Kevin-
every Servlet has an init(ServletCinfig) method
where you want to make sure you initialise all of the servlet variables
Also perform quick sanity checks by initialising as well as printing the
variable to make sure it is NOT null
and avoid NullPointerExceptions on load
e.g.
YourServlet extends javax.servlet.http.HttpServlet
{
string foo=null;
init(javax.servlet.ServletConfig config)
{
foo="foo";
out.println("foo variable = "+foo);
}

Subject: Error Messages?
I am using Tomcat, and just starting the server, I see these messages that
look like error messages:
SEVERE: Servlet /ibi_html threw load() exception
java.lang.NullPointerException
and
SEVERE: StandardWrapper.Throwable
java.lang.NullPointerException
log4j:ERROR setFile(null,true) call failed.
java.io.FileNotFoundException:
/appls/WebFocusClient/ibi/WebFOCUS71/logs/wfibihtml.log (EDC5129I No such file
or directory
and
SEVERE: StandardWrapper.Throwable
java.lang.NullPointerException
and
log4j:ERROR setFile(null,true) call failed.
java.io.FileNotFoundException:
/appls/WebFocusClient/ibi/WebFOCUS71/logs/wfibihtml.log (EDC5129I No such file
or directory.)
(which sure looks like the previous one)
and
SEVERE: Servlet /approot threw load() exception
java.lang.NullPointerException
and
SEVERE: StandardWrapper.Throwable
java.lang.NullPointerException
and
log4j:ERROR setFile(null,true) call failed.
java.io.FileNotFoundException:
/appls/WebFocusClient/ibi/WebFOCUS71/logs/wfapproot.log (EDC5129I No such file
or directory.)
I say that these LOOK like errors, but the server does come up and nothing
seems amiss. Are these errors that need to be looked at? The problems with
'No Such file or directory' are easy, and I can track those down, but the
others?
