我想远程调试在Tomcat 7中运行的应用程序.Tomcat作为Win2008服务器上的服务运行.我将以下内容添加到Tomcat的Java配置面板中的Java选项中: -Xdebug -Xrunjdwp:transport=dt_socket,address=4711,server=y,suspend=n并在我的工作站和此端口的服务器上打开防火墙.但是当我在工作站上尝试从IntelliJ 9进行调试时,我收到一条错误消息Unable to open debugger port : java.net.ConnectException "Connection timed out: connect".jvm是备用的Sun/Oracle 64位JVM版本1.6.0_27.

我通过访问ManagementFactory.getRuntimeMXBean().getInputArguments()部署到Tomcat的应用程序并将结果记录到日志文件来验证命令行参数正在使用中.我通过Wireshark在我的工作站和服务器上验证了端口4711上的TCP请求是从我的电脑发送到达服务器的,但是没有答案.netstat -a在服务器上运行不会显示侦听此端口的进程.所以我假设Tomcat/JVM不会启动远程调试.

我有JaxWS Web服务客户端,多年来一直在Java 6中成功运行.现在,当Java升级到版本8时,我们在获取端口时会收到NullPointerException

java.lang.NullPointerException

我已经尝试使用Java 7版本1.7.0_80运行它并且它也可以工作,但Java 8的第一个版本会导致此异常.

我已经用这个打了很长时间了,所以如果有人能给我任何线索从哪里开始修复它会非常棒.

这是WSDL,我编辑了一点,因为它不是我的服务,但希望它足够了？
