ENC28J60 Ethernet Module WEBSERVER ERROR

ENC28J60 Ethernet Module and MEGA2560 I did with webduino webserver does not open.

But you use the following code opens.

// A simple web server that always just says "Hello World"

#include "etherShield.h"
#include "ETHER_28J60.h"

int outputPin = 6;

                                                                // so unless you have more than one of these boards
                                                                // connected, you should be fine with this value.
                                                           
static uint8_t ip[4] = {192, 168, 1, 15};                       // the IP address for your board. Check your home hub
                                                                // to find an IP address not in use and pick that
                                                                // this or 10.0.0.15 are likely formats for an address
                                                                // that will work.

static uint16_t port = 80;                                      // Use port 80 - the standard for HTTP

ETHER_28J60 e;

void setup()
{ 
  e.setup(mac, ip, port);
  pinMode(outputPin, OUTPUT);
}

void loop()
{
  char* params;
  if (params = e.serviceRequest())
  {
    e.print("<H1>Web Remote</H1>");
    if (strcmp(params, "?cmd=on") == 0)
    {
      digitalWrite(outputPin, HIGH);
      e.print("<A HREF='?cmd=off'>Turn off</A>");
    }
    else if (strcmp(params, "?cmd=off") == 0) // Modified -- 2011 12 15 # Ben Schueler

to reduce costs ENC28J60 Ethernet Module need to use how can I solve this problem ?
