Executing jar file

Rails
1

Hello

With my controller i am executing a JAR file like this:

begin
pipe = IO.popen(“java -jar D:/Projets/TstSimple/lib/tstlib.jar”)
rescue Exception => e
msg = e.message
end

I would like to not have to specified the path of the jar file:
pipe = IO.popen(“java -jar tstlib.jar”)

Is there a directory where I can put my JAR file so rails be able to
execute the java command like this?

Thanks

regards

You can reference it with #{RAILS_ROOT}

So something along the lines of

pipe = IO.popen(“java -jar #{RAILS_ROOT}/jars/tstlib.jar”)

and then make a jars folder in the root of your app and place your jar
there.

This should work… might require tweaking, look into using
#{RAILS_ROOT} (as I’m still a bit of a newbie here… and to Rails).
