Running a perl shell command through a java program on linux platform

Question

i'm trying to execute the following command in a java program "perl xxx.pl" using the runtime.getruntime method
here is the piece of code
String[] cmd={"perl","-c","AraMorph.pl",""};
Process p = Runtime.getRuntime().exec(cmd,null,new File("/home/ahmed/buckwalter_morphan_1/data"));
p.waitFor();
BufferedReader in=new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line=in.readLine())!=null)
System.out.println(line);
but it doesn't output anything even if i tried to print the output to a file
i'm trying to execute this program on linux platform but its working properly on a windows platform
thx

Answer 1

String[] cmd={"perl","AraMorph.pl"," </home/ahmed/in.txt"," >/home/ahmed/ast.txt"};
Process p = Runtime.getRuntime().exec(cmd,null,new File("/home/ahmed/buckwalter_morphan_1/data"));
BufferedReader in=new BufferedReader(new InputStreamReader(p.getErrorStream()));
String line;
while ((line=in.readLine())!=null)
System.out.println(line);
p.waitFor();
String str2=p.getInputStream().toString();
System.out.println("==================================="+str2);
and it still outputs nothing but goes in something like infinite loop or as assumed in the article u suggested a deadlock but even all solutions to all pitfalls didn't succeed
