myjavaserver (free jsp hosting)
This site was formerly known as mycgiserver. As far as I know it is still free. The orignial description may be outdated though: this site allows you to create dynamic site with HSQL (Hypersonic SQL) databases. I used this to make an example site and found the member forum to be helpful in setting up my site.
