With this method, existing applications that use the Authenticator class do not need to be modified, so long as users are made aware that this notation must be used. Basic authentication is case sensitive for both the user name and password, so type the user name and password exactly as defined for the GlassFish Server. The username and password are encoded in base 64 and are therefore easily obtainable by anyone who has access to the packet data. The class MyAuthenticator will be completely ignored, and the output will be simply Hello, You got me! Any of the following methods may be called by the implementation of getPasswordAuthentication in order to decide how to handle each request for credentials. Copy-pasting code here in the comments is a bit sub-optimal.

In the example application included with this tutorial, many of these steps have been completed for you and are listed here simply to show what needs to be done should you wish to create a similar application. Hello Eugen, I have finally gotten a simplified version done. This means that every time we access a resource, the nonce will be different, and thus the digest will be different, even if we access the resource in the same second. See below for how to distinguish between proxy and server authentication. Related to Mat's comment : Here is an example used by my team and I : import org. However, other two request with the authentication string in the header has got the successful output. It Base64 encodes the resulting string.

We can not change the value of a String object once it is initiated. You can think of a public key certificate as the digital equivalent of a passport. This is a common issue when dealing with time-limited authentications! If a proxy is being used, then it cannot be used for server authentication.

Each request is only valid once, and only once. This encoding approach is not secure as the encryption approaches like. Controlling which authentication scheme is used When a server needs a client to authenticate, it may propose a number of schemes to the client for example digest and ntlm and the client may choose from among them. In fact, if you are running on a Windows machine as a domain user, or, you are running on a Linux or Solaris machine that has already issued the kinit command and got the credential cache. The server can generate the digest as well, since it has all information. This behavior is normally disabled, because not all servers support it. If the user needs to ensure that a particular scheme is used, then the following system property can be set to modify the default behavior.

The only authentication information needed to be checked in your Authenticator is the scheme which can be retrieved with getRequestingScheme. Maybe it can help someone else.

StringBuffer updates the existing objects value, rather creating new object. If these credentials are not accepted by the server then the user's authenticator will be called. Depending on that and based on what the server responds with — you should be able to figure out the problem. I did see an entry that seemed to have similar symptoms to mine suggest: new AuthScope AuthScope. Fallback If the server has provided more than one authentication schemes including Negotiate , according to the processing order mentioned in the last section, Java will try to challenge the Negotiate scheme. Just an aside, I also putting the logging.
