Subject [jira] [Updated] (HBASE-3835) Switch web pages to Jamon template engine instead of JSP
Date Tue, 03 May 2011 07:04:03 GMT

     [ https://issues.apache.org/jira/browse/HBASE-3835?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Todd Lipcon updated HBASE-3835:

    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? :)

> 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.
