Debugging Smartfox on MAC/intelliJ

[levancho]

Hi,

I see that in my Mac version of smart fox there is no sfs2x-standalone.vmoptions

so where should I put my debug info for JVM?

You should use the sfs2x.sh script to launch the server and modify it.
In any case you can alter the JVM parameters directly from the AdminTool, did you know that? Just launch the tool and choose ServerSettings, then click on the JVM Settings tab.

Cheers

Hi Lapo,
we are using sfs2x 2.1.0v running on Redhat linux. and trying to connect from windows 64bit eclipse editor.

we modified the sfs2x.sh file and added the jvm debug into it

Code: Select all

"JAVA_OPTS="$JAVA_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,address=9933,server=y,suspend=n"
"

now when i connect through eclipse editor it is giving below error -
eclipse -
failed to connect to remote VM
and in the mmo log we see below error

Code: Select all

 WARN  [SocketReader] binary.BinaryIoHandler     - Incoming request size too large: 1146572845, Current limit: 8000000, From: { Id: 1, Type: DEFAULT, Logged: No, IP: 192.168.0.179:30148 }

what settings need to be done in order to debug sfs2x server.

just for ref. after adding debug option our sfs2x.sh file looks as below -

Code: Select all

# Use -Dlog4j.debug for Log4J startup debugging info
# Use -Xms512M -Xmx512M to start with 512MB of heap memory. Set size according to your needs.
# Use -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled for PermGen GC

#-Xdebug -Xrunjdwp:transport=dt_socket,address=9933,server=y  suspend=y -jar stockTradingGUI.jar

JAVA_OPTS="$JAVA_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,address=9933,server=y,suspend=n"

JRE_FOLDER="../jre/bin"
JAVA_CMD="java"
if [ -d "$JRE_FOLDER" ]; then
    JAVA_CMD="../jre/bin/java"
fi

CPATH="./:lib/*:lib/Jetty/*:extensions/__lib__/*"
${JAVA_CMD} -cp ${CPATH} -Dfile.encoding=UTF-8 com.smartfoxserver.v2.Main $1 $2

Thank you

Well, the problem is that you are trying to use as the debug port the SFS2X default port (TCP 9933). This way Eclipse will not "speak" to the debugger, instead it will talk to SFS2X which won't understand that protocol. And additionally it is refusing the data because it's a too large packet.

Please change the debugging port.

Thanks
