ejb客户端通过JNDI访问服务器报错 Connection refused: connect

ejb客户端通过JNDI访问服务器报错 javax.naming.ServiceUnavailableException: Connection refused: connect 客户端代码为： ``` InitialContext ctx = new InitialContext(); FirstEjb ejb = (FirstEjb)ctx.lookup("FirstEjbBean/remote"); String s = ejb.saySomething("HelloWorld"); System.out.println(s); ``` 具体错误为：

测试报错，Connection refused: connect，求解？

初学者关于 java.net.ConnectException: Connection refused: connect的问题？

javase初学者一名，在看到head first java的网络联机这一节中遇到了问题。 用eclipse测试该语句时报错： java.net.ConnectException: Connection refused: connect ``` Socket s=new Socket("127.0.0.1",5000); ``` 搜索了一些处理 java.net.ConnectException: Connection refused: connect的方法，大多都是说Tomcat的问题，刚刚接触java不久对这些javaweb的东西一无所知，看了一部分帖子后，我猜测可能是我没有Tomcat的原因，我尝试了下在eclipse上装了server，并且载入了Tomcat，但是启动服务器失败了。 所以我想问这里的 ``` Socket s=new Socket("127.0.0.1",5000); ``` 到底是什么原因导致了connection refused。是否是因为与网络相关就必须要载入服务器，还是别的原因。《head frist java》并没有说需要载入服务器，Tomcat什么的操作。 以下是错误提示  程序代码 ``` import java.io.*; import java.net.*; public class DailyAdviceClient { public void go () { try { Socket s=new Socket("127.0.0.1",5000); InputStreamReader streamReader=new InputStreamReader(s.getInputStream()); BufferedReader reader=new BufferedReader(streamReader); String advice=reader.readLine(); System.out.println("Today you should "+advice); }catch(IOException ex) { ex.printStackTrace(); } } public static void main(String[] args) { DailyAdviceClient client =new DailyAdviceClient(); client.go(); } } ```

连接hbase Connection refused: no further information

server环境: 在virtualbox里安装了ubuntu，然后装了了hadoop2.7.5,hbase1.3.1，然后hadoop和hbase的环境都配置好了 启动了hbase，然后本机里通过scala访问虚拟机里的hbase时，connection能获取到，但是在执行tableExists时，卡一会后就报超时了，client的代码和server的配置如： server配置(其中zookeeper用的hbase自己管理的)： hbase-site.xml  client的代码： ``` class HbaseUtil { def GetHbaseConfiguration(ip:String):Unit={ var conf = HBaseConfiguration.create;

tomcat:Connection refused: connect什么原因

我的tomcat.startup.bat后，客户端同时启动1000个以上线程去请求它时，开始运行会有 java.net.ConnectException: Connection refused: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(Unknown Source) at java.net.PlainSocketImpl.connectToAddress(Unknown Source) at java.net.PlainSocketImpl.connect(Unknown Source) at java.net.SocksSocketImpl.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.<init>(Unknown Source) at java.net.Socket.<init>(Unknown Source) 抛出，大家帮分析下是什么原因呢？ 我的server.xml中设置maxThreads="500" acceptCount="500"

（已解决）紧急求助！springboot启动服务，提示： java.net.ConnectException: Connection refused: connect

## 这个服务昨晚还可以运行的，今早启动后， 一开始提示：could not be registered. A bean with that name has already been 根据网友的说法，我设置了：_allow-bean-definition-overriding: true _ ## 然后就开始报这个错了，现在把上面这个配置注释掉也不行。。。 请大神指教！ +++  +++ ``` com.sun.jersey.api.client.ClientHandlerException:

关于CXF的client调用server,出现Connection refused: connect

环境描述 jdk7 cxf.version = 3.0.0 Spring.version = 3.2.4 图片详细描述:http://www.oschina.net/question/1027522_2138367#answers 出的问题: 以前没设置防火墙，访问http://IP/services/服务名，请求没有问题 现在有设置防火墙了，不能IP访问，只能通过域名，http://yx.hello.comIP/services/服务名 然后就经常Connection refused: connect 请问是哪个环节需要改进？公司明确了就是要通过网址调用，求各位大神解救啊

java网络编程错误java.net.ConnectException: Connection refused: connect求教

刚开始学习java网络编程，在书上看到一段代码，就动手试一下，结果出现下面错误： java.net.ConnectException: Connection refused: connect 源代码如下： import java.io.*; import java.net.*; class lx01 { public static void main(String[] args) { String host = "localhost"; BufferedReader br = null; PrintWriter pw = null; Socket s = null; try { s = new Socket(host, 10000); InputStreamReader isr; isr = new InputStreamReader(s.getInputStream()); br = new BufferedReader(isr); pw = new PrintWriter(s.getOutputStream(), true); pw.println("DATE"); System.out.println(br.readLine()); pw.println("PAUSE"); pw.println("DOW"); System.out.println(br.readLine()); pw.println("DOM"); System.out.println(br.readLine()); pw.println("DOY"); System.out.println(br.readLine()); } catch (IOException e) { System.out.println(e.toString()); } finally { try { if (br != null) br.close(); if (pw != null) pw.close(); if (s != null) s.close(); } catch (IOException e) { } } } } 求教各位大神这是啥原因，如何解决？

android连接电脑tomcat服务器报错 connection refused

在电脑上部署了tomcat的服务器，电脑ip地址是192.168.191.1，这是android应用里请求的url地址：String URL = "http://192.168.191.1:8080/system_web/server";通过 HttpResponse httpResponse=httpClient.execute(httpRequest);这种方法请求连接。 结果报错connection to 192.168.191.1 refused。我的手机连的是电脑的wifi，而且在手机的浏览器通过访问http://192.168.191.1:8080/system_web/server是可以的，就是android程序里面报错。到底是哪里的问题啊，弄了一下午了。

ngnix+fastcgi+python服务器每隔20几分钟就报connection refused

正在搭建一个fake server,要求每秒钟支持7000个并发。server采用nginx/fastcgi/flup搭建，用spawn-fastcgi来管理fastcgi进程，后台的应用程序很简单，就是返回固定的一串字符串，用python写的。用jmeter打流量测试，发现开始20几分钟server运行很好，后面就会有断断续续的error产生，刚开始以为是应用程序反映不过来，后来就将fastcgi进程加到200，可还是会有这样的情况发生。nginx的error.log： 2011/09/30 23:47:54 [error] 31160#0: *35 connect() failed (111: Connection refused) while connecting to upstream, client: xx.xx.xx.xx, server: domain.com, request: "GET /dev/ HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "domain.com 搞了很久，还是没解决，求那位大神指点迷津，感激涕零！

FileZilla连接失败，connection refused

本人Linux小白，望轻喷 我用visualbox配置了一台Ubuntu16.04的虚拟机，今天想用FileZilla传一些文件给虚拟机，发现连接失败。 错误信息是： ``` 状态: 正在连接 192.168.3.5... 响应: fzSftp started, protocol_version=5 命令: open "jeloys@192.168.3.5" 22 错误: Network error: Connection refused 错误: 无法连接到服务器 ``` 然后尝试了网上所说的开启ssh 和 sshd 没有用，防火墙已经关闭，iptables也已经为ssh设置好了。然后在虚拟机上使用 ``` root@jeloys-VirtualBox:~# ssh 192.168.3.4 ``` 提示： ``` ssh: connect to host 192.168.3.4 port 22: Connection refused ``` 注：宿主ip为192.168.3.4；虚拟机IP为192.168.3.5；虚拟机网络为桥接模式。 求各位大佬答疑解惑~
