is JNI overkill

[SirThanxALot]

Hello,

I want to call Winamp (more generally, an executable) from within a java
app. Is it really neccessary to use the whole JNI thing-a-ma-jig or is
there an also easy hack?

And is it possible to pass command line options like one would use in a
command prompt such as
'snip' winamp somefile.mp3 'snip'

any suggestions?
many thanx

Hi,

If you are not too bothered about interacting with the exe from the java app
(IE, just launching it, and waiting for it to finish, etc) then have a look
at:

Process proc = Runtime.exec("winamp", new String[] {"somefile.mp3"});

Have a look at the JAVA API docos for this and you will see you are able to
get the in/out/err stream, and wait for the process to finish etc..

Process proc = Runtime.getRuntime().exec("program" + " " + args) did the
trick in Runtime,getRuntime().exec(String, String[]) the array is meant
to give environmental settings such as path etc, not for arguments
