I did some more testing, and discovered an error in my OP. See inline
below...
I already have a message into the makers of the jni package I'm using
with my standalone app to see if they have any input on this.

Originally, I had the jar's with the classes in question in the
jar/lib/ext folder, because they apparently need to be there for a
standalone app that uses jni to access some of the classes in these same
jars. If I *move* them from the lib/ext folder into the web-inf/lib
folder, then my web app works fine, but my standalone app fails. What I
had initially done when writing my op was to copy the jars, so that they
existed in both lib/ext, and in web-inf/lib, and my web app doesn't like
that, though my standalone app works ok.

in the System classloader it won't see the servlet api at all.

I've read that several times in the past, but it's kind of short on the
information I need. I'll look again...

Why would I get the subject error when I'm deep into my code, and not
near the top when I first use it? I'm getting this in a class that is
buried several layers deep in a utility jar file. The servlet that
calls this class is working fine, I get no compile errors, I am
importing the proper class, and my startup env vars are set to:
-Dcatalina.home=C:\Program Files\Apache Software Foundation\Tomcat 5.5
-Dcatalina.base=c:\TomcatClients\EddSrv
-Djava.endorsed.dirs=C:\Program Files\Apache Software
Foundation\Tomcat 5.5\common\endorsed
Here is the code snippet at issue, and the line where I'm getting the
error. This is in a utility .jar file in web-inf/lib
import javax.servlet.http.HttpServletRequest;
...
public static int updateDb( HttpServletRequest request ) {
HttpSession session;
error line:
session = request.getSession();
This is being called from a class in my .war file:
rslt = TCfgHose.updateDb( request );
It works fine in dev mode in Eclipse, but fails when deployed. What
am I missing? Do I need to put out a jdk after all? Or is there a
problem with passing a HttpServletRequest out of the webapp and into a
utility .jar?
