this is my Python script<br>
<br>
prova.py<br>
-------------------------------------<br>
import sys<br>
import getopt<br>
<br>
def main():<br>
&nbsp;&nbsp;&nbsp; print "CIAO...."<br>
&nbsp;&nbsp;&nbsp; # parse command line options<br>
&nbsp;&nbsp;&nbsp; try:<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; opts, args = getopt.getopt(sys.argv[1:], "h", ["help"])<br>
&nbsp;&nbsp;&nbsp; except getopt.error, msg:<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print msg<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print "for help use --help"<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; sys.exit(2)<br>
&nbsp;&nbsp;&nbsp; # process options<br>
&nbsp;&nbsp;&nbsp; for o, a in opts:<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if o in ("-h", "--help"):<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print "AIUTO"<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; sys.exit(0)<br>
&nbsp;&nbsp;&nbsp; # process arguments<br>
&nbsp;&nbsp;&nbsp; for arg in args:<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print "NON definito" # process() is defined elsewhere<br>
<br>
if __name__ == "__main__":<br>
&nbsp;&nbsp;&nbsp; main()<br>
-----------------------------------------------------<br>
<br>
And this is my java code<br>
<br>
Prova.java<br>
-----------------------------------------------------<br>
import org.python.util.PythonInterpreter;<br>
import java.io.*;<br>
<br>
public class Prova {<br>
<br>
&nbsp;&nbsp;&nbsp; /**<br>
&nbsp;&nbsp;&nbsp; &nbsp;* @param args<br>
&nbsp;&nbsp;&nbsp; &nbsp;*/<br>
&nbsp;&nbsp;&nbsp; public static void main(String[] args) {<br>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; // TODO Auto-generated method stub<br>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; PythonInterpreter interprete = new PythonInterpreter();<br>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; Writer out = new StringWriter();<br>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; Writer err = new StringWriter();<br>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; interprete.setErr(err);<br>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; interprete.setOut(out);<br>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; System.out.println("Avvio");<br>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; interprete.execfile("prova.py");<br>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; System.out.println(out);<br>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; System.out.println(err);<br>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; System.out.println("Fine");<br>
&nbsp;&nbsp;&nbsp; }<br>
<br>
}<br>
-----------------------------------------------------------<br>
<br>
