[jira] [Created] (HBASE-3835) Switch web pages to Jamon template engine instead of JSP

Switch web pages to Jamon template engine instead of JSP
--------------------------------------------------------

                 Key: HBASE-3835
                 URL: https://issues.apache.org/jira/browse/HBASE-3835
             Project: HBase
          Issue Type: Improvement
          Components: master, regionserver
    Affects Versions: 0.92.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
             Fix For: 0.92.0


Jamon (http://jamon.org) is a template engine that I think is preferable to JSP. You can read an interview with some comparisons vs JSP here: http://www.artima.com/lejava/articles/jamon.html

In particular, I think it will give us the following advantages:
- Since we'll have a servlet in front of each template, it will encourage us to write less inline Java code and do more code in the servlets.
- Makes proper unit testing easier since you can trivially render a template and pass in mock arguments without having to start a whole HTTP stack
- Static typing of template arguments makes it easier to know at compile-time if you've made a mistake.

Thoughts? I converted the Master UI yesterday and only took a couple hours.

    Attachment: hbase-3835.txt

Here's a patch which moves master and region server both to servlets with Jamon-based templates.

I didn't do zk.jsp yet. Maybe someone else wants to try it to get the hang of jamon? :)

Yea, I was planning on moving some more pages over if people seemed to like this choice. Let me ping the dev list and make sure a quorum of committers is on board, since it's something we will live with for a while.

I stumbled upon this accidentally. I hope you didn't include the linked license to NOTICE.txt, since JAMon != Jamon. The former is a monitoring tool, the later is said template language. It is published under Mozilla Public License.
