Hmmm... and I take it you are sure the version being used when the stack
trace is produced is the same version you are looking at. In that case
my next thought is to check for a classloader issue. Do
StrutsPageLifecycleFactory and DefaultStrutsPageLifecycleFactory only
exist once in tomcat (if in common/[classes|lib], it can't be in
WEB-INF/[classes|lib] and vice-versa)? Lastly I'm wondering if there's
a problem if DefaultStrusPageLifecycleFactory is in a different
classloader than StrutsPageLifecycleFactory?
Overall I'm guessing this is some sort of classloader issue.

Hi again,
thanks for your interest, David.
Well, found that line 68 in StrutsPageLifecycleFactory.java is empty !!
The method menetioned is the following, and line 68 is the one above
the return statement:
private static StrutsPageLifecycleFactory getDefaultInstance()
{
if (defaultInstance == null)
{
defaultInstance = new DefaultStrutsPageLifecycleFactory();
}
return defaultInstance;
}
I don't know whether sometime it contained something, but no doubt I
haven't edited it !
BTW, forgot to mention that some other Web applications I've got work
fine.
Thanks again for any suggestion.

... so what class is referenced at line 68 of
StrutsPageLifecycleFactory.java? It's weird that it didn't include
the class name it couldn't find in the stack trace.

Hi all,
since a couple of days ago I've been experiencing problems with a
Web application of mine that worked fine until then: when I deployed
the application (built with Java and JSP) under my Tomcat 5.0.28 I
got the following error stack (sorry for the length):
HTTP Status 500
The server found an internal error tha prevented it from fulfilling

I would say that I am 99% sure that it is not due to an error in my
code (the same code worked three days ago), and I haven't changed
anything else.
Could somebody cast some light on this error, please?
I am unable to make head or tail of it. And I did not find any
useful information on the Web.
Many thanks in advance !!
