| Custom XML descriptors. Use of custom XML descriptors
reduce the complexity of the framework but increase the learning
curve because its a new file to learn. XML descriptors are not
available for code completion in most IDEs. |

| Taglibs. Taglibs are the de facto way of doing web
applications from JSPs, Struts and other frameworks. The main
problem with taglibs is your HTML file will generally no longer be

IDE to support it. |

| Custom rendering engine. One of the more popular
rendering engines aside from the JSP standard is Velocity. However,
that is an additional thing to learn and it also has the same
problem as taglibs where the web development tools are not able to
handle these extra tags. Tapestry, Wicket and Twiff also have their
own custom engine, but are XML based. |

| Abstract base page classes. Using inheritance does make
things easier for framework development and also adds common
functions to the page beans. However, it makes things harder to
change or optimize since developers are locked into the framework
and makes it hard to migrate to future versions. |
