Can JSP run sys command lines?

["zeallousbigpond.net.au" <ze...@bigpond.net.au>]

Can JSP call system exec commands in linux?.....

Runtime.getRuntime().exec("pdflatex")

does this work in JSP? ......fyi, pdflatex is installed in another server..

so..when you run exec in tomcat...does it run and view those commands/programs that exist ONLY in the tomcat directory?

Re: Can JSP run sys command lines?

[Tim Funk <fu...@joedog.org>]

The restrictions are the same as launching any process from java. Such as
- Relative vs absolute command line
- If relative - is the current working dir correct
- Is the user_id of the running process correct
- Environment variables carried to the child process
- If there is a secutiry manager - will it allow exec
- ...
