Ok, I do not like to write about useless stuff, but this time, I got into deep troubles because one of my clients ask me to implement a portal page on top of JBoss Portal. My first thought was “Ok, if it is as good as JBoss Application Server, it should be good enough”.
So I downloaded it -the 2.7.2 bundled version. I started working on it, simple configuration and customization. I even bought a book, because, I still do believe that books are good for reference.
Oh Dear God! What a SHAME, the book JBoss Portal Server Development [Packt Publishing] is nothing more than printed version of the online Reference Guide. I read the customers reviews before get the book but to be honest, I found websites with useful tips and post. I believe I will donate the book… for recycling.
About the product, I don’ t have enough word to express my frustration.
Content Management
When you read on JBoss Portal documentation it is not a CMS, it really means it doesn’t even work to store content at all.
- CMS performance will decrease dramatically as you load and modifies your content. BIG BIG FAIL! TIP JCR performance gets BETTER if you switch the repo to the FS instead of using databases.
- CMS doesn’ t have Search functionality. Even when JCR has a great index analyser, JBoss Portal fails. I downloaded (svn co) the 2.7.2 version source code from the repos. “core-search” module doesn’t compile. Ant scripts are too fragmented and hard to read. You’ll have to replace and FIX all the jar dependencies to make it work. Note: I didn’t test it, but probably repo works flawless on 2.6.8 version -looking at the scripts and code it could be possible. Once you make it work, the deploy target will not work. Server will consume too memory and then CRASH!
- Portal Pages and CMS content are not related. I built my own search portlet -fragment of code is at the end of this post. It is not easy to match Portal Pages with CMS content -I didn’ t tried it, however I’m pretty sure it is possible.
Documentation
Official docs are good enough -not great but good to be a Open Source project, however Wiki is a shame, its confusing and incomplete. There are a lot of unexplained things like how to get sources, and how to compile, troubleshooting, and stuff like that.
PortalSwap is a FAIL… it is supposed to be a community place to share portlets but there are like four simple portlets.
Community and DevTeam Support
Well, I was contacted -in some how- by the DevTeam on twitter. The truth, I “tweet” my frustration several weeks ago! and they noticed – At the beginning I was angry about the product but then I realized that IT IS FOR FREE, so let’s try to change and improve things! I wrote a nice email to the DevTeam. All I want is to get paid (from my client) and also to contribute to the project.
I’m still waiting for the answer from DevTeam, without mention that the “Twitter Support” was more like a complain than a “Branding Strategy”. So there is no community support, and DevTeam doesn’t know about Customer Care. My suggestion is, next time you contact a frustrated developer, try to convince to “help DevTeam” instead of debate!
As a recap, JBoss AS is a great product, JBoss Portal is seems to me like a “work in progress” – Maybe it is a students project!
Search Portlet Source
The original code have been edited -please let me know if it works for you.

Please THIS IS NOT A PERFECT SOLUTION, but it is a solution. It uses the existing CMSPortlet to display the content -and this approach causes an issue -due to WindowState changes. I hope someone find it useful and improves it. Feel free to contact me if you have any question.
It is curious how all of us take criticism in a bad way. Most of the times, and even more during hard times like this we live now, businesses and partners are criticize every second, like on how they address their customers needs, on how they handle the crisis, on how the company performs financially, on how we react to the situations, and even how senior management is affected -because sometimes senior management is not affected at all.
– they have create their own PHP Framework on top of CakePHP, including JSON and SOAP Webservices and other cool stuff – I’m pushing hard to share most of those nice CakePHP extensions back to the community. You should take a look to their great product once it gets released – check 
I bought a new desktop computer like a week ago, a nice desktop PC with a beautiful 22″ screen. The truth is that I was looking for an iMac 24″, but unfortunately here in Colombia it could be have an overprice of USD$500 ~ USD$1000. So as you can tell it could be a trip to U.S. with an iMac on your baggage. I talked to some of my friends and coworkers asking for somebody to bring it, but it wasn’t possible this time -at least shortly.
