Learn how to develop for Android, Beyond HelloWorld
Marko Gargenta delivers a tutorial-style talk on how to develop for Google’s Android platform (beyond the HelloWorld) at the San Francisco Android User Group.
Oracle OLAP Option
The Oracle 10g Enterprise Edition OLAP Option extends the analytic capabilities of the Oracle database by providing new multidimensional datatypes, a multidimensional calculation engine, and a framework to build OLAP applications using SQL, PL/SQL and Java. Uniquely, the OLAP Option uses the Oracle database to store and manage its data, allowing you to take advantage of the scalability, reliability and manageability of the Oracle 10g platform.
How To Create an IE-Only Stylesheet
The tool of choice for fighting IE problems is the conditional stylesheet. IE provides comment tags, supported all the way up to the current IE 8 to target specific versions, as well as greater-than/less-than stuff for targeting multiple versions at once.
Why use conditional stylesheets?
- You got problems, they need fixin’
- Keeps your code hack-free and valid
- Keeps your main stylesheet clean
- Perfectly acceptable technique, sanctioned by Microsoft
1. Create a stylesheet and javascript common for all browser, without using any hacks to work around rendering problems in MSIE
2. Create a stylesheet and javascripts common for all versions of MSIE.
3. Create a separate stylesheet and javascripts for each of the MSIE versions you want to target.
4. Include the stylesheets and javascripts from 2 and 3 by using conditional comments.

Inject Google analytics code in HTML pages
To update your HTML/JSP/PHP pages with the google analytics you can
use UNIX sed command and inject the two scripts provided for your
website by google analytics. Below is the code. This code replaces
</body> tag with the scripts and </body> tag.
find ./ -type f -iname “*.htm” | xargs sed -i ’s/<\/body>/<script
type=\”text\/javascript\”> var gaJsHost = \(\(”https:” ==
document.location.protocol\) ? “https:\/\/ssl.” : “http:\/\/www.”\);
document.write\(unescape\(”%3Cscript src=’\”” + gaJsHost +
“google-analytics.com\/ga.js’\” type=’\”text\/javascript
‘\”%3E%3C\/script%3E”\)\);
<\/script><script type=”text\/javascript”> try { var pageTracker
= _gat._getTracker\(”UA-XXXXXXX-X”\); pageTracker._trackPageview\(\);
} catch\(err\) {}<\/script> <\/body>/g’
Reduce code noise with Groovy
Groovy’s concise syntax frees developers from typical Java™ constructs that are required for code compilation but don’t facilitate expressing what a program is really trying to accomplish. In this revival of the Practically Groovy series, Groovy developer and guest columnist J. Scott Hickey walks you through a series of comparisons between normal Java code and the same Groovy code to show you how this exciting language frees you to focus on the important aspects of coding.
JBoss ESB
If SOA is too expensive, complex or politically challenging, the technology won’t take off. How, then, is it possible to build an SOA that overcomes political and cost constraints? Driving an SOA strategy to success in a large organization requires a corporate-level CIO with the power to drive a vision, enforce a set of architectural goals and blueprints, and mediate financial allocations. To get a manageable SOA, you’ll need to start with SOA platforms that represent a relatively low investment. That’ll likely mean tools and platforms that are open source, with support and ecosystem benefits available at a low cost.
JBoss team have designed their own Service Bus: JBoss Enterprise Service Bus is a robust SOA solution designed since the release 4.2 with build-in fail-over, load balancing and delayed message redelivery. JBossESB allows you to distribute service instances across many nodes. Each node can be a virtual or physical machine running one or more instances of JBossESB.
How to use the agent sample application in WebLogic 10 - OpenSSO
This document describes to use the agent sample application in conjunction with the Weblogic 10.X Application Server and the J2EE Agent. Please note thatthe agent needs to be installed first before deploying this sample application.
OpenSSO Fedlet Demo
I will try to demonstrate an IDP generating Fedlets, SP configuring and using this Fedlet for IDP initiated SSO, SP initiated SSO and transfer of identity attributes as part of the assertions from the IDP.
Here’s also the details and a write-up of steps of steps, which I’ve used for the setup.
Using Adobe Flex in JSR-286 Portlets
This article shall show you how the Adobe Flex SDK can be used in a Portal environment to enhance the user interface for a Portlet. It has also previously been possible to use Flex with JSR-168 Portlets and alike [FlexPortal], but with the new Portlet 2.0 specification (JSR-286) some things have improved, such as the support for asynchronous requests, public render parameters and events. It will be shown what is possible with the technology combination Flex/Portlets and where the limits are.
JBoss Federated SSO
The JBoss SSO Framework is a collection of components that software developers can easily integrate within their existing web applications to create a federation of trusted web sites. The framework has support for important SSO standards such as SAML.
