bt im gettin the foll errors

FileImpl.java:30: '.class' expected
return buffer[];
^

here is my code
import java.io.*;
import java.rmi.*;
import java.rmi.server.UnicastRemoteObject;

public class FileImpl extends UnicastRemoteObject
implements FileInterface {

private String name;

public FileImpl(String s) throws RemoteException{
super();
name = s;

}

public byte[] downloadFile(){
try {

File dir=new File("C:\\Program Files\\Java\\jdk1.5.0_07\\bin\\a");
File x[]=dir.listFiles();
for (int i =0;i<x.length;i++){
File file = x[i];
byte buffer[] = new byte[(int)file.length()];
BufferedInputStream input = new
BufferedInputStream(new FileInputStream(x[i].getName()));
input.read(buffer,0,buffer.length);
input.close();

}
return buffer[];
}
catch(Exception e){
System.out.println("FileImpl: "+e.getMessage());
e.printStackTrace();
return(null);
}
}
}

This line is problem:

return buffer[];

Without going into your logic and purpose of this
here is method without errors that returns byte array - buffer:

public byte[] downloadFile(){
		
		[B]byte buffer[] = null;[/B]
		try {

			File dir=new File("C:\\Program Files\\Java\\jdk1.5.0_07\\bin\\a");
			
			File x[]=dir.listFiles();
			
			for (int i = 0; i<x.length; i++){
				File file = x[i];
				
				[B]buffer[/B] = new byte[(int)file.length()];
				BufferedInputStream input = new BufferedInputStream(new FileInputStream(x[i].getName()));
				input.read(buffer,0,buffer.length);
				input.close();

			}
			[B]return buffer;[/B]
		} 
		catch(Exception e){
			System.out.println("FileImpl: "+e.getMessage());
			e.printStackTrace();
			return(null);
		}
	}

cheers!
