Basic Authentication with Resteasy client

Question

I\'m trying to perform an basic auth to the login-module which runs on my jboss using REST. I already found an StackOverflow topic which explains how to authenticate with creden

You can add a raw authorization header to your REST client by invoking .header(HttpHeaders.AUTHORIZATION, authHeader) in your client configuration. The credentials must be packed in authorization header in the format of "user:pass", encoded as base64 byte array and then appended to the string "Basic " which identifies basic auth.

This is the whole snippet (inspired by this post on baeldung)

    String auth = userName + ":" + password;
    byte[] encodedAuth = Base64.encodeBase64(auth.getBytes(Charset.forName("ISO-8859-1")));
    String authHeader = "Basic " + new String(encodedAuth);

    authToken = restClient.target(restApiUrl + loginPath)
            .request()
            .accept(MediaType.TEXT_PLAIN)
            .header(HttpHeaders.AUTHORIZATION, authHeader)
            .get(String.class);

This worked for me in a Resteasy client. For information, when testing this with wget I had to use the --auth-no-challenge flag.
