This code iterates through all known factories, searching for one that meets specific criteria for language name and version. In the case of an HTTP GET, this content may be null or left blank. "We said, 'Well, do you have a server with a lot of onboard storage? As shown in the sequence diagram above, the XMLHttpProxyServlet instancehandles the XMLHttpRequest and passes it on to the XMLHttpProxyclient, which calls the service. large, form textarea.
Other scripting languages help to define user interfaces or web content conveniently. The servlet API provides built in support for securing your services or other web resources. What this script does is it forwards to the controller, which handles the rendering of the view. The Phobos project is focussed on building a web application framework that allows you to develop your web applications with a scripting language.
You can usually create new variables without predetermining the variable type, and you can reuse variables to store values of different types. Originally, the Yahoo Geocoder was accessible to JSONP but later the return content type was restricted to XML after the service was severely misused. This approach is pretty flexible in that it gives flexible means to access services.
In the example above  id is the key which is the token passed by a client to  the XmlHttpProxyServlet along with some other parameters such as the location which is needed by the Yahoo Geocoder. This week, I'll describe how I used the jMaki fisheye widget to implement the same use case in a Phobos application.
Page as an application: AJAX techniques can be made to create single-page applications thatlook and feel much like a desktop application.
The CometContext is the main object a component will use to interact with others Comet requests, implemented as CometHandler.
Download GlassFish for which these examples are written to. We'll collect the questions periodically and send them to the experts.
Other developers use the scripting languages available in bash or ksh command shells for both command and job control.
You can restrict access to your services to prevent direct JSONP access in the same way the Yahoo Geocoder by only providing XML formated output. This fact doesn't detract from the power and richness of the Java platform but simply acknowledges that scripting languages have an important place in the developer's toolbox. A client event occurs. The Phobos project is focussed on building a web application framework that allows you to develop your web applications with a scripting language. Mashups: An HTML page can obtain data using a server-side proxy or by including an external script to mix external data with your application's or your service's data.
In the chat example, the polling will occurs after the Servlet.
An HTTP POST requires a Content-Type header to be set on  the XMLHttpRequestobject by using the following statement:req.
Are you using a techniques to restrict access to your services not discussed here? Java EE provides role based security which you can use to restrict the server side resources such as  EJB components, JDBC connections, or web services that your service may expose.
For scalability, it is very important to avoid holding a Thread during the request polling. Page as an application: AJAX techniques can be made to create single-page applications thatlook and feel much like a desktop application.
The servlet API provides built in support for securing your services or other web resources. It is not as strict and more based on the "honor" system as a key could be used in more than one application.
The service then gets the XMLdata and returns it to the XMLHttpProxy client, whichperforms an XSLT transformation on the data to convert it to JSON. A web application contains a static HTML page, or an HTML page generated in JSP technology containsan HTML form that requires server-side logic to validate form data without refreshing the page.
