RunTime exec configuration for the child

[puzzlecracker]

if I want to run a java application from the same java application:
meaning parent process spawns a child process, but passes different
parameters (to avoid infinite spawning); does the child inherits
parent's classpath and other configurations
or do I need to pass the classpath along?

If I am using linux env. and exported the classpath, will it be used.

Basically, I want the application to run on win32 (eclipse) and Linux.

Also, child process does a lot of printing, should create another
thread to monitor and read its output or what?

what is the general pattern for this kind of a thing.

Suggestions and examples will be appreciated.

Thanks

ps.I was trying to do something with listerner but cannot get printing
to work.....

If you've specified the classpath via the "-classpath" command line
option, then you'll need to repeat that on the child process. If you've
specified it with the CLASSPATH environment variable, that will be
inherited by the child process by default.

It's important to note that there's no special case in Process for
invoking another JVM. You have to do it just like you would any other
process, and it follows the same rules.

Also, child process does a lot of printing, should create another
thread to monitor and read its output or what?

By printing, I assume you mean writing to the console (as opposed to
using a printer, for example). Yes, you will need to read from the
resulting streams eventually, so the child process doesn't block
indefinitely.
