Question

I’m trying to create a J2ME app, which talks to webserver using HttpConnection connector.

When I am talking to the WebServer, I have to authenticate using Basic HTTP auth, which normally goes like

http://username:[e-mail]/rest/api/method

But in J2ME, when I construct a url of this form, it doesn’t work.

I also tried adding request property,

hc = (HttpConnection) Connector.open(url);
hc.setRequestProperty("User", "alagu");
hc.setRequestProperty("pass", "mypassword");


but didn’t work.

Has anyone done j2me based HTTP auth before? Thanks in advance.

It could be J2ME has no support for basic authentication, I might be wrong. If you want to try just setting the authentication header in the request yourself you’ll likely need a different header then what you’re using.

From the rfc:

To receive authorization, the client sends the userid and password,
separated by a single colon (“:”) character, within a base64 [7]
encoded string in the credentials.

[…]

If the user agent wishes to send the userid “Aladdin” and password
“open sesame”, it would use the following header field:

 Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==

So just create the string “User:Password”, base64 encode it and then call setRequestProperty("Authorization", "Basic "+ encodedUserAndPass)
