Apparently the javax.swing.tree.TreeNode class is not on the whitelist
for 1.2.6 and Freemarker 2.4 has an evil (IMO) dependency on it.

Monitor Wicket page request using JAMon

Monitor Wicket page request using JAMon

When monitoring these page requests I want to know which page was actually requested. I initially looked at the WicketFilter class as that is the entry point of your Wicket application. However I could not find a way to determine which page was actually requested there. So after a bit of investigation and confirmation from the wicket-user-group (very excellent and active user-group btw) it turned out the that the WebRequestCycle is the class we need to monitor. Wicket provides hooks which you need to override in your custom WebRequestCycle, namely onBeginRequest and onEndRequest. There is one tricky thing though: in the onBeginRequest the name of the requested Page is not yet available, so we need to store the start time of the request instead of the Monitor. In the onEndRequest we can determine which page is requested and can add the measured time to JAMon.

Recherche par facets avec Bobo-Browse

On comprend rapidement qu'il faut fournir à bobo-browse une liste de facet, chaque facet possédant un type, soit SINGLE (value simple), MULTI (valeurs multiple), PATH (valeurs hiérarchique) ou RANGE (interval). On peut ensuite lancer un recherche, ou fixer les valeurs de certains facet, par exemple pour simuler une sélection de l'utilisateur. Si on n'a qu'une facet, fixer une sélection ne sert évidemment à rien (sauf pour les facets de type PATH), mais quand on a plusieurs facets, fixer une valeur permet de faire un drill-down et de préciser les valeurs des autres facets. Aussi, pour les facets de type PATH, fixer une valeur permet de compter les résultats pour les valeurs des sous éléments de la hiérarchie.

IxoraRMS is a tool for gathering and visualizing monitoring data

IxoraRMS

IxoraRMS is a tool for gathering and visualizing monitoring data. It was developed in Java and has a Swing GUI. As part of my job I am involved in performance testing and I felt the need for a tool with the following characteristics:

quick to deploy
able to provide rich amounts of monitoring data
able to automatically update the customized data views when the topology changes
able to provide updates in almost real time
and able to customize the following aspects by writing none or very little code:

adding new monitoring agents
data visualization
adding complex reactions to trigger notifications and tuning/configuration advice

Have a look at the screenshots and go through the documentation and tutorials to familiarize yourself with this tool.

For a list of existing monitoring agents see this page in documentation.

Closure Tools (Labs)

The Closure tools help developers to build rich web applications with JavaScript that is both powerful and efficient. The Closure tools include:

The Closure Compiler compiles JavaScript into compact, high-performance code. The compiler removes dead code and rewrites and minimizes what's left so that it downloads and runs quickly. It also also checks syntax, variable references, and types, and warns about common JavaScript pitfalls. These checks and optimizations help you write apps that are less buggy and easier to maintain. You can use the compiler with Closure Inspector, a Firebug extension that makes debugging the obfuscated code almost as easy as debugging the human-readable source.

cloudloop is a universal, open-source Java API and command-line tool for cloud storage, which lets you store, manage, and sync your data
between all major providers.

Supported Providers
Amazon S3
Nirvanix
Eucalyptus Walrus
Rackspace CloudFiles
Sun Cloud
Microsoft Azure
EMC Atmos
Aspen
Diomede

never lose access to your data.

sync your data to multiple providers, so if your primary provider goes down you will still be able to access your data.

easily switch between providers.

cloudloop makes switching between storage providers really easy. there are no code changes required to move to a new provider.

organize your data.

cloudloop lets you organize your data with a standard directory structure, rather than key-value systems offered by most providers.

use a familiar interface.

cloudloop gives you a powerful unix-like command line interface for managing your data and configuring applications that use the cloudloop API.

Creating Oracle Database-backed iGoogle Gadgets

Learn how to build gadgets for iGoogle and OpenSocial containers that read data from an Oracle database.

Gadgets within personalized home pages are an interesting channel to distribute information and extend the reach of Web applications. As we work more and more on "extended enterprise" or enterprise 2.0 applications, enterprise developers are looking for new ways to reach our users, and to integrate within the flow of information that the user is otherwise receiving.

In this article you'll learn how to use an Oracle database (with its native support for HTTP and XML) as a backend for a Google gadget. We'll do this while building a few simple gadgets that pull data from the database, and using Oracle XML DB to host associated static files. No prior knowledge of the Google gadgets specification is needed and all of the examples have been tested on Oracle Database XE (and will probably run on Oracle Database 11g as well).
