and java code is

import org.springframework.context.ApplicationContext;
import
org.springframework.context.support.FileSystemXmlApplicationContext;

import com.danga.MemCached.MemCachedClient;

public class MClient {

        public static void main(String[] args) {

                ApplicationContext ctx = new FileSystemXmlApplicationContext(
                                
"/WebRoot/WEB-INF/classes/config/application-context.xml");

                MemCachedClient mc = (MemCachedClient)
ctx.getBean("memcachedClient");
                for (int i = 0; i < 100; i++) {
                        // try{Thread.sleep(2000);}catch(Exception e){}
                        mc.set("key" + i, "value" + i);
                }
                try {
                        Thread.sleep(5000);
                } catch (Exception e) {
                }
                for (int i = 0; i < 100; i++) {
                        System.out.println("get " + i + " value " + 
mc.get("key" + i));
                }
        }

}

thanks for attention.
