Until now when the user was in any place of the portal  clicked the "Sign in" link he was shown a default portal login page. Of course it was already possible to create your own customized login page using the available portlets, but the user was not redirected there when clicking the "Sign in" button. After this improvement it is possible to let the portal know that a given...

Hi everyone. Yes, now you can develop portlets using groovy, and thanks to the last changes made by Brian is quite simple. Let's take a look at sample-groovy-portlet (check it out from the plugins svn). The file structure is like this: All the impotant files are under docroot/WEB-INF. There you can see usual files, including portlet.xml, which looks like this ...

This is a feature I know many of us have been desperately wanting for quite a while. In fact, it's something that many of us miss from other blogging apps, and we now have it. So, to kind of show off what we have, I'll include screenshots from this very blogging session. Notice the time? Every ten seconds, we automatically save your draft until you click publish. This means...

Portals are all about personalization, and Liferay is no different. I mean, there are many, many other things involved in portals other than personalization. But none of them really make sense without it. Personalization is the dressing that makes your portal salad bearable. So, it has to be pretty good dressing. Beyond the portal and personalization, we have the...

I picked up a copy of the International Herald Tribune while boarding my flight for Rome where I'm helping a client launch their new social computing platform this month. I had heard about the devastation in Myanmar that happened now over two weeks ago, but it wasn't until Wednesday morning of this week that what happened really hit me. A photo on the front page of the Tribune showed...

Many people ask how to achieve file downloads from a portlet project. I'm going to try putting this mystery to rest by first explaining the limitations and then showing some old and new ways of overcoming them in Liferay. To be clear on terminology we'll call anything, other than the usual presentation content, that we want to deliver to the user a resource. Examples of...

Liferay enjoyed a great JavaOne this year, our third corporate appearance at the ground zero of the Java development world.  The emphasis this year was on openness, community, and the individual, reflecting the transformation our industry and culture have gone through over the last decade. In IT, that's been reflected in a shift from proprietary solutions controlled by the few to...

If you are or you have tried installing a Liferay on a cluster of Ubuntu machines and are/were having problems with the ehCache, do this check:]$ ping `hostname`If it responds using an address on the loopback device, there's your problem.By default, Ubuntu defines the machine's hostname on the loopback address (127.0.1.1), and since ehCache...

Here we are relaxing at Chevy's after a long long day at JavaOne. The guys wearing blue jerseys are from Liferay and the rest are from the Sun team. It was a great time of enjoying good food, brainstorming ideas, and learning from each other.

If you've been following what we're been doing here at Liferay, you'll notice a lot of collaboration with Sun this past year. So now it's time that we make this public. But before I get to that, I want to thank the Liferay community. And if you're reading this, that means you. What am I thankful for? Well. It's simple. We're not alone. Even though Liferay, Inc. has grown as an...

似乎总能听到liferay性能的抱怨， 在一个开源软件中这其实不难理解，就想一台公用的电脑，有人用oracle就在上面装个oracle，有人用DB2就又装了一个DB2…… 这些服务都启动自然就会慢。我们要做的就是停掉一些用不到的功能和方便开发人员debug的一些选项。 启动速度相关参数：在不需要自动创建数据库结构的时候可以停掉此项： #  # Set this to true to automatically create tables and populate with default  # data if the database is empty.  #  schema.run.enabled=false ...

Currently, the WebForm portlet it quite simple. But it was designed to be as simple as possible. Now we have chances to improve it a bit. After the development of the expandos (thanks Ray) the task of storing data with a variable model in a database is much more simple (incredible simple, I must say). You just need to create a table and iterate over the specified fields to add...

Wouldn't it be nice to deploy a portlet to Liferay and have it work as an application in Facebook? Check out our message boards at http://www.liferay.com/web/guest/community/forums Go to the bottom and click "Add to Facebook". We've configured our public message boards to write its output as FBML when consumed by Facebook. Check it out. Every portlet in Liferay is...

This is a new feature I've been wanting to blog about for a while. It was inspired by a request from a customer who wanted to be able to store the different configurations of web forms and be able to later reuse them. For example, at some point there could be a form for "Contact Us", another for "Request for detailed information", another for "Inscription for event X", etc. Not all of...

After seeing all the blog activity on Liferay.com as of late, I was looking for something to really reach out and inspire me to write an entry as well. Well, today a fellow froworker (friend and coworker) emailed me the following link to a MySQL blog: http://www.mysqlperformanceblog.com/2008/04/30/can-having-information-public-hurt-consulting-business/ Within the blog entry, a...

I was introduced to WebDAV the other day, and I thought it would be great to use my first blog post to tell other people about it also.What is WebDAV?Think of it as a way to upload, download, and edit files located in your document library and image gallery from the convenience of your desktop.How to get started.For this tutorial, I'll be using Liferay 5.0.1 on Windows XP. There are...

A few weeks ago our CEO proposed a challenge to me: create a document that shows how to create an Intranet in Liferay in 10 minutes. Here's a demonstration video: Oh, and the document will be available at the Liferay booth at JavaOne.

I love reality checks.. it keeps me grounded.. but these are really hilarious to pass up.  

Hello Hello! I thought I'd use my first blog entry to plug the coming Liferay Meetup =): What: The Liferay Meetup is a FREE event for the Liferay community. We run sessions throughout the day on various topics presented by our own people, integration partners, and clients. The audience is very technical so it’ll be low on salesy marketing content, I promise.  ...

I just wonder in which way liferay does this. use some tools like http://www.review-board.org/?
