I came across an application from iReasoning. It was a MIB Browser. When I had my first look at it, i was not able to recognize that it was written in Java. When my folks told me that it was Java, I guess it should be using SWT. No! I was wrong again. IReasoning's MIB Browser doesn't look and feel like Swing. Teh UI was damn good and the response was excellent. I delved into the jars and found that it uses jGoodies.
