mapleBlog is a simple MVC Struts 1.1-based Web log that uses Hibernate as its model layer and Tiles/JSP for its View.

It is relatively simple to configure and has full basic functionality. By using Hibernate, it is able to function with a wide variety of databases.

Can also easily be replaced by entity beans and EQL due to the façade used to cover all database activities. Although entity beans are dog slow.

blog was a concept I came up with after working on a project for a client and it seemed like other people needed the same software. Instead of the ever-increasingly long series of one dimensional postings that form most web journals, blog divides the journal up into topics (called threads) and postings (called entries). blog groups topics, sub-topics and posted messages in a way that allows an intellegent browsing mechanism. blog would also work very well as a categorized FAQ or press release archive.

Technical Details (Summary):

Type of Software: API (Abstract Programming Interface)
Programming Language: Java
Platform: Any (its Java)
Required Software: Any Java 1.1 compliant Servlet Container (no, its not a servlet, but you'll need one to use blog).

JSP Blog was created due to the fact that I could not find an Open Sourced JSP weblog. I found plenty in PHP, however none in JSP.

This project was initially conceived by Anthony Ehrhardt. I am a professional UNIX Engineer with 12 years of experience with UNIX and 6 years of Linux. Linux is my OS of choice.

jsp blog : A personal blog (weblog) that is written in 100% JSP. Made on Apache Tomcat and MySQL. Will ultimately be 100% cross-platform
