Need help -- Pass two params in java in command line through perl

Question

I need to pass two params in a java file similar as I pass from command line.

Something like

$ENV{classpath} = ".\\my.jar;$ENV{classpath}";
system("$ENV{JAVA_HOME}\\bin\\java com.myclass  param1  param2"  );

how can i achieve this in a perl script?

seems you are looking for a perl script, not a java solution. — Helios, Jan 20 '14 at 09:36
Thanks Bosko, BUT it is all about calling perl in java. I need to call java in perl with runtime args.. I did not get any proper info on search, — smriti, Jan 20 '14 at 10:02
@bosko-mijin, I suppose OP wants to call Java from Perl, not the opposite way round... — MarcoS, Jan 20 '14 at 10:02
@smriti: It looks to me like your original code should work. What problems are you having? — Dave Cross, Jan 20 '14 at 13:49

I don't have access to my work system still let me give it a try. It should work for you.

my $cpJava=" -cp /your/classpath";
my $myClass="your class name";
my $runMe="Java path ".$cpJava." ".$myClass." ".join(' ', @ARGV);

@ARGV will have all your parameters. Learn more about join from here.

Then use system:

system($runMe);

Hope it would work for you.

Wow Nik. Thank you soo much. So if i want to pass two params i can @ARGV = ("param1", "param2"); and pass.. thanks – smriti Jan 20 '14 at 10:12
But what @Nik has given you is, effectively, no different from what you had originally. He's just building up the string before passing it to `system`. – Dave Cross Jan 20 '14 at 13:46
`my $runMe = "Java path $cpJava $myClass @ARGV";` - this does the same thing too. Perl interpolates variables in a double-quoted string. – Dave Cross Jan 20 '14 at 13:48
