I have written a small web app (using NetBeans) which has been running
fine for a couple of weeks. Yesterday afternoon, I added a new page to
the program, rebuilt it, created a new .war file and installed it in my
tomcat webapps directory. And tomcat won't start it. The log file
(catalina.out) is listed below.
It complains about a missing class - but what is
com.sun.el.ExpressionFactoryImpl and why would that be missing?? Or is
that actually the missing class? If not, how do I figure out what is not
there?
My program seems to start - it prints the 'App started successfully'
from my init servlet. But when I try to connect to the app from my
browser, I get the null pointer exception - but I don't know how to
figure out where that is coming from either.
Can someone give me a hint as to what might be wrong? Or how to figure
it out? I'm fine with debugging my own code - but I can't get a handle
on where to look.... Have I lost a library somewhere? Netbeans didn't
complain when I built the war file...
thanks very much,
nbc
