HTML5 introduces Web Notifications API which “allows alerting the user outside the context of a web page of an occurrence, such as the delivery of email“. This opens up quite a few possibilities for developers like alerting a user when a document needs approval irrespective of the XPage he is currently on.
In this example I will use the Extension Library control Remote Service to poll a view to check if any documents require approval and if yes then show notification to user.

Domino Web Site rules have been around since long before XPages. The Domino Administrator guide defines Web Site rules as follows:
Web Site rules are documents that help you maintain the organization of a Web site. They have two main uses:
- Enable the administrator to create a consistent and user-friendly navigation scheme for a Web site, which is independent of the site’s actual physical organization.
- Allow parts of the site to be relocated or reorganized without breaking existing links or browser bookmarks.
The definition from IBM says that there are “two main reasons”. But if you are familiar with Web Site rules you know that they can also be used to provide connectivity to resources on the file system as well as manipulating the response headers. Those are excellent capabilities and were sorely needed. But in this article we are going to focus on the primary definition provided by IBM and how XPages can provide a little extra help where the Web Site rules begin to conflict and fail.
Web Site Rules Brief Overview
Domino offers four different types of Web Site rules:
- Substitution Rules
- Redirection Rules
- Directory Rules
- HTTP Response Header Rules
This article will focus on the first two types of rules. Continue reading
HTML5 introduces a new API navigator.getUserMedia() which allows web applications to access a user’s camera and microphone. This article on HTML5 Rocks and this question on StackOverflow describe how to use it in your web applications.
In this article I will describe how to use navigator.getUserMedia() in your XPage and save the captured image in your Notes document. As of now this demo is supported only on Google Chrome & Mozilla Firefox on desktop and mobile (I have tested it on Andorid only).
HTML5 introduces <video> tag which allow developers access to user’s camera.
Notice that the <canvas> is hidden.
I am also going to add a text area to my XPage where I will store the Base64 encoded text of the captured image which later would be converted into image using Java (code for that comes later in article). While developing applications you can hide this text area using CSS.
And finally we need a button to take snapshot from camera. Continue reading
