I had a experience working with Websphere Portal 6.1 and developed portal applications usign JSR 168,JSR 286 Portlets.
Now i am having a requirement to work on Liferay.
As per programming interface it will be the same ie (JSR's). But want to know what are the major differences at server level ( features,configuration,architecture, out-of-box services) when compared to Websphere Portal ?
