Sorry about that, the SiteMesh integration that we generate with is designed to make it easy for you to customize the headers and footers of the generated UI’s.
SiteMesh is good project, and you can configure it to provide different headers, footers for you pages as well if you have an interest, but if you want to just turn off that behavior, you can add an entry to the excludes section of the decoarators.xml file in your web-inf.
If you need more information about sitemesh and its configuration you can start here.
http://www.sitemesh.org/configuration.html
You can exclude using wildcards and paths so you can easily avoid having sitemesh handle your pages.
If you want to avoid using sitemesh all together and update our generated pages to not use them, etc you can remove the SiteMesh references from your web.xml.
Thanks,
Jack
