I have a question from the Head First Servlets and JSP book. I solved the problem that I had as I was creating this post, but I decided to submit it anyway because other people might be having the same problem.
I successfully installed Apache Tomcat version 5.0.28 (along with J2EE and Java standard edition) on a computer with Norton AntiVirus and the Windows XP operating system (with all of the available bug fixes and security updates). When http://localhost:8080/ is entered into the address text field of the Internet Explorer 6 web browser, the default "you've setup Tomcat successfully" page is displayed. (Apparently, I also correctly set the environment and class path variables for the two versions of Java and Tomcat.)
So then I created the form.html file and put it into the directory: C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\Beer-v1. Then I would enter http://localhost:8080/Beer-v1/form.html in IE6, but the form would not display, (only the default error page). So I rebooted my computer several times and cleared the cookies, temporary files, and history information from IE6. I still could not get the form.html page to display, so I put a copy of form.html in the ...webapps\servlets-examples folder. Typing http://localhost:8080/servlets-examples/form.html in IE6 got the form.html page to display.
However, I tried one more time to get the form.html to display from the Beer-V1 directory and it finally worked. (I also passed the previous version of the SCWCD exam with a good score, so I'm not a total beginner to servlets and JSP).
Does any one know why the example in the book would not work and then finally work after several attempts? Also, the examples in the book appear to be for a Unix or an Apple computer, and the instructions for getting Tomcat had a minor error, but I was able to easily solve those issues. I thought the answer to the problem might require setting permissions for the folders and/or users on my computer.
Hi Paul Heckman, This is not regarding the problem you posted.I need a help for my problem.I have been trying you setup Tomcat 5.0.28.But i couldn't make it.On startup it is throwing hell lot of exception. Can you share with me what kind of problems you faced and the remedies for the problems.

I'm not an expert in Tomcat nor J2EE, but I was able to intall and use Tomcat 5.0 and J2EE and work the examples from chapter 1 of the Head First Servlets & JSP (I'm now half way through the book). Probably the most common error is that Tomcat may be automatically running on a computer. (I'm assuming that you use Windows). So every time a computer is turned on or rebooted, Tomcat is running. And if you attempt to restart it by running the Startup.bat file, you will get numerous errors listed from the DOS window. To find out if Tomcat is running, right click the Task Bar, (the menu bar with the Start button that is usually on the bottom of the screen) and then right or left click the menu option named 'Task Manager'. Look for tomcat5.exe to see if it is in the list under the Processes tab in the column titled 'Image Name'. There may be countless other errors why Tomcat will not run. 1) Class paths may not correctly indicate where where Tomcat, J2EE and J2SE are intalled. 2) Missing files from the Windows Operating system caused by malicious viruses that are designed to delete files requied to run Tomcat and or Java on a Windows platform (anti-Microsoft geeks believe that no one should be able to use Java or Tomcat with Windows.) 3) Programs such as Norton Utilies (I'm not sure of this reason, but I think it is a security issue). 4) You may be starting the Startup.bat or Startup.sh file when the other is required (one is for Windows, the other for Unix).
To make a long story short I would have to take a look at the errors you are getting, the environment variables, and the directories where you intalled Tomcat, J2EE and J2SE. Let me know if you have any more questions or if any of my gabbering makes sense.
P.S. I live in Sunnyvale, CA and you are close by I could take a quick look at your computer.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
