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?
