In previous articles, I have described the concept of an Inter-Portlet Communication (IPC) framework, its technical details in portlet configuration, and the IPC framework in live action. In this article, I will try to describe how a good IPC framework can affect design and development model. Inter-portlet communication framework is a messaging middleware for portlets. [...]
Through a few real use cases, this paper describes the IPC mechanism in live action. The paper describes in details how to create page flow by chaining pages together using portlet communication.
Previously, I have proposed a new framework for Inter-Portlet Communication (IPC) to remedy the shortfall of the Java Portlet Specifcation. In this paper, I will describe the technical details on how to define IPC in portlet configuration.
IPC is the communication mechanism between different portlets on a portal platform. This paper describes the concept and framework of a proposed IPC mechanism, and the different use cases for portlet communications.
Ok, Java 7 is not out yet, but as a programmer, aren’t you eager to try it first hand? Here’s how to add Java 7 to your NetBeans IDE, and get a feel of what is coming up. Go the OpenJDK web site to grab the latest build of the JDK 7. If you have [...]
All Java programmers have run into, one time or another, the problem where a specific class is not behaving like it is supposed to. After banging your head on the monitor countless times, you suddenly realize that the wrong version of the class file has been loaded, and you start to track down which jar [...]
This is probably old news as this feature has been out for a quite a long time, but I’d like to say to big thank-you to the NetBeans developpers to come up with a nice, very intuitive debugger for debugging multi-threaded applications in NetBeans. Kudos for the good work. As I’ve said in a previous [...]
As IC card’s use becomes more widespread, and even more are used for transaction, authentication, data encryption and decryption, key management of a distributed IC card system becomes a critical security issue. Although the traditional way of asymmetric key management and exchange is more secure, however, it is more complicated to manage, and requires more [...]
Curiously, NetBeans has included Java API documentation for a lot of packages, except the API documentation for the Java platform itself. Here is how to add the JDK Javadoc to NetBeans: Download the Java API documentation package from here. Unzip the documentation package. In NetBeans, select Tools > Java Platforms Select your default JDK in [...]
After using Eclipse almost exclusively for Java programming in the last 7 years, and put up with its different problems, which seem to pile up over the years, I finally took a jump and installed NetBeans 6.8 to see how it’s doing recently. The event that triggered the switch was an upgrade from Ubuntu 9.10 [...]
