Secure JSP Taglibs aims to solve some security issues on the J2EE presentation layer.

Right now the only feature available is to evaluate the nested body content of the tag to test if the user has the specified roles (comma separated); this is equivalent to the isUserInRole() method.

You can test multiple roles at the same time, a feature that already exists in some taglibs like the Logic Taglib in the Struts Framework, but now you can have it using any framework you want.

Using the taglib is very simple. Take a look at the Usage wiki page for examples.
