I keep getting error messages like this one; "The requested resource (/myServletWAR/servlet/HelloServlet) is not available." I am running Tomcat add-on for Plesk 7.0.3 on Redhat 9.0. What is going on here?

As I look up catalina.out, I see this error message; "cannot use jvm jre-1.4 access bug workaround die." Does this have anything to do with this problem? Is this why servlet(Tomcat) is not working?
