Minimal portlet environment for developing? - liferay

At our company we are using Liferay for portals. My biggest issue with developing for such a huge framework is that the restart takes a lot of time even on a decent PC. We're trying to use hot deploying were it's possible but this sometimes just doesn't work (dependencies require restart, PermGen space errors occurs sometimes and Liferay have to be killed, etc.)
What i'm thinking about is that with most of our portlet's we are not really using any Liferay specific services just the JSR 168 provided things which is a standard. So i'm wondering if there's any minimal portlet environments available for Jetty or Tomcat which we can use for quicker portlet development? Of course i know that once i encounter a Liferay specific service call this is not an option.
I was testing Apache Pluto earlier which is a full blown but still lightweight portlet container however it works differently the way the portlet wars are assembled (web.xml should be modified) and it breaks compatibility in our build environment with Liferay. So it's not an option but i'm looking for something similar.

I've never used life ray portal, but too much played with GateIn portal because IBM Portal is heay, mostly for quick development on JSR-286 i used gatein
Currently used for visioneo.org, very flexible for every kind of use, large community.
Here is short summary
Liferay Currently used for visioneo.org, very flexible for every kind of use, large community.
eXo Platform Awesome look and set of web applications embedded. Last generation portal, very impressive! Based on Gatein
JBoss EPP Based on gatein, and designed to work with JBoss middleware architecture
Gatein A great portlet container. Light weight, easy to use. But unlike Liferay and eXo, it does not ship with collaborative portlets (Forum, Wiki etc.)
uPortal Beautiful portal, though its CSS are very intrusive: some BIRT styles are broken by uPortal's css.
Pluto Not really a portal, Apache Pluto can be used as a development / test platform. Often considered as a reference for portlet specifications.
Jahia Great look however not based on standards: portlets are supported but not really highlighted, a specific module technology is used instead

You might want to try the JRebel integration for Liferay. There's an introduction Webinar available, I don't know if it fully applies to the current implementation (the webinar is a bit aged) but it will give you an idea of the product/project.

How is your approach for creating your own set of controls aka own Extensions Library?

What is your approach for creating your own set of controls aka own Extensions Library? After a few years of Xpages development we have a huge set of controls that are general purpose for building UI, some web services etc. (Probably as most other developers.) When we start a new project now we have to copy the entire stuff from one database to new one which involves controls, jars, css, images, JAVA code ... and then you completely loose control to maintain some central version of this controls & codes, everything is scattered among several projects/databases and things get messy fast.
We have thought about creating our own extension library as described here
http://www-10.lotus.com/ldd/ddwiki.nsf/dx/Master_Table_of_Contents_for_XPages_Extensibility_APIs_Developer_Guide but there is not enough documentation for this topic and the entire development process is quite complicated (at least seems to me. I tried two times based on docs above going through eclipse plugin project -> feature project -> update site and still having some bugs around)
What is your experience and approach for creating and maintaining shared Xpages controls in your Domino environment? Is there some hidden feature we miss here that can help us?
Take a look at the XSP Starter Kit on OpenNTF and the XPages SDK to setup an eclipse environment for plugin development. You'll also want Eclipse IDE for RCP and RAP Developers. Install the starter kit and SDK into eclipse and you should be all set.
The starter kit is a sample plugin with all kinds of examples of phase listeners, components, etc. Once you want to deploy your plugin, create an update site from within eclipse and use the Update Site NSF available on your server install to place your update site. Once that's done, you can replicate that NSF to any other servers that may need the plugin.
For more information about the starter kit, take a look at this slide deck. There is also a github project for the starter kit. Documentation for the XPages SDK can be found here. And a video for setting up the SDK is available on youtube. Lastly, here's the documentation for setting up the update site NSF.
While we haven't gotten to that yet in XPages, our model for regular Notes design elements is to have a central template that contains the elements that are shared, with those specific design elements marked to inherit from that template. Sometimes, a database inherits design elements from two different central templates.
That way, those centrally controlled design elements remain the same in all databases.
I would recommend looking at some example's on github for how they have library/components setup. One of the more simpler examples that has just a single component built into a Library is Steve Pridemore's App Layout Extension...https://github.com/DominoDev, Another good one is Nathan Freeman's Starterkit: https://github.com/the-ntf/xspstarterkit. Hopefully these will help you get the file structure down on which files you need and how they work.

entreprise intranet Liferay or Alfresco

I want to create an enterprise intranet , that provides authentication of employees and management profiles, messaging, calendar, document management...
I think I can use php or java CMS , for the moment after some research I decided to use Liferay or Alfresco. The problem is that I don't really know the difference between them , and what I have to choose .
They're quite different products, solving different business needs.
Liferay
It's a Java Portal. It focuses on creating web sites that are able to integrate data coming from different sources and applications in the same page. Using portlets, you compose a page to enrich it with such mini applications. It's mostly used to create web sites that aggregate information and contain interactive features such as online chat, blogs and the like. It also provides document management as part of its features, with the possibility of integrating Alfresco as a backend.
Alfresco
It's an Enterprise Content Management system. It revolves around documents, their lifecycle and collaboration capabilities over such documents. With the advent of Share, Alfresco now offers a lightweight portal-like application that lets you place "dashlets" in both an User Dashboard and a Site Dashboard (sites are shared workspaces).
While you can have non-document centric dashlets, blogs and wikis, they're not extremely sophisticated, and most of Alfresco features focus on document management and online collaboration.
I have not worked with portals for quite a while, but I guess the answer is : It really depends. :)
Seriously, in your requirements context I would compare Alfresco Share with Liferay. Both compose pages in a similiar fashion with Webscripts/Portlets components and have security baked in.
I think the most important factor to consider is your skill set.
If you feel at home with Java, the Portlet spec and server side logic : Lean towards Liferay. Alfresco Share/Spring Surf should serve you better if you prefer Javascript in the browser and JSON/REST style programming.
Besides, validate how strong your document management requirements are.
Do you really need super sophisticated search, workflow, versioning, security and the like ?
Sophistication increases complexity. That is also why I would be careful before introducing them both at the same time.
Another point to have in mind may be documentation - guess this point goes to Liferay.
Liferay's primary strength is as a portal where you use existing "applications" to fit your need, or create your own using the Portlet spec. Alfresco is a CMS, so it focuses on content management.
Why not use both?

Examples of Struts2 applications

I am working on a static analysis for detecting security vulnerabilities in web applications, and I am looking for some web applications to run my analysis on.
More specifically I am right now looking for open-source web applications that use the Struts2 framework, but I have a hard time finding such applications.
Does anyone know of some more or less complete and open-source web applications written using Struts2 (or possibly just plain JSP)?
The very complete and stable Struts2 application i use for log file analysis is KonaKart. The advantage is that you can set it up on your server, including demo data and configure it and use it as you wish.
In terms of openness:
"Only the customizable parts of KonaKart are open source. These include the Struts action classes and
forms, the JSPs, the payment modules, order total modules, shipping modules and the GWT One Page
Checkout code. They are shipped under the GNU Lesser General Public License."
If you need 100% open source it is not for you.

Simple CMS for building a small company presentation-website

I'm looking for a free, simple and efficient CMS for building website for a small company.
Prerequisites are:
The website is nothing more than a presentation - with informative content and gallery. The website should contain a nice-looking gallery with js/ajax flavour. Nothing more is planned for now, but it would be nice if CMS would feature some more generic modules/extensions in case I would like to use them in future.
Design templates should be easy to adopt and change.
Coding as little as possible.
I thought about Drupal, but is there any other CMS which would better fit to these requirements?
Please don't list available CMS-es here. Give it a reason!
Wordpress is nice too :p It has a big community behind...
I say Drupal.
Drupal is really good in content management. You can create different content types, and assign them fields (in Drupal 6, you will need the CCK contrib module). You can create a gallery with Views and it's output plugins. There are dozens of them, using different layout and JavaScript effects (mostly different jQuery plugins, but there are plugins for lightbox and thickbox also).
Drupal has a group of themes called "starter themes". These themes are half-ready, and it is very easy to create your own custom themes with them. All you need is to create a subtheme. (Basically making an info file and copy some other files. There are really a lot of howtos out there.) There are also starter themes for 960 (CSS framework), so you can make the site layout really fast. The most famous starter theme is called Zen. You might want to use that.
Except for the theme, I don't think that you have to write any code. Writing a theme for Drupal is not hard, since it uses PHP to render the themes.
Still in beta (0.5) phase but looking very promising: Orchard, a new ASP.NET MVC based CMS created by the people from Microsoft.
Orchard will create shared components for building ASP.NET applications and extensions, and specific applications that leverage these components to meet the needs of end-users, scripters, and developers. Additionally, we seek to create partnerships with existing application authors to help them achieve their goals. Orchard is delivered as part of the ASP.NET Open Source Gallery under the CodePlex Foundation. It is licensed under a New BSD license, which is approved by the OSI.
The intended output of the Orchard project is three-fold:
Individual .NET-based applications that appeal to end-users , scripters, and developers
A set of re-usable components that makes it easy to build such applications
A vibrant community to help define these applications and extensions
In the near term, the Orchard project is focused on delivering a .NET-based CMS application that will allow users to rapidly create content-driven Websites, and an extensibility framework that will allow developers and customizers to provide additional functionality through module extensions and themes.
It depends on what kind of CMS you are after
pity you don't like programming otherwise i would suggest django, an awsome CMS framework
if you are after something simple like a few static pages and a news feed or something like that then wordpress might suit your needs well, except i have found i don't like how it handles gallery's
if you need anything more, like more advanced custom content types for products, i would recommend Joomla or Drupal, and have plug-ins that has good support for photo galleys
Joomla! will probably be a better choice. It is very easy to use and is highly extensible.

Liferay Portal : How different from Websphere Portal

I have worked with Websphere Portal 6.0,6.1 and developed portal applications usign JSR 168,JSR 286 Portlets.
Now I am moving to project where I will be working with Liferay portal server and JSR 168,JSR 286.
I know that as per programming interface (JSRs) It will be the same. But want to know what are the major difference at server level ( features,configuration,architecture, out-of-box services) when compared to Websphere Portal ?
Thanks
Liferay also supports JSR168 and JSR286 portlets, so in respect to that you can use the same API's as you are using in WebSphere Portal. The product itself cannot be easily compared to WPS as they both have different concepts. Liferay doesn't have a credential vault, for example, but it still supports SSO (NTLM or CAS). Your WebSphere Portal knowledge won't help you much in Liferay development, as it is a totally different product.
I agree the configuration will be different but I think it will help a lot the fact that you are prepared to think about the information architechture.
The main difference is that Liferay is not really that much prepared for escalability. It uses velocity so neither of the tags you use will help (Placeholders, component, element, etc).
It doesnt have that many portlets by default so you will have to develop a lot from the starter point.
Check this out for a really nice comparision (the slides are in spanish, and require the flash plug-in):
http://www.slideshare.net/mcimino/websphere-portal-vs-liferay-by-gartner-v10
Basically Liferay weaker points are in B2C and support. If you need to build a site that will rely heavily on personalization, you will have much work to do too.
Hope it helps
