Stripes is an “easy-to-use” web framework to overthrow Struts, as described on [1]. I have not tried it myself, but I quite agree with the disadvantages of using Struts, especially the high learning curve of learning Struts. The tight integration between the components and cryptic errors has also made incremental development difficult. Stripes has made it easy for a new developer do Stripes in less time, but it will be especially easy for a existing Struts developer to switch over because of the large similarities between them.
