Pros and Cons – When to use a Portal and Portlets instead of just Java Web-Frameworks

Posted in Application Server, Java / JEE, Web Framework on October 7th, 2011 by Kai Wähner

I had to answer the following question: Shall we use a Portal and if yes, should it be Liferay Portal or Oracle Portal? Or shall we use just one or more Java web frameworks? This article shows my result. I had to look especially at Liferay and Oracle products, nevertheless the result can be used for other products, too. The short answer: A Portal makes sense only in a few use cases, in the majority of cases you should not use one. In my case, we will not use one.

Categorization of Web-Frameworks in the Java Environment

The following article shows a categorization of Java / JVM web-frameworks, considering different types of web applications. The intention is to give an overview, not to start a flame war.


An uncountable number of web-frameworks exists in the Java environment. If you visit IT conferences or google for comparisons, almost always you find a discussion about the advantages and disadvantages. Often, a flame war is the consequence, each guy likes or dislikes a specific framework. Thus, a neutral comparison, which helps to choose the one which fits best for your requirements, is rare.
