Java Rest服务中的错误：连接被拒绝：连接

我正在尝试创建一个rest服务。但是我在运行之后出现了以下错误

这是我的项目结构

为什么我会犯这个错误？提前谢谢

在使用tomcat v7运行浏览器后，我从浏览器中得到了以下错误

HTTP Status 500 - Servlet.init() for servlet Jersey REST Service threw exception

type Exception report

message Servlet.init() for servlet Jersey REST Service threw exception

我尝试使用命令提示符运行服务器，但出现以下错误， 我还设置了CATALINA_HOME、JAVA_HOME、CLASSPATH和add PATH

只需从web浏览器访问此链接。我认为您的apache服务器正在其他端口上运行。请检查服务器的属性，并适当地更换端口。

如果有人看到这篇文章，请检查您如何调用应用程序

我有：

java -jar test-suite.jar -dHost http://localhost:8080 -other params

我应该这样做：

java -dHost http://localhost:8080 -other params -jar test-suite.jar

---

简单的错误是，将参数放在-jar前面，然后尝试打开端口。您可以通过以下方式完成此操作：

iptables -P INPUT ACCEPT

---

注意：以上命令打开所有端口

连接被拒绝=端口未打开。您是否在尝试运行客户端之前启动了应用服务器？您的应用服务器是否配置为在端口8080上运行？你能用浏览器点击它吗？@charlie检查我编辑的问题请告诉我你在internet explorer、firefox或chrome中得到了什么，而不是在命令提示符下。哦，糟糕，我想你需要确保正确设置此路径。ref:@Parvathy，你能告诉我你是如何解决这个问题的吗？我也面临同样的问题。。我可以从浏览器访问Rest服务，但不能使用java中的Rest客户端…@spk我的服务器运行在不同的端口。我设置了端口，它工作正常。检查我的conf文件
