Run JBoss, Tomcat/Tomee in debug mode

 

The needed params are:

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

For jboss as 7 in bin/standalone.bat (or sh) add those additional params to line 53

set JAVA_OPTS=-Dprogram.name=%PROGNAME% %JAVA_OPTS%

the line will look like this:

set JAVA_OPTS=-Dprogram.name=%PROGNAME% %JAVA_OPTS% -Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n

For tomcat/tomee

in catalina.bat (.sh) at this as the first line in file:

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