Hi,
I need to access a secure webpage using Java.
Normally, to login, I need to enter userID, password and the server that I want to connect to..
The page is made up of PHP.
I tried using Authenticator, but didn't work.
Can anyone tell me how to proceed with this?

HI,
Ok, your server is using the post method. Therefore it is interesting for u to have a look at the PrintStream class.
http://java.sun.com/javase/6/docs/api/java/io/PrintStream.html
I suppose you have allready an establised Socked to the Server. In that case it is easy for u to get an Outputstram to set up the PrintStream. As soon as this is done u can submit your datas through the println method form the PrintStream class.
Lemme give you the code:
( I've made up the server name and IP address here. But, used the real data in my code. )
try
{
Socket s=new Socket("200.200.200.200",80);
BufferedReader in=new BufferedReader(new InputStreamReader(s.getInputStream()));
PrintWriter out=new PrintWriter(s.getOutputStream(),true);
str="HEAD /src/redirect.php?login_username="+name+"&secretkey="+password+"&loginServer=MyServer HTTP/1.0\n";
out.println(str);
str="a";
int count=0;
String test;
String cookie[]=new String[3];
for(int i=0;i<13;i++)
{
str=in.readLine(); // == null if error in connection
if(str.length()>8)
{
test=str.substring(0,10);
if(test.equals("Set-Cookie"))//We need cookies: can't proceed unless we have them
{
cookie[count]=str.substring(11)+";";
count++;
}
}
}
String cookies="Cookie:"+cookie[0]+cookie[1]+cookie[2];
in.close();
out.close();
s.close();
str="a";
s=new Socket("202.141.80.21",80);
in=new BufferedReader(new InputStreamReader(s.getInputStream()));
out=new PrintWriter(s.getOutputStream(),true);
str="GET /src/right_main.php HTTP/1.0\n"+cookies+"\n";
out.println(str);
while((str=in.readLine())!=null)
{
System.out.println(str); // write to mail.txt
}
in.close();
out.close();
s.close();
}
catch(IOException e)
{
System.out.println(e);
}
catch(StringIndexOutOfBoundsException z)
{
System.out.println(z);
}
