I’ve been trying to run the example from chapter 19 (Jess in Action), but I keep getting this error:   The version of Tomcat that I’m using is Apache Tomcat 5.0.19   org.apache.jasper.JasperException: Unable to compile class for JSP   An error occurred at line: 3 in the jsp file: /catalog.jsp   Generated servlet error:     [javac] Compiling 1 source file   C:\Program Files\Apache Software Foundation\Tomcat 5.0\work\Catalina\localhost\Order\org\apache\jsp\catalog_jsp.java:50: java.util.Iterator is abstract; cannot be instantiated           queryResult = new java.util.Iterator();                         ^ 1 error   I downloaded the code from the book’s website, and follow the instructions given in the book.   Thanks,   Francisco   ---------------------------------------------------------------------- Department of Computer and Information Sciences University of Alabama at Birmingham
