exec an application and write output to a file

[jzhao <jz...@vbi.vt.edu>]

Hi there,

I was trying to run a .exe in my web service with Java runtime. The code looks like:

command = "teiresias_char -l"+ L + " -w"+ W
       +" -i"+ inputFile
       +" -o"+ resultFile
     + " -c"+ C +" -k"+ K +" -s";


  Runtime rt = Runtime.getRuntime();
  try {
   Process p=  rt.exec(command);
   re = new BufferedInputStream (p.getInputStream());
   re.close();
   System.out.println("excecution suceed.");


   }
   catch (IOException ex)
   {
    System.out.println("command is not executable!");
       }

so when the command has been executed, i should get the result written to a file named "resultFile". The server implementation runs well on my local machine ( I got the result file). However, after I deployed it to the Tomcat/Axis (beta2) and tested with a small local client,  I got the "excecution succeed" message, but I didn't see any result file generated. and later when i tried to read from that file, I got "FileNotFoundException".

Any clue what's going on here?

Thanks a lot!

quick suggestion -- scan all drives and al ldirectories
for the output.  If on linux try running updatedb from
root and then 'locate blat' to find the file.

Just a thought ...
