And another thing... Tim Quinn's Blog

As we are working on the support for app clients in GlassFish v3, I've posted a "request-for-opinions" in the GlassFish forum.

Rather than repeat it all here, please go visit the topic.  If you develop app clients please take a few moments to add your thoughts as replies to the forum topic there (not to this blog). 

Supporting new types of applications in GlassFish v3 is as easy as 1...2...3...literally.  Implement three interfaces GlassFish prescribes, package them as an OSGi module accessible to GlassFish, and then you deploy and run apps of the new type.

I've just completed the process of writing, with the able help of Rick Palkovic, a new article on Java Web Start support for app clients in GlassFish and publishing it in the technical articles section of java.sun.com.  

Those of you who have read this blog routinely probably won't find much that is new there, but as always we're trying to reach a broader audience and promote the use of app clients in general and the Java Web Start launch feature in particular.  This article should help!

 

 

Many users have encountered problems on Windows when JAR files remain open, causing problems during undeployment and redeployment. Recent changes to GlassFish will resolve many of these difficulties.[Read More]

Open source and product support are not mutually exclusive. In this brief tale I describe a recent experience that shows that people can get good support (lower-case "s") from the community and yet paid Support (upper-case "S") from a product vendor has its own added value.[Read More]
