我需要帮助！
到目前为止我试过这个......
这是我的ejb代码：
package ejb30.session;
import java.util.*;
import javax.ejb.Stateless;
//@Stateless
@Stateless(mappedName="Time")
public class TimeServiceBean implements TimeService {
public String getTime() {
Formatter fmt = new Formatter();
Calendar cal = Calendar.getInstance();
fmt.format("%tr", cal);
return fmt.toString();
}
}
这是我的ejb客户端代码：
package ejb30.client;
import javax.naming.*;
import ejb30.session.*;
public class Client {
public static void main(String args[]) throws Exception {
InitialContext ctx = new InitialContext();
// glassfish version:
// TimeService timeService = (TimeService) ctx.lookup("ejb30.session.TimeService");
// weblogic version:
TimeService timeService = (TimeService) ctx.lookup("Time#ejb30.session.TimeService");
String time = timeService.getTime();
System.out.println("Time is: " + time);
}
}
我正在使用weblogic 12.2并启动了我的weblogic服务器： 当我调用客户端代码时，我收到以下错误：
run-client:
