How can I pass the userId and pasword to proxy while opening the URLConnect

Question

First I was having problem on how can I send a userid and password for proxy authentication while trying to connect to a servlet from a applet, finally I figured out that I need to add Authenticator as
Authenticator.setDefault(new MyAuthenticator());
and everything started working fine but only from a java application not from a applet. In applet when I try to add a Authenticator I get exception that cannot add defualt Authenticator. Please someone help how can I add Authenticator in a applet? I dont think for adding a defualt autheticator I need to get my applet signed. Please comment.
Thanks,

Answer 1

Can u tell me please how can I add
java.net.NetPermission on the target setDefaultAuthenticator.
And by the way for sending the password I tried the following code which doesn't use Authenticator and it worked. U can use it what Iam doin is iam using my own base64encoder instead of jdk's which was giving problems to me. U can try with jdk base64encoder and if u get any problems let me know I'll send u my version of the encoder.
If u r using any images in ur applet and getting the images by using getImage() method then probably while getting the image applet is prompting for user and password.
URLConnection con = url.openConnection();
String authString = "userid:passsword";
String auth = "Basic " + new sun.misc.BASE64Encoder().encode(authString.getBytes());
//String auth = "Basic " + new MyBase64Converter().encode(authString.getBytes());
con.setRequestProperty("Proxy-Authorization", auth);
