[Webware-discuss] How execute an app outside of the appserver

From: Marcelo Ametller <mametller@gm...> - 2006-01-24 18:16

hi

as I generate a process in the server, who does not occupy memory of
appserver from a navigator?

I have a servlet with form and a button label “import”
the action for the 'button' is a function that takes a file .txt and
enters it, into a postgresql/table.

I need that this function goes off from the button, at the browser, but
as it consumes many resources (memory,threads), that the fall of
appserver does not cause.

Span a completely separate process. You can store the pid of the process 
in your session so servlets can check whether the process is still 
running. The process could also signal "done" by creating a certain file 
or writing something to the database.

Process management is described in section 6.1.5 of the Python standard 
lib docs.
