JSP problem:request object returning null
Hello,
I am using an authorization JSP before proceeding to another JSP. When the authorization is valid, I go to the next JSP. Now there is a drop down box in this next JSP. I select a value from this drop down and submit the form. When I retrieve the value of this drop down in the next JSP using request.getParameter(), it returns null. The problem is, when I don't use the authorization JSP and proceed directly to the next JSP, and select a value from the drop down, and go to the next JSP, the request.getParameter() returns the valid value.
In the authorization JSP, I am using the following code, may be there's the bug.
String auth = request.getHeader("Authorization");
if (auth == null) {
response.setStatus(response.SC_UNAUTHORIZED);
response.setHeader("WWW-Authenticate", "NTLM");
return;
}
if (auth.startsWith("NTLM ")) {
byte[] msg =
new sun.misc.BASE64Decoder().decodeBuffer(auth.substring(5));
int off = 0, length, offset;
if (msg[8] == 1) {
off = 18;
byte z = 0;
byte[] msg1 =
{(byte)'N', (byte)'T', (byte)'L', (byte)'M', (byte)'S',
(byte)'S', (byte)'P', z,
(byte)2, z, z, z, z, z, z, z,
(byte)40, z, z, z, (byte)1, (byte)130, z, z,
z, (byte)2, (byte)2, (byte)2, z, z, z, z, //
z, z, z, z, z, z, z, z};
//
response.setStatus(response.SC_UNAUTHORIZED);
response.setHeader("WWW-Authenticate", "NTLM "
+ new sun.misc.BASE64Encoder().encodeBuffer(msg1).trim());
return;
}
else if (msg[8] == 3) {
off = 30;
length = msg[off+17]*256 + msg[off+16];
offset = msg[off+19]*256 + msg[off+18];
s = new String(msg, offset, length);
//out.println(s + " ");
}
else
return;
length = msg[off+1]*256 + msg[off];
offset = msg[off+3]*256 + msg[off+2];
s = new String(msg, offset, length);
//out.println(s + " ");
length = msg[off+9]*256 + msg[off+8];
offset = msg[off+11]*256 + msg[off+10];
s = new String(msg, offset, length);
s1=s.toString().trim();
// Our Logic starts here now that we have the login user name
char[] temp = s1.toCharArray();
char[] user_char= temp;
String userName = "";
int j=0;
for(int i=0;i<s1.length();i++){
if((int)temp!=0){
user_char[j]=temp;
j++;
}
}
Please help.>
