Thanks. So there's absolutely no way within the web browser to print
out the line of code that caused the error? In the example, the line
i would've liked to see in the web browser would have been:
String v1 = session.getAttribute(attr);
Thanks, - Dave

session.getAttribute(String) returns an Object
try:
String v1 = (String) session.getAttribute(attr);

If you need to see the generated code for the JSP take a look at
$tomcat_install_dir$/work/Catalina/
