Re: My first WebApplication

[Schalk Neethling]

Sayeed
First I would suggest creating a web.xml and place that in your WEB-INF/ 
folder. The web.xml allows, among other things, you to set-up 
servlet-mappings which will for one make the current URL you are using a 
lot shorter, secondly because the invoker servlet is now set to off by 
default registering your servlets in the web.xml will make sure that 
Tomcat is aware off them and calls them successfully. Copy the below 
text into a editor and save it as web.xml and place it in your apps 
WEB-INF folder.

<?xml version="1.0" encoding="UTF-8"?>

in your dos window, instead of typing
startup.bat
type
catalina.bat run
and tomcat will run in the same window, and show you the error

DEAR Yoav Shapira
I  have a question for you sir.
I start learning JSP and ohter J2EE tools recently.
I buy a book of "Professional JSP 2nd Edition".
Sir i am facing a problem:
I dowload jakarta_tomcat 4.1.30.exe from the website.
I already do have jdk1.3 at my PC ( iam using win98 OS).
Now after installing jakarta_tomcat to a folder "c\apache\tomcat",
I create two environment variables into my Autoexe.bat file as
       

under :
 

set JAVA_HOME=C:\jdk1.3
set CATALINA_HOME=C:\APACHE\TOMCAT
Now when I Start Tomcat - a DOS base window is opened and remained
       

active
   

for few seconds and then close automatically. Also i try
       

Startup.bat
 

file
   

at
     

MS DOS promt, it shows some lines as follows:
   C:\Apache\Tomcat\bin>startup
   Using CATALINA_BASE:   C:\APACHE\TOMCAT
   Using CATALINA_HOME:   C:\APACHE\TOMCAT
   Using CATALINA_TMPDIR: C:\APACHE\TOMCAT\temp
   Using JAVA_HOME:       C:\jdk1.3
   C:\Apache\Tomcat\bin>
And in the mid also a new DOS base window shows a name 'Java'
       

opened
 

for
   

few
     

seconds and automatically closed.
Sir/Madam, whats the wrong with the tomcat? coz as per book
       

instructions
   

it
     

must shows a Catalina named window and remained active till I did
       

not
 

issue
     

a command Shutdown.
So please guide me what I should do in this connection in detail.
An early reply shall highly bhe appreicated.

Hi,
Make sure the java installations are clean, i.e. there are no extra
       

xml
 

API or parser implementations (or Digester, come to think of it) in
       

your
   

jre/lib/ext directory (off $JAVA_HOME).
