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...

Nate Cavanaugh | 2008-4-24 下午10:53

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...

Updated: Wed May 28 10:53:09 EDT 2008. See the follow-up article here. In Javascript, "expando" means "to attach additional properties to an object". That's a little bit of hint as to what Expandos...
