A method for serving a web page uses eXtensible Markup Language (XML) server pages. The first time a page is accessed, a given flat file is parsed into an XML Document Object Model (DOM), and required tag libraries are loaded. The DOM tree is then traversed, preferably in a depth-first, inside-out manner to locate custom tags. Upon locating a custom tag, if the tag is registered as a Java object, the object is loaded. A process method is then called on the object, passing the custom tag's tree node. The Java object then examines the custom tag and replaces it with an object, e.g., script code. Alternatively, if the tag is registered as an XSL stylesheet, the stylesheet is loaded and passed, together with the DOM, to an XSL processor. The processor applies the template to the custom tag and replaces it with given script code. Once all custom tags are reduced to HTML and script code, the DOM is compiled into a Java servlet to service the client request.

A method is provided for processing an application on an edge server, wherein the application comprises a set of defined presentation, code and data components, each of which are preferably URI-addressable objects. In response to a client request, the presentation, code and data components are processed according to a set of metadata to generate a response, and the response is delivered to the client. The presentation components are typically content such as HTML fragments, WML fragments, or some combination thereof. The code components are typically Java servlets or beans, XSLT style sheets, or some combination thereof. The data components are typically XML files, native database formatted files, and the like. Each of the presentation, code and data components may have a distinct management profile, cacheability profile, deployment profile, invalidation profile, and security profile. These profiles are settable via metadata or other similar means. Using this framework, heterogenous components may be composed into other components and complete applications or services.

In a traditional application server that uses servlets, when a request is dispatched to a thread the service( ) method of the appropriate servlet is called. When the service( ) method returns the response is sent. This is sub-optimal in the case that an asynchronous event must occur before the response can be sent, because the thread running the servlet must block until the event occurs. The invention provides for asynchronous processing of such requests. In one embodiment, the invention provides an extension to the Servlet API which allows the service( ) method to return (and thus the thread to be freed) before the response is ready to be sent. Then when the asynchronous event later occurs the response may be completed and sent.
