Keith -RE: Wrapper and Servlet unavailable errors...
Keith,
I apologize for my attitude and that I offended you. I see (now) your previous posts about the problem. What (if anything) changed a day ago when the problem started? Did you check the location of the compiled .class file (AuthenticateServlet.class)? Is it in the WEB-INF\classes directory? So, the error just comes up the first time you access the page after restarting Tomcat? Do you make changes to the servlet code, recompile and then restart Tomcat? Are you using NetBeans all the time to compile the servlet? I wonder if it is a timing problem.

Subject: Re: Wrapper and Servlet unavailable errors...
I find your comments to be unwarrented and quite offensive
and yes I have written three emails about this problem and
posted the error messages that I have gotten. Usually if
ppl need more info they ask for it and I provide. Yes,
the application has worked before and this problem just
started a day ago. I have switch from Tomcat 4.0.4 to
4.1.10 with no better results. I am using the NetBeans
IDE to develop the application. I can run the application
just fine when using the tomcat version under NetBeans.
Trying to use the other version, though, produces these
error messages in succession. Once I get the first error
message about the wrapper not being able to find the
servlet class it doesn't appear again until I restart the
Tomcat4 service. To recap, I have a servlet
(AuthenticateServlet) under the root folder of my app. I
have three jsp pages (login, error, and main). The login
page accesses the AuthenticateServlet to check to see if
the user can log into the database. If so, the user is
redirected to the main page; if not then the error page is
shown. I will attach the source for each document page to
see if you can spot something that I haven't seen yet...

Re: Keith -RE: Wrapper and Servlet unavailable errors...
Posted by KEITH PEMBERTON <ga...@charter.net>.
Don't sweat it... I know that tomcat and the whole
JSP/Servlet world is still a little new to me. Thanks for
the apology and I'm sorry for my attitude as well...
Anyway, I'm am having problems compling the
AuthenticateServlet.java file when I do it manually (javac
AuthenticateServlet.java). I am sure I need to add a
classpath after the javac command, but I don't know what
to add. The errors that it produces all relate to
specific items in the javax.servlet.* packages... I gotta
go for now and will detail more later...
