Subject RE: switching to 6.0 - considerable things?
Date Tue, 03 Apr 2007 11:43:33 GMT
If it helps at all, I just moved my company's apps from 5.5 to 6.0.  The
only stumbling block was they rely on the invoker servlet.  I changed the
build process to find all classes which implement HttpServlet and add an
explicit mapping to /servlet/com.mycompany.package.Servlet in web.xml.

The only other gotcha is that the class loader hierarchy is different
("simplified") in 6.0.

Everything else just worked at that point (Apache+mod_jk, connection pools,
etc.)
