This second screencast of the Creating Mashups with jMaki Series show how jMaki allows to embed and interact with map widgets in your application. This screencast shows how to creates two mashups - the first one is where a city location is keyed from name and displayed in map widgets from two different toolkits, and the second one shows how to extract data from Craig's List...

As reported earlier jMaki and GlassFish, along with a host of other Sun-led open source technologies (NetBeans, OpenJDK, OpenDS, Project Indiana, etc.), were present at OSCON 2007 last week. I spent my entire 2 days at the jMaki booth which had a consistent stream of visitors on both the days. In case you are interested, here is what I presented: What is jMaki ? Running...

The jMaki data models have been formally specified and as of last week, build .9.6 implements all specifications. The data model pages include the formal specification of the data expected by the widgets. They also include information about the event types and payloads published by the widgets as well as the event types and payloads expected by the widget subscribers. You will find lots of...

Widgets talking to widgets has just become a lot easier in jMaki. The .9.6 build or first Release Candidate fully supports the data models we have recently specified. You will find the formal specifications on the wiki model pages. We wanted to specify the data passed to the widgets so users know what the widgets expect when loading data. We found that the models also need to describe the...

A jMaki widget in a page can communicate with: Other widgets on the same page using publish/subscribe mechanism Services in the application domain using service="data.jsp". Services outside the application domain using proxy (xhp). This blog entry explains how external services can be accessed by jMaki widgets. This image shows a Web application with multiple pages (Page1...

I am visiting the web pages worlds these days - I confess it is not my metier, but this html trip is unveiling nice tools to minimize your the stress about validation and performance of web pages. One of the hard tasks related to web performance is the large amount of details that can affect the usability round trip (request-server processing-response-browser rendering). During my preliminary...

What is jMaki ? If you have been following my blog, then you know it already. But a picture is worth a thousand words so here it is. One-liner: jMaki is a light-weight framework for building Web 2.0 applications. The "j" is for JavaScript and "Maki" means to wrap in Japanese. The logo is a Kanji symbol that means to wrap. Three key points about jMaki: Toolkits - It allows...

jMaki provide a flexible framework to create mashups very easily. Today, I'm starting a series of screencasts that will focus on this aspect of jMaki. The first one in the series is a very simple mashup that pulls RSS feed from a blog entry and display it in two different widgets, without any extra effort. The NetBeans IDE is used for tooling and the jMaki-enabled Web...

jMaki allows filter to be configured on a widget. A filter is a JavaScript code fragment that performs data conversion from one object format to another. This allows a widget to consume data from multiple services outside the application domain and transform the received data into a standard data model. There are several pre-defined filters in system-glue.js, for example jmaki.filters....

Once in a while people blog about JSP being a dead technology. Well, that's not true, it is so alive that it is even being sold in the streets of San Francisco, as shown below: I saw that place yesterday night, when I was walking home, after watching a movie. Unfortunately I didn't have a good camera with me (my cell phone does not have a flash), but thanks to Google Maps Street View I could...
