我是用JB新建的EJBClient来测试的，这种情况是要写环境文件吧

Answer 2

在
Object objref = ctx.lookup("FundManagerHome");
这1句抛出的异常

Answer 3

prop.put(Context.PROVIDER_URL, "iiop://localhost:2809");一句改用t3试一试：prop.put(Context.PROVIDER_URL, "t3://localhost:2809");服务亲听端口应该为 2809

Answer 4

在
Object objref = ctx.lookup("FundManagerHome");
这1句抛出的异常假如你的Bean的名字叫FundMangerBean，那么上句话改成
Object objref = ctx.lookup("FundManagerBean");
试试
