Re: WOInject failure with WOMonitor

Ok new stuff I was not aware of !
I've just built the app on my personal mac book air, with no real WO
installed (we build wo apps with gradle), and no WOBootstrap.jar is added
to the woa. I said to myself it will not work without it, but to my
surprise it launches the app with -classpath="all the classpath from the
txt classpath files"... and of course the app launches...
But I fear the command line length limitation on certain unix....

So, especially the maven guys, do you include the WOBootstrap.jar ? And if
so, which one is it ?!

Thanks for your answers

Alex
