此规范是《SCA装配模型规范》[1]的扩展，定义了Java类如何提供SCA构件的实现，以及做为一种组件实现类型的该类在SCA中是如何被使用的。

此规范需要用到《SCA Java通用注解注解和API规范》[2]中定义的所有注解和API。在《SCA Java通用注解和API规范》中，所有被引用的的注解和API都是定义良好的，除非另行说明。此外在这些Java通用注解和API规范中定义的语义都是标准化的。-The specification was " SCA assembly model specification"　[1] the expansion of the definition of the Java type of how to provide SCA components to achieve, and as a component in the realization of such types of SCA is how it has been used. This specification requires a " SCA Java General Notes Notes and API specification"　[2] in the definition of all the Notes and API. In " SCA Java Common API Notes and norms" , all have been cited in the explanatory notes and API are well-defined, unless otherwise indicated. In addition, these Java General Notes and API specification is the definition of semantic standardization.
