In the process of migrating the Document Publisher portlet from LRP 4.4.2 to 5.0.1 one of the problems I have found is that in LRP 5.0.1 the URLs for actions and renders in some cases, like URLs...

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...

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...

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...

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...

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...

So, when we adopted jQuery, I think I should have done more to evangelize it within Liferay. For most web developers in the world, it's really taken off in popularity because the concept is tied to...
