Hi,
# create a diretory named 'jars' (any name) inside public directory
and move your jar file inside this directory.
def exjar
args1= ""
args2 = ""
Dir.chdir("#{RAILS_ROOT}/public/jars/") do
# i'm using linux environment. If windows environment, change
the path to the java according to the java directory installed in your
machine.
retResult = system("/home/user1/java/jdk1.6.0_07/bin/java -jar
Sample.jar #{args1} #{args2}")
end #chdir
end
If you get error while running this, please post the error here.
Thanks
Senling
