Try this.
尝试这个。
- Set
suspend=y, just to make sure you got the JVM line right. This should stop the VM on startup until you connect. - If you're on Unix, bring up the terminal and try
telnet [host] [port]- this will quickly let you know if there's anything listening to that port on that host. - Make sure the connection properties in Eclipse are set correctly. Note that the port defaults to 8000.
- Use the IP address instead of the host name, to rule out DNS/hostfile problems.
- Set
suspend=y，只是为了确保你的 JVM 行正确。这应该会在启动时停止 VM，直到您连接为止。 - 如果您使用的是 Unix，请打开终端并尝试
telnet [host] [port]- 这将很快让您知道是否有任何东西在该主机上侦听该端口。 - 确保 Eclipse 中的连接属性设置正确。请注意，端口默认为 8000。
- 使用 IP 地址而不是主机名，以排除 DNS/主机文件问题。
Another way of starting the JVM that I use successfully is:
启动我成功使用的 JVM 的另一种方法是：
-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=y
