Remote debug

[Luca Merolla <lu...@gmail.com>]

Hi,

I have configured the remote debug for TomEE by adding the following line
at the beginning of catalina.sh. Thanks to this I'm able to connect
remotely with Eclipse debugger.

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

Is it the correct way to do it? I'm asking because since then, when I try
to shutdown the server, I get the following output.

ERROR: transport error 202: bind failed: Address already in use
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized
[../../../src/share/back/debugInit.c:690]
FATAL ERROR in native method: JDWP No transports initialized,
jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)
Aborted (core dumped)

I don't know maybe it is related to the other issue I'm having with
Infinispan that prevents to stop the server, but before this JAVA_OPTS I
was not getting this error.

Hi,

maybe the port is already used (i had it in such a case)

we commonly use it with the maven plugin. Using <debug>true</debug> or
-Dtomee-plugin.debug=true does the same (on port 5005 by default)

BTW with catalina.sh/bat script you can export JPDA_ADDRESS=<port> and
JPDA_SUSPEND=y to debug remotely

We also used manual specification port and other options, however found that
if we specify as you did - "JAVA_OPTS="-Xdebug 
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8787" " we have
some strange Tomcat crashes on shutdown.
We found that adding "jpda" startup option works much better

$TOMEE_HOME/bin/startup.sh:

substitute last line

exec "$PRGDIR"/"$EXECUTABLE" start "$@
with
exec "$PRGDIR"/"$EXECUTABLE" *jpda* start "$@

Regards,
Alex
