Adam Sanderson emailed me a while back about his alerting framework for Java. I had meant to include it in the daily links but somehow got side tracked. So Adam ... sorry about that. Instead I'll give Perkup its own blog post.
Perkup Java Alerting Framework
Perkup is a Java library designed to show non intrusive alerts to user. The library is simple enough that it can be invoked with a single line of code:
Notifier.getDefault().alert("Hello World");
This would send a popup alert to the user. PerkUp is also configurable enough that a developer can create unique alerts, and alerting mechanisms. For instance, although the two current notifiers use Java's Swing for GUI notifications, Notifiers could be written for AWT or IBM's SWT. It would even be possible to integrate non visual technologies such as FreeTTS to create voice notifications.
