This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
For wizard type of screens, or more complex applications, the JSR168/JSR186 spec sometimes doesn't provide enough full featured functionality. As such, the Portal Apache project provides a variety of bridges for certain portals.
Which bridges does the LifeRay Portal support? Does it support Struts and JSF portlets, and for that matter, are there any other common frameworks other than Struts or Java Server Faces that can be wrapped up in a Liferay portlet?
