Hello out there,
I try to create a Tomcat-servlet, which enables me to call a process on my
host. This is my attempt:
[code]
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Testservlet1 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>Testservlet1</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/eigener-proc";
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 this is the result:
[quote]

I know I have to edit the catalina.policy but in which part is not clear to
me.
Can anybody help me out?
I have unfortunately not the time to work this out. Otherwise we choose
Apache/Perl for this purpose.
