Re: Third Party software invocation through a Java Application

Question

hi,
use the java.lang.Runtime.exec() to execute the command and pass as an arguement the necessary file that you wish to invoke.
eg
     // for eg if filename extension is .pdf
String pdf = "C:\\Program Files\\Adobe\\Acrobat 4.0\\Reader\\AcroRd32.exe";
     String [] cmd = {"start", pdf,"c:\\sample\\sample.pdf"} ;
     Process process = Runtime.getRuntime().exec(cmd) ;now put that code in a if condition dependent on the type of file extension..
hope that helpzz

Answer 1

I wrote a sample program :
public class Trial {
     public static void main(String[] args) {
          try {
               String pdf = "C:\\Program Files\\Adobe\\Acrobat 5.0\\Reader\\AcroRd32.exe";
               String [] cmd = {"start", pdf,"c:\\test\\intro.pdf"} ;
               Process process = Runtime.getRuntime().exec(cmd) ;     
          } catch (Exception ex) {
               System.out.println("Exception caught " + ex);
               ex.printStackTrace();
          }// end catch()
     }// end main()
}// end class
I am working on Windows 2000 and JDK1.3.1
The error i got is
Exception caught java.io.IOException: CreateProcess: start "C:\Program Files\Ado
be\Acrobat 5.0\Reader\AcroRd32.exe" c:\test\intro.pdf error=2
