Jackrabbit + rtf template: A tailor made application with embedded Template and Document Management

We are working on a webbased solution to generate documentby merging some dynamic data from an RDBMS into templates. We opted for rft template (http://rtftemplate.sourceforge.net/) and JackRabbit (http://jackrabbit.apache.org/) to build the solution. Being 100% embeddable we aim to give a really tailor made solution to our customer while simultaneously reusing the power and functionality of these really well designed libraries.

Migrating from Websphere 6 to Tomcat 6

Last year we took up a project to migrate a J2EE infrastructure from Websphere 6 to Tomcat 6.
The applications are written using Struts and POJOs that access Stored Procedures on AS/400 via JDBC.
It took us just 4 days to complete the migration of 8 fairly complex applications.
4 Tomcat instances running on 2 Linux servers are load balanced via Apache 2.2 + mod_jk.

We have developed a custom application for the sysadmins to centrally manage all tomcat instances.
The application makes use of the tomcat manager application and JMX to control and monitor the tomcat instances

To complete the puzzle we are now testing our Terracotta to apply session replication to gain even higher avaliability!

So far, so good!
