Hi Ofri,
Thanks for your reply.
We follow the instructions, and we can see the similar information about the opened debug port, that is, " [INFO] Listening for transport dt_socket at address: 8000". My understanding is compiler is okay and the debug port is available.
But, when I remote access to this host via Eclipse, the connection abort immediately. Some difference after compare with the instruction is, our IDE is installed on a windows OS and build env is on a linux OS, they are different physical machine, this shouldn't be the root cause in my opinion, remote debug from a remote server is make sense always. Any good suggestion? Thanks a lot!
Here is some error message I get after the connection is aborted.

> * after activating the webadmin on the browser via the gwt tool, be patient - it
