I did it.
I made this entry in catalina-policy:
// Mein Eintrag zum ausführen eines Prozesses:
grant codeBase "file:${catalina.home}/webapps/my_exec/-" {
permission java.io.FilePermission "/home/chris/c/file-test","execute";
};
Then I wrote this servlet:
[code]
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class FireStarter extends HttpServlet
{
public void doGet ( HttpServletRequest req, HttpServletResponse res ) throws
ServletException, IOException
{
int rueckgabe = 0;
rueckgabe = Fireone();
res.setContentType ( "text/html" );
PrintWriter out = res.getWriter();
out.println ( "<HTML>" );
out.println ( "<HEAD><TITLE>Firestarter</TITLE></HEAD>" );
out.println ( "<BODY>" );
out.println ( "<BIG> Firestarter </BIG>" );
out.println ( "</BODY></HTML>" );
}
public int Fireone ( )
{
int rueck_gabe = 0;
try
{
String cmd1 = "/home/chris/c/file-test";
Runtime rt = Runtime.getRuntime();
Process myproc = rt.exec( cmd1 );
rueck_gabe = myproc.waitFor();
System.out.println("die Rueckgabe war: " + rueck_gabe );
}
catch( IOException ioexc )
{
ioexc.printStackTrace();
}
catch( InterruptedException intexc )
{
intexc.printStackTrace();
}
return ( rueck_gabe );
}
}
[/code]
And I put into a package ( with WEB-INF/ the web.xml-files and so on...)
my_exec.WAR.
BUT this is the result/trace I got :-(
