The Solar Framework for PHP 5 (2010 Confoo)Paul Jones
This presentation is a whirlwind tour of the Solar framework for PHP 5. After a short bit of background, the presentation will outline the major concepts in Solar: everything is a library, the unified constructor, unified configuration, inherited configuration and localization, unified factory and adapter systems, lazy-loading registry, and the dependency-injection system. Next is an overview of how the dynamic dispatch cycle works in Solar, and how it compares to other framework dispatch cycles. From there we will move on to the SQL system, including the MysqlReplicated adapter, and lead into the ORM system. The ORM overview will briefly cover models, collections, records, automated filters, automated form generation, and more. After discussing the authentication layer, CLI tooling, and command-line controllers, it will wrap up with a brief discussion of Solar project architecture, and a short note on Solar's performance in relation to other popular frameworks.
Organinzing Your PHP Projects (2010 Memphis PHP)Paul Jones
By using a single organizational principle, developers can easily make their project structure more predictable, extensible, and modular.

Sling is a RESTful web application framework that uses JCR repositories like Apache Jackrabbit as its data store. Sling maps HTTP requests to content resources in the repository and uses the resource type to locate the appropriate rendering script. The request URL is decomposed into the resource path, selectors, extension, and suffix path. Sling searches for a node matching the resource path and then locates a script based on the resource type and any selectors. Sling scripts cannot be called directly and must be resolved through the resource to follow REST principles. This document discusses how Sling maps URLs to content resources and scripts to process requests.

Java Server Pages (JSP) is a technology that allows developers to create dynamic web applications using Java code embedded in HTML pages. JSP pages are compiled into Java servlets, allowing dynamic content to be generated. JSP supports the use of scripting elements like expressions, scriptlets, and declarations directly in HTML pages to add dynamic functionality. Common elements like directives, actions, and standard tags provide functionality like including pages, passing parameters, and abstracting common patterns.
This document provides an introduction to Java Server Pages (JSP) technology. It explains that JSPs allow embedding Java code and dynamic content in HTML pages to create dynamic web applications. JSP pages are translated into servlets by the JSP engine. The document outlines the basic structure of JSP files and describes the different tag types including scriptlets, expressions, declarations, and directives that allow adding dynamic functionality to JSPs. It also introduces common implicit objects like request, response, out, and session that are available in JSP pages.

JSP is a technology based on Java that produces dynamic web pages. JSP files contain HTML tags as well as special JSP tags where Java code is embedded. There are three main types of JSP elements - directives, scripting elements, and action elements. Directives provide information to the JSP engine, scripting elements contain Java code, and action elements perform tasks like accessing Java beans. Common implicit objects in JSP include application, page, session, and request objects. Java beans can be used with JSP through action tags like useBean, setProperty, and getProperty.

5. Basic Idea
• Approach
– indicator attribute designates section (usually div or span)
that will be enabled while results are being loaded
• It is disabled to start with and disabled again when results
with,
come back
• Often contains animated GIF showing progress
• Main use
– Gives user feedback when server-side resource takes a
long time
g
• Note
– You can reproduce indicator region in other places by
using Effect.Show from Scriptaculous
• See later lectures on Scriptaculous
