"')");

Where does ema come from? And you can't have a space between it and il.
