Cannot find symbol error

BoyerMooreServer.java
import java.rmi.*;

public class BoyerMooreServer {
public static void main(String args[]) {
try {
BoyerMoore b= new BoyerMooreImpl("BoyerMooreServer");
Naming.rebind("rmi://localhost:1099/BoyerMooreService", b);
} catch (Exception e) {
System.out.println("Trouble: " + e);
}
}
}

I already have BoyerMoore.java and BoyerMooreImpl.java...
Its a client server program using RMI in java....
I m getting error again and again at this line in the above program....Don't know y.....

BoyerMoore b= new BoyerMooreImpl("BoyerMooreServer");

BoyerMooreImpl.java class as been extend the UnicastRemoteObject class or not & impliement the BoyerMoore.java class
it helps you i think so.

if problem is not solved then print the stracktrace of expection.

I have done that before but i m getting the error given below....

I have also compiled all the files and all got compiled except BoyerMooreServer.java...

$ javac BoyerMooreServer.java
BoyerMooreServer.java:6: cannot find symbol
symbol : constructor BoyerMooreImpl(java.lang.String)
location: class BoyerMooreImpl
BoyerMooreImpl b= new BoyerMooreImpl("BoyerMooreServer");
^
1 error

Error is at new operator...

Show us the constructor of the BoyerMooreImpl class that takes a String parameter ...

kind regards,

See? There is no constructor in that class that takes a single String as its parameter. Problem solved ...

kind regards,

Jos

So please tell me what shuld i do now...
i don't know what to insert and where to insert in the program...plese reply..

It's your code so you should know what to do: either create a constructor that takes a single String parameter or don't call it with such parameter and use the existing no-args constructor.

kind regards,

Jos

You've managed to write that much code and you don't know how to write a constructor that takes a String parameter?
Crikey...

There are more things in heaven and earth Tolls; the code could've come to the OP in mysterious ways ...

kindest regards,

Jos ;-)

Thanks jos...
Got it ...
I have excuted and got the result...
