JavaServer Pages (JSP) is an open, industry-standard designed to quickly and easily create web pages that contain dynamic content. JSP uses special tags embedded in an HTML or XML file. Once submitted, the server interprets these tags and any included scriptlets, and generates the content.

Using JSP, the browser can access a JDBC database or a file through the server. The server then sends the results back in the form of an HTML or XML page to the browser.

IBM's WebSphere utilizes JSP -- among other technologies -- to quickly transform static web sites into vital sources of dynamic Web content with business logic.
