Java News from Tuesday, November 30, 2004

The Cafes seems to be off and running. There were a few initial glitches that I have now cleaned up. There's some interesting discussion in the comments fora for On Iterators and Indexes and Overloading Int Considered Harmful. Today's project is to make the staging server work enough like the production server that I can use it for testing and debugging without affecting the production server. Yesterday I got stymied by a slight difference in how the PHP engines were configured. (The staging server didn't have libtidy support that the site relies on heavily.) I had planned to post a backlist article today, but instead I found myself forced to think about spam.

Sleepycat Software has released Berkeley DB Java edition 1.7.0. Berkeley DB JE is an open source, non-relational embedded database written in Java.

Java 1.4.2 or later is required.
