I put the service release 5 of JDK 1.5 and Tomcat 5.5 on the server today.

The Tomcat 5.0 was bundled with the JBoss installation previously put on the server, but the JDK was still v1.4. I want to press the envelope when I can, because I find I have gaps in maintenance and sometimes the versions skip quite a few before I get a chance to upgrade.

The JDK install didn't work remotely (I have no SSH access, so I have to use the tools provided by Webmin, which offers a "command line" tool, but it's not interactive. Handy for downloading, moving, and otherwise managing archives and files, but they've got to be interaction-free.

The Tomcat installation was done remotely, as it's generally un-tar, edit, copy, and execute the startup script. I got the JBoss configurations for the virtual domains configured in the Tomcat installation, but v5.5 wants JDK1.5, so I had to wait to fire it up.

The server's now running Tomcat by itself, without the wrappings of JBoss. I may turn the tripping around, but since the only bit I was using from JBoss was Tomcat, it seemed a huge memory hog. When I get my EAR needs up to speed, I'll switch back. Maybe by then JBoss will support JDK 1.5.
