ICEfaces涉嫌抄襲PrimeFaces

ICEfaces 3發(fā)布后，本來(lái)我是很激動(dòng)的，以為這是一個(gè)偉大的版本。但是，PrimeFaces的同行們發(fā)現(xiàn)了ICEfaces抄襲了PrimeFaces的部分代碼。ICEfaces的行為真令人失望！

由于PrimeFaces和ICEfaces都是開(kāi)源產(chǎn)品，因此抄襲在法律上沒(méi)有問(wèn)題。但是在道德上，則無(wú)法過(guò)關(guān)。抄襲的代碼對(duì)比如下：

一、PrimeFaces PanelRenderer

ICEsoft公司在開(kāi)發(fā)ACE組件集時(shí)，把PrimeFaces的代碼直接復(fù)制過(guò)來(lái)，然后修改包名和類名，其它的代碼都是照搬。這種行為真丟臉。
結(jié)論：ICEfaces的行為讓人及其失望，用PrimeFaces的開(kāi)發(fā)者的一句原話作為本文的總結(jié)：“您可以復(fù)制我們的代碼，但您永遠(yuǎn)也拿不走我們的激情！”。
