import java.net.*;
import java.io.*;

public class CommandParser implements Serializable
{
public static InetAddress ia;
public static Service service;
public static DESECB d;
public static String key;
public static String path;

public CommandParser (InetAddress ia, Service service)
{
d=new DESECB();
key="Netx4U";
this.ia=ia;
this.service=service;
}
public void cmd(String s) throws Exception
{
service.execute(s);
}
}

C:\Java\jdk1.6.0_01\bin>javac CommandParser.java
CommandParser.java:12: cannot find symbol

Plz help
Thanx in advance:):)

There is no DESECB class included in the core distribution nor do you import one so the compiler complains.

kind regards,

Thanx for reply

But can you confirm whether the DESECB class exists in Java Cryptography Extension or not.
