The other day I
wrote about using annotations to state your intent regarding null for fields, parameters and return values. This can help static checkers like
findbugs find flaws in your code, where you fail to check return values for null where that is known to be risky. (In fact, findbugs does not only base knowledge of nullness on your use of annotations; it also has a builtin database of...

This is just quick a pointer to a great blog entry I came across written by Gregory Murphy (from the Creator team) which tells you how to work with resource bundles in Creator. Until now, writing a web application with proper resource bundle lookups has meant giving up some WYSIWYG aspects, because the tag is not interpreted at designtime. But with Gregory's solution, we finally have a...

One pattern I've seen some developers use is to respond to NPE (NullPointerException) bugs by inserting a null pointer check at the location of the NPE. Frequently this will be accompanied by some sort of comment like "Why is this null?".
My advice is simple: Leave the NPE until you've investigated...

I love to write code, but there seems to be a bias against that skill in senior software positions. Perhaps it's a holdover from the sixties when system analysts were held in higher esteem than programmers. Not much COBOL gets written these days, so why is that attitude still prevalant?
