After more than a decade in the Java universe, today I had just enough of remembering where my executable JARs are located and typing all the lengthy path names, so I finally taught Windows to deal with Java archives just the same way as it deals with it's native executables EXE and CMD. The trick is so simple that I actually do not understand why the JRE installer isn't applying it automatically...

Apache maven is supposed to solve the classpath hell; or so I´ve been told...

I was uploading my Amazon image for the 3rd time. First time it didn't boot, second attempt I couldn't log in via ssh, third attempt , success! Admittedly the bundling didn't take too long for a 10GB file, and even the upload on our work network (this was an S3 image) wasn't that long but 'm sure I wasted a good few hours.
I did my obligatory google and came across a few ideas. First...

My first session this moring at JavaOne was Deploying Java Applications on the Web. It was quite good as it covered some of the newer techniques that have been added to the latest 1.6_x updates. As with any good session, I walked away with some knowledge that I hadn't entered with, but what struck me the most was the legacy of JavaFX. While JavaFX was mentioned (in passing once...
