A note from this newsletter's sponsor

Well we didn't quite get to our intended weekly publication mode over the last month, due to being distracted with a number of other initiatives, but we did manage to publish one week, so we'll see if we can do better this month.

In this month's newsletter we list our usual raft of articles, tools, and more. I continued extracting tips from some more JavaOne presentations. I also have a new blog at java.net, and seem to have made the most noteworthy performance news contribution of the month by compiling a list of case studies of successful Java sites (see news below). Included in the list is eBay, serving 380 million pages per day last year, and expected to serve 1 billion per day by 2005. Given that eBay is highly transactional and data dependent, and many of the transactions are the kind that require audit trails, it shows what a Java enterprise site can scale to.

In addition, we have most of our usual sections. Kirk's roundup covers tokenizing, result set processing, data structures, a fascinating discussion on OutputStream.write blocking, and more. Our question of the month looks at whether making an object static to reuse it is good practice; Javva The Hutt reports his holiday surfing adventures; and, of course, we have many new performance tips extracted in concise form.
