With this chapter, we begin part 6 of the book, showing some internal mechanisms of Wildly to manage the classes. Each application server is pushed by the enterprise specification to implement its own deployment mechanism. Deployment is the basic operation to install enterprise applications. Apart from the SPI interfaces provided by the enterprise specifications, the application servers are free to manage, in an independent mode, the memory and the clustering, providing proper mechanisms and frameworks. The application servers provide their tool to make this operation very simple. In this chapter, we'll get on with the following topics:

• The available package we can deploy
• Tools provided by the internal implementations of WildFly
