Roller Overview


Apache Roller is the open source Java blog server that drives Sun Microsystem's blogs.sun.com employee blogging site, the US Government's blog.usa.gov, the blogs in IBM's Lotus Connections product, the IBM Developer Works blogs, the Javalobby's 10,000 user strong JRoller Java community site and hundreds of other blogs world-wide. If you want to set up a blog server for yourself or for several thousand of your closest friends, try Roller!

Feature overview

* Wordpress Mu and Wordpress/Lyceum forks provide multi-blog** LDAP plugin exists but is experimental and unsupported


Deployment architecture #1


Deployment architecture #2


Why choose Roller?(Given the dominance of Wordpress)

• It’s the best open source blog server option for the Java platform

• Can be made to work with just about any relational database

• Can be made to work with just about any Java application server

• Proven solution for large multi-user sites


Story of Roller up to 5.0


While at HAHT Software

2001Tuesday, November 24, 2009

I learned about open source


started building something

2001Very early version of Roller, called Homeport at the time, under development in the HAHTsite IDE.


worked nights, weekends and some vacation days too

2001Alex and Linus Johnson taking an morning walk

at Ocraocoke Island, North Carolina - September 2001


made it free


folks started to use it

“I am allowing others to use my installation of Roller for their weblogging. Hopefully this will provide a means for enhancing the Roller user base as well as provide a nice environment for communication and expression.”

Anthony EdenAugust 8, 2002


folks started to help

• Lance Lavandowska

• Matt Raible

• Mindaguas Idzelis

• Jaap Van Der Molen

• Anil Gangolli

• Henri Yandell

• and more...

2002-2004Tuesday, November 24, 2009

Sun joined the fun


I joined Sun


Roller joined ApacheProposal for Roller@Apache

Dave Johnson - Feb 28, 2005

We the committers and friends of the open source Roller Weblogger

project propose that the project become part of the Apache Software Foundation. The rest of this document explains the rationale behind this proposal, how Roller meets the Apache project scope, initial source, resources required, and initial committer criteria.

0 Rationale

Roller is an open source blog server written in Java and originally developed in 2002 for an O'Reilly article titled Building an Open Source J2EE Weblogger. Now Roller is used on multi-user blog servers at the Javalobby's JRoller.com (> 7000 blogs), Sun's blogs.sun.com (>1000 blogs), and numerous other sites. Roller is an open source product, available under an Apache-based license, with 5 committers. Recently Sun hired the original author of Roller to develop Roller and other blog technologies. Sun and the Roller developers want to ensure

Roller's continued success as a viable, growing, open source product. We think that perhaps the best way to do this is to become an Apache project.


Good times...

John Hoffman, Dave Johnson, Simon Phipps, Will Snow and Tim Bray in the back accept a Sun Microsystems 2005 Chairman’s Award for blogs.sun.com and Humanizing the Corporation. Award winners Danese Cooper and Pat Chanezon not present.


Sun contributed a lot

Moved Roller to ASF Roller 1, 2, 3 and 4 Group blogging Planet aggregator Pluggable rendering Pluggable caching JPA back-end Struts 2 migration Configuration system

AtomPub support New template system New macro system UI overhaul Theme packaging Easy install support Memcached caching And much more...


IBM started using Roller

• DeveloperWork: external blogs

• BlogCentral: internal blogs

• And in 2007, launched Lotus Connections including Roller

2005-2007

Sun’s suite never shipped

Media Blogging

• Media file gallery browser with thumbnails

• Media file metadata and feeds

• Easy to add an image to a blog entry

• Easy to upload then blog images






Simple multi-domain

• One Roller instance serves multiple domains

• e.g. my site at rollerweblogger.org serves four domains via the configuration below

# roller-custom.properties

weblog.absoluteurl.photophys=http://photophys.com

weblog.absoluteurl.alex=http://greenimp.me

weblog.absoluteurl.linus=http://linusjohnson.com

OAuth for AtomPub

• AtomPub authentication options now:

• OAuth

• WSSE

• Basic



import com.sun.syndication.propono.atom.client.* import com.sun.syndication.feed.atom.*

def authStrategy = new OAuthStrategy( "roller", // username "55132608a2fb68816bcd3d1caeafc933", // consumer key "bb420783-fdea-4270-ab83-36445c18c307", // consumer secret "HMAC-SHA1", // key type "http://blogs.example.com/roller-services/oauth/requestToken", "http://blogs.example.com/roller-services/oauth/authorize", "http://blogs.example.com/roller-services/oauth/accessToken")

// get the AtomPub service def appService = AtomClientFactory.getAtomService( "http://blogs.example.com/roller-services/app", authStrategy)

// find workspace of my blog def blog = appService.findWorkspace("Blogging Roller")

// find collecton that will accept entries def entries = blog.findCollection(null, "application/atom+xml;type=entry")

// create and post an entry def entry = entries.createEntry() entry.title = "TestPost" def content = new Content() content.setValue("This is a test post. w00t!") entry.setContent([content]) entries.addEntry(entry)

Mailing list activity


What comes next?


Apache Roller 5.0

• Still have work to do

• Testing, debugging, fixing, voting and etc.

• We need your help!


After that?

• Speaking for myself; might be fun to...

• Build a new front-end?• GWT, Dojo, OpenSocial Gadgets?

• Make Roller pluggable?• New plugin architecture, OSGi, Maven?

• Help new contributors?

• Or maybe it’s time to move on.


Avoiding the attic• If we want to

• keep Roller going

• be able to grow community

• be able to make releases

• Then

• we need a couple more PMC members

• we need you to participate

• we need you to contribute


How to help...“The way to join the project is to subscribe to the development mailing list and start acting like a member ask questions, make suggestions, respond to questions, propose changes and submitting fixes and patches.

If you get along well with others, do quality work and show some commitment to the project somebody will most likely nominate you to be a committer.”
