First of all, regarding name of the blog.... While not all the posts in this blog may be around java/j2ee; most of them will be. "Oak" & "Green" are x-names (!!!) of what is today known as "Java" programming language.
This is my second blog on tech-stuff but this is different from first one (teKNOWlogy.blogspot.com). The earlier one mostly talks about Biz side of technology - primarily startups, whereas this one is for stuff around development, primarily Java/J2EE stuff.
