This zip file contains an example webapp that causes a stack trace when I run
it with tomcat6
I'm relatively new to programming with JSP, but I'm an experienced programmer.
I think it is more likely that my configuration on my PC is wrong than this is
a bug, but I'm stuck because I can not read the standard tag libraries
properly. I have read and reread as much documentation as I can and everything
looks like it should run ok.
I have been working with an experienced JSP programmer at the Javaranch website
and after looking at my problem with me over the past 2 weeks, he is also
stumped.
A bit of history. The webapp that I'm trying to run is an example from "Java
Server Pages, 3rd edition" It used to run ok on the laptop I had last year.
I was taken away from JSP programming for roughly a year. My old laptop died
and when I recently installed the webapp on my new laptop, I ran into this
problem.The old laptop had tomcat6 running and had been downloaded and
installed by me. The new laptop has tomcat6 downloaded and installed by the
adept package manager.
I have attached a zip file which contains a minimal webapp that reproduces my
problem. This zip file should be placed in /var/lib/tomcat6/webapps and then
unzipped. It creates an app "bad". Note that this has some older jar files
in the WEB-INF/lib directory, but as far as I know tomcat6 should be backward
compatible with these jar file.
>From the browser I enter an address: http://bad/ch5/easy.jsp
and I get the stack trace. If I edit the easy.jsp file an comment out the 2nd
line which is a tablib file, it eliminates the stack trace.
The stace trace is:
