JDWP exit error AGENT_ERROR_TRANSPORT_INIT (197): no transport initialization [../../../src/share/back/debugInit.c:690]

Question

I am trying to run this configuration with JRebel:

Here is my conclusion:

Answer 1

Note the following launch option in your post.

 -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n 

There must be some other process busy on port 8787.

Answer 2

Port 8787 is already in use. If port 8787 is used by another application, you need to select a different port number in the run.bat file . For example, 18787

Answer 3

ERROR: transport error 202: communication failure: address already in use ERROR: JDWP Transport dt_socket could not be initialized, TRANSPORT_INIT (510) from "JAVA_OPTS: address = 8787" u set the address 8787

• find pid

  netstat -ap | grep 8787

kill theFindedPid

if u still gets pid "netstat -ap | grep 8787", there are child pids of theFindedPid 2. pstree -p and also pstree -p | grep theFindedPid to find if there are child pids from the FindedPid file

• find the group Pid pid ps x -o "% r% p% y% x% c"

• kill -TERM -groupPid

Answer 4

Usually this error occurs when the port is already in use. Based on my experience, this usually happens when the server has not started to successfully start the server in the process. If you use windows, you can check your task manager (Ctrl + Shift + Esc) and then search for the process "java.exe". Finish it and try starting the server again.

Answer 5

This problem occurs when the port required to start your server is already in use by some other application. Since the port number 8080 , which I used for my berth server, was already used, it gave me this error, so I just changed the port from 8080 to 7070 , and it worked for me.
