What’s hot? Tech Trends That Made a Real Difference in 2017

At Java One 2017 I had the pleasure to be interviewed in a podcast with industry legends such as Chris Richardson, Lucas Jellema and others:

“In order to get a sense of what’s happening on the street, we gathered a group of highly respected software developers, recognized leaders in the community, crammed them into a tiny hotel room in San Francisco (they were in town to present sessions at JavaOne and Oracle OpenWorld), tossed in a couple of microphones, and asked them to talk about the technologies that actually had an impact on their work over the past year. The resulting conversation is lively, wide-ranging, often funny, and insightful from start to finish. Listen for yourself.”

For those who care, this was last year’s interview about “The Role of the Cloud Architect”.

Java Class Not Found Exception / Could Not Find Class

Class Not Found

Could not find or load main class

You compiled your Java HelloWorld.java and then you are facing an error? Most likely you added the .class extension when the running the programm:

$ java HelloWorld.class
Error: Could not find or load main class HelloWorld.class

You were running the .class file. Try again:

$ java HelloWorld
Hello, World

Deal with ClassNotFound Exception

If you encounter a class not found exception while working with Oracle WebLogic server I recommend my posting about the Classloader Analysis Tool.
