这个是远程接口package ejb;
import javax.ejb.Remote;
@Remote
public interface IntegralRemote {
public double integral( double a,double b);
}
这个是远程接口的实现package ejb;
import javax.ejb.Remote;
@Remote
public interface IntegralRemote {
public double integral( double a,double b);
}
jsp 中的调用 <%
try{
Context ic=new InitialContext();
Object obj=ic.lookup("Integral/remote"); //Object obj=ic.lookup("ejb/Integral");
//IntegralHome home=(IntegralHome)PortableRemoteObject.narrow(obj,IntegralHome.class);
IntegralRemote h=(IntegralRemote)obj;//Integral h=home.create();
double a=Double.parseDouble(request.getParameter("a"));
double b=Double.parseDouble(request.getParameter("b"));
out.println("<h3>"+h.integral(a,b)+"</h3>");
}catch(Exception ex)
{
ex.printStackTrace(response.getWriter());
}
%>
错误 是在 jsp部署的时候 出现了 *** CONTEXTS IN ERROR: Name -> Error

是大神 。。。

ejb.Integral 这个bean没有指定接口
你给的代码里面没有这个类
你给的JSP里面提到了这个类，但是被注释了..
so
个人判断应该是垃圾代码没有清理干净...全文检索一下
