debug war that in tomcat

1st stp:
update the tomcat's catalina.bat file:
added on line under
:gotTmpdir
set JAVA_OPTS=%JAVA_OPTS% -agentlib:jdwp=transport=dt_socket,server=y,address=8000 -Xms256m -Xmx1024m

at here, we added listen for 8000, and also add memory for tomcat jvm.


2nd stp:
confin the eclipse
1, open "Debug Configurations" dialog window.
2, found the "Remote java Application" and right click ->  click "new" action
3, select connect tab and config the project which deploy to war.

for now every things is okay, we start tomcat.
tomcat should be listen foe 8000 and waiting for that.
start the debug that 2nd stp.
