--- first servlet ---
public class transaccion1 extends HttpServlet
{
void increferencia(HttpServletRequest req,HttpServletResponse res)
{
try {
InputStream is = new FileInputStream("referencia");
DataInputStream di = new DataInputStream(is);
referencia=di.readInt();
is.close();
OutputStream os = new FileOutputStream("referencia");
DataOutputStream oo = new DataOutputStream(os);
if (referencia==9999) referencia=0;
else referencia = referencia + 1;
oo.writeInt(referencia);
os.close();
} catch (Exception e) { }
}
}
--- second servlet ---
public class transaccion1 extends HttpServlet
{
void increferencia(HttpServletRequest req,HttpServletResponse res)
{
try {
InputStream is = new FileInputStream("referencia");
DataInputStream di = new DataInputStream(is);
referencia=di.readInt();
is.close();
OutputStream os = new FileOutputStream("referencia");
DataOutputStream oo = new DataOutputStream(os);
if (referencia==9999) referencia=0;
else referencia = referencia + 1;
oo.writeInt(referencia);
os.close();
} catch (Exception e) { }
