I am trying to precompile my JSPs using Tomcat 4.1.24's jspc utility and am getting a
ClassNotFoundException for class org.apache.struts.util.PropertyMessageResource (stack
trace below). I googled and found no hits except for an old struts-users thread where
Craig told someone that Tomcat 3.2.3 had classloader problems that were resolved by
3.3 - and I'm on 4.1.24.
Any ideas are appreciated - I have absolutely no clue.
