If things Go Wrong and your Tomcat Server Goes Off or Gives Error or Some Problem then checkout
1) Windows 98, Windows 95 users :: Open your C:\autoexec.bat and Edit it using notepad u must be able to see something like this SET JAVA_HOME=d:\jdk1.3.1 SET PATH=c:\windows;c:\windows\command;d:\jdk1.2.1\bin;D:\ORACLE95\BIN;c:\ SET TOMCAT_HOME=d:\tomcat 2) Windows XP, Windows NT, 2000 and Advanced Server users :: Right Click MyComputer Click on Properties Click on Advanced Click on Environmental Variables u must be able to see something like this JAVA_HOME=d:\jdk1.3.1 PATH=%systemroot%\system32;%systemroot%;%systemroot%\system32\wbem;d:\jdk1.3.1\bin SET TOMCAT_HOME=d:\tomcat 3) If you get out of environment error message Win98 users Right Click DOS Click on Properties Click on Memory Select Initial Environment = 2816 ALWAYS RESTART YOUR COMPUTER IF YOU CHANGE ANY SETTINGS |

| Step 4 :: If things go Right and TOMCAT Started ! | |||||||||||
|
open your internet Explorer and type in http://localhost:8080/index.html and u can play with servlet and JSP examples
|
|||||||||||
| Step 5 :: Package not found Error When you Compile ! | |||||||||||
Dont ask me why ? , But it is nessasary that all your java files must be in this Directory
D:\tomcat\webapps\examples\WEB-INF\classes so u are in this directory and
wanna compile a java file say index.java u can give the command like this
D:\tomcat\webapps\examples\WEB-INF\classes>javac index.java , If its your good
day u wont get any errors , else u will get a screen like this
 SOLUTION : all u need to do is setup ur classpath properly just copy & paste (Type in MSDOS) this line in bold at D:\tomcat\webapps\examples\WEB-INF\classes> SET CLASSPATH=d:\tomcat\lib\ant.jar;d:\tomcat\lib\jaxp.jar;d:\tomcat\lib\servlet.jar; d:\tomcat\lib\parser.jar;d:\tomcat\lib\webserver.jar;d:\tomcat\lib\jasper.jar Be carefull about any unwanted spaces ! and Re-Compile the java file D:\tomcat\webapps\examples\WEB-INF\classes>javac index.java If compiling goes right then u will not get that class not found Errors |
|||||||||||
| Step 6 :: Setting up ODBC | |||||||||||
|
If you wish to go further and your Application required you to set ODBC
Click on Start -> Settings -> Control Panel -> Administrative tools -> Data Sources (ODBC) -> User DSN -> Add -> Microsoft Access Driver *.mdb -> Finish 
In Data Source name type in Example "shop" -> Select -> Driver D: -> Select the folder
where you have your mdb file in my case d:\tomcat\database\shop.mdb -> Click OK -> OK again -> OK once more
 |
|||||||||||
| Step 7 :: Accessing Your Java Files | |||||||||||
|
Now that u have compiled ur index.java file to access the same file open ur internet Explorer
type in http://localhost:8080/examples/servlet/index (REMEMBER NO .java or .class at the END of this Line )
by the way index.java is in my Jewels.zip file |

| NEW TOMCAT HIGHER VERSIONS - 4.1.27 | |||||||||||

I guess the guys have learnt from their mistakes , so this version is more stable after 3.2.1 and works better 1) Download jakarta-tomcat-4.1.27.exe from the jakarta.apache.org 2) Click on the EXE and install itin C:\Tomcat directory, i prefer this 3) check installation at http://localhost:8080 in your browser u must see the yellow cat 4) Save this file Below as HelloWorld.java in C:\Tomcat\webapps\examples\WEB-INF\classes Directory 5) go to above directory compile the code C:\Tomcat\webapps\examples\WEB-INF\classes\>javac HelloWorld.java if this go fine u wont get any error during compiling 6) In your browser type in http://localhost:8080/examples/servlet/HelloWorld then u will see My Hello World
import java.io.*;
import java.text.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloWorld extends HttpServlet
{
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>My Title</title>");
out.println("</head>");
out.println("<body bgcolor='white'>");
out.println("<h1>My Hello World</h1>");
out.println("</body>");
out.println("</html>");
}
