How to call a perl module from Java program.

Question

Hi,
I create a simple java program as follows
class test{
public static void main(String args[])
{try {                    
Runtime r = Runtime.getRuntime();
r.exec("perl test.pl");
catch(Exception e)
{e.printStackTrace();}
and test.pl is located in the same directory as the java program. The program compiles but with no return as I execute it. I am not sure what is wrong.
Thanks,

I think the wrong line is here; r.exec("perl test.pl");
Usually the JVM needs the full path.If the path for either the executable or the script was wrong then, given the code posted, it would not hang.

To automatticaly get the path (if the file is in the
class path) use
System.getProperty("java.class.path")
That gets paths(plural).
Try this:
r.exec("perl " +
System.getProperty("java.class.path") + "\test.pl");I am rather certain that that won't work on any standard operating system.
