windows - Find and kill a specific Java process from another Java App -


i have several java processes running on windows machine. have java process supposed monitor other processes , periodically kill or restart new ones.

if have java process running com.foo.main1 , 1 running com.foo.main2 - how can monitoring process find , kill main2 process?

update: have code can execute command line tasklist.exe , parse it, no matter do, see java.exe process, not class executing

update 2: not have ability install non-java programs.

it's going lot simpler using os-specific tools , using runtime.exec() run them, i'll try , give platform independent answer:

it might possible platform independently using attach api. comes jdk, use include tools.jar jdk on program's classpath.

to list of virtual machines on system, use virtualmachine.list(). can get/parse arguments virtual machine descriptor objects returned this.

the attach api allows load agents already-running java processes. since want kill java process, can write java agent runs system.exit() (or if really want dead use runtime.halt() instead) when agent loads.

once identify 1 want kill, attach , load killer agent (the agent has built jar file, accessible java process needs loaded into). shortly after agent attached process should die.

these links might also:

an oracle blog on attach api

package documentation java.lang.instrument (has detailed instructions on how build agent jar)

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
