When one or more applications have been written, we may want to create a complete system composed of these applications and a subset of Erlang/OTP applications.
To achieve this goal, we create a release resource file that defines the applications to be included in the release.
The published resource file is used to generateStart scriptAndRelease package. The system sent and inst

If the user needs to provide his/her work permit or key to access the security guard after the password is entered, this is to use all the user's creden for verification. Further, according to regulations, the user must also be a person recognized by the guard before the user can access the website. This is the identity authentication method of the user's biological characteristics. Therefore, all the

Here is a few resources:Programming Erlang, by Joe Armstrong. A Good book, really teaching-the fundamentals of Erlang and hot the abstractions is built. Some people found it a bit dry and hard to follow. Joe Armstrong is the original creator of Erlang, along with Robert virding and Mike WilliamsErlang in practice, screencasts by Kevin Smith. He starts from scratch and makes you build a distributed chats application with Mochiweb. Then you refactor it to use the
impressive tracing feature, as well as tools based on this feature such as Recon Trace. Erlang's self-introspection greatly improves development and also improves maintenance on complex systems.
Static connection
Yes, one thing is good but it becomes bad, like spending a lot of time running on a system. Although no connection can cause slow execution, it gives Erlang an advantage in code substitution on a running system. It is important that because of the scheduling and garbage collection stra

Javamail is Sun's application interface for email processing. It provides some of the most common implementation methods for mail transfer protocols and provides easy methods to call them. Javamail is an application interface released by Sun, so it is not included by JDK yet. Therefore, you need to download the javamail package from Sun's official website. In addition, sun's JAF (JavaBeans activation framework) is also required. Otherwise, javamail cannot run.
The core javamail API consists of s

This interface defines the factory used for implementing the datagram socket.

callAccountManager.getAuthToken()To get the token.
Watch out! Calling methods onAccountManagerCan be tricky! Since account operations may involve network communication, most ofAccountManagerMethods are asynchronous. This means that instead of doing all of your auth work in one function, you need to implement it as a series of callbacks. For example:
AccountManager am = AccountManager.get(this);Bundle options = new Bundle();am.getAuthToken( myAccount_, // Account retrieved
