JavaServer Faces
JavaServer Pages（JSP）是由 Sun Microsystems 于 1999 年发布的一种服务器端技术规范，用于创建基于 HTML、XML、SOAP 等文档类型的动态网页。它允许开发者将 Java 代码直接嵌入 HTML 页面，相比 Servlet 更便于编写动态内容，并支持自定义标签、表达式语言等特性。JSP 页面在首次访问时由 JSP 编译器解析并转换为可执行的 Java Servlet，也可预编译以提升性能。该技术平台无关，属于 Java 2 Enterprise Edition（J2EE）的一部分，后由 Eclipse 基金会接管并更名为 Jakarta Server Pages（Jakarta Pages）。
