Help noob! HelloWorld Servlet

Using Windows & Sun Java System Application Server Platform Edition 9.0_01
I just would like to get such result:
http://localhost:8080/HelloWorld?name=MYNAME
Where HelloWorld is my simple servlet displays MYNAME
HelloWorld.java:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Hello extends HttpServlet
     public void doGet(HttpServletRequest req, HttpServletResponse res)
          throws ServletException, IOException
     res.setContentType("text/html");
     PrintWriter out = res.getWriter();
     String name = req.getParameter("name");
     out.println("<HTML>");
     out.println("<HEAD><TITLE>Hello World</TITLE></HEAD>");
     out.println("<BODY>");
     out.println("Hello, " + name);
     out.println("</BODY></HTML>");
I have compiled it and get HelloWorld.class
Then I've copied that calss file to autodeploy folder.
Few minutes later I logged onto the Admin Page and saw that my Web Module appears in Applications -> Web Applications.
I'm trying http://localhost:8080/HelloWorld?name=MYNAME
"HTTP Status 404 - The requested resource () is not available."
I'm trying http://localhost:8080/HelloWorld
and getting just to /HelloWorld/ directory
"Directory Listing For /"
So, what am I doing wrong?
How to access my servlet?

jaikiran, thanks for youe reply
I wish web.xml would be auto created after autodeploy..
But it didn't.
So I've created it myself and put to:
\domains\domain1\applications\j2ee-modules\HelloWorld\WEB-INF
<web-app>
<display-name>heelo</display-name>
<servlet>
<servlet-name>HelloWorld</servlet-name>
<servlet-class>HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
<url-pattern>/HelloWorld</url-pattern>
</servlet-mapping>
</web-app>
And I still getting the contents of direcory.... :(
I've got a feeling that I'm not doing autodeploy correctly...
Maybe there is some tutorial for hand-compiled classes wicha are being autodeployed? :oops:

Just can't run HELLOWORLD servlet on Tomcat!

Hi there, I worked with servlets all summer long and now I'm getting back to build one, and I'm totally confused... My problem's there :
I try to run a simple HelloWorld servlet on Tomcat 4.1, and I get a 404 Error - Not found
Well, here's the structure of my web application, contained in simpleservlet.war :
WEB-APP
-web.xml
-CLASSES
-servlet.class
-LIB
-servlet.jar
Here's now the content of the web.xml file :
<web-app>
     <servlet>
          <servlet-name>serv</servlet-name>
          <servlet-class>servlet</servlet-class>
     </servlet>
     <servlet-mapping>
          <servlet-name>serv</servlet-name>
          <url-pattern>/test</url-pattern>
     </servlet-mapping>
</web-app>
AND FINALLY here's how I invoke my servlet, I TRIED :
http://localhost:1977/servlet/test
AND ALSO
http://localhost:1977/test
AND BANG, I GET "ERROR 404 - NOT FOUND"
A little help would be appreciated A LOT, well it's not supposed to be a hard problem... and by the way, I'm using port :1977, the problem's not there though.
regards, Pierre

Hi,
First try http://localhost:1977 and see if you are getting Tomcat. As you said, this is not a problem. So, you should get the index.html of the Tomcat. Now, click on the one of the example. From the Address Bar, you will know the path of this example. Try putting your page at that location and then run.
This should work.

If you want specific help with a specific problem then you should ask a specific question. "help, JSP and SERVLETS" is not a specific question. And you should also note that if your specific question is about Tomcat specifically or Eclipse specifically then you are in the wrong place to begin with.
So do you want to try again?

HelloWorld servlet help !

Hi,
I compiled the simple HelloWorld.java and put it under /jakata-install-dir/webapps/webapp1/WEB-INF/classes/HelloWorld.class
Then, started the tomcat and this
http://localhost:8080/webapp1/servlet/HelloWorld
gave 404 error ??? file not found ???
Pls help. thanks.
P

I agree tomcat is fussy !!!
Yes, the webapps/examples/WEB-INF/classes works, but
I want to create a new application name say webapp1 to replace the name of "examples" above, then it failed !
I guess there must be some configuration needed to add a new application name after /install-dir/webapps/ ?
Moreover, I can't even log into administration page without the username and password. Cant found them ?!

Running HelloWorld Servlet--Tomcat 4.1

Dear Sir,
With most humble submission I would like to inform you that I have recently downloaded Tomcat 4.1 from http://jakarta.apache.org/ and installed it on Windows 98. I am using jdk1.3
I am an amateur for Java Servlets. I am following the instructions given in the book "Java Servlet Programming" by O'reilly and according to this book I have to store my class files(I tried with HelloWorld.class) in the dir server_root/webapps/root/web-inf/classes dir. but when i called it from microsoft internet explorer 5.0(the browser i am using currently) using the URL http://localhost:8080/servlet/HelloWorld
I get the 404 error.
I also tried to call a static file (.html) by storing it in the dir server_root/webapps/root(according to the book) and i get the proper output but not in case of .class file. Even the example codes provided with the server do not run.
Please help me to fix out my problem.
Thanking you in anticipation,
Yours sincerely
roopesh

Hi:
1)You need set classpath
2) do you open your Tomcat?
Thank

Hi,
Please have a look at the sample applications hosted at http://www.oracle.com/technology/sample_code/tech/java/servlets/index.html.

Help needed on Servlets and JSTL

Hi
I am using tomcat 5.5 and JDK 1.5. What are the softwares I have to download for compiling servlets and creating JSTL ?. Help needed.
Thanks
IndyaRaja

I tried compling servlet, but it is raising error
that coul not find package javax.servletWhat I did not mention... you need to add those JARs in the Classpath explicitly. You will find them in %TOMCAT_HOME%\common\lib. You atleast need to add servlet-api.jar to your Classpath. :)

Help noob please - restaurant menu method please...

I created a basic static website a few years ago using Dreamweaver MX 2004. I am a basic WYSIWIG type of amateur. The site is for a family member's restaurant and has worked fairly well for some time but its getting harder to make updates to the restaurant menus. Items and pricing keep changing and the tables I had put in place get pretty messed up easily since all the item and pricing changes don't totally conform to table characteristics I originally set up.
So, I'm looking for help (remember I'm a noob wysywig type of guy - dont know CSS or anything beyond!) with the restaurant menu techniques.
I wouldnt mind moving the site to a content management type of site if I knew that would could be set up to match requirements and then could be more easliy maintained.
I really appreciate all suggestions and thanks!
An example of the site's menu is HERE.

Let me offer you a few comments because I think you might have gotten a little off track here.
You want to reproduce, as best you can, the look of a menu on paper. On the Internet. And a .PDF will accurately do that but there is a real problem with PDFs. Not all PDF menus will be accurately scanned by the search engines, so if I'm looking for "Mexican food", or "Tex-Mex food" a search may not turn up your website.
From my point of view, your website needs to have content for the purpose of drawing people in to your restaurant to sit down and eat (or to use your catering services, assuming you do that as well).
So let's consider what's on your website from that standpoint.
Your current menu is laid out in tables. I have consistently found that search engines will tend to rank a website lower when it is laid out in tables. I am guessing that the amount of in-line definition overwhelms the search engines when they are looking for content. Take, for example this line:
<td height="20"><font face="Comic Sans MS" size="2">Jalapeno Poppers</font></td>
(this is line 175 in your source code).
If search engines are looking for the term "Jalapeño Poppers," they have to wade through a font face definition, height of your cell and size of the font before they actually get to the term. You mentioned straight out that you don't know CSS. But were you to define a header level in CSS, as well as your columns, you would get the following for this same item:
<h3>Jalapeño Poppers</h3>
Need it in Comic Sans? Define the <h3> tag to be Comic Sans. Need it centered? Define that as well. Need it a certain size? No problem. Now, the browser reads in your CSS, stores that in memory and then renders all pages based on that CSS out.
I have just done a few restaurants and have more in process. Restaurant websites in my area are universally bad. A website that is constructed using modern techniques of CSS and HTML will certainly stand out and garner more hits, based on people stumbling on the website from search.
Unless you are constantly changing prices, you don't need to use a database. All you really need is good code and the time necessary to do occasional price updates. Dreamweaver's WYSIWYG (almost) Design view makes simple price changes and editing easy.
And if you have bit off more than you can chew, consider having a professional designer do the restaurant website and simply maintain what the designer did.
A few additional notes:
You have your East Moline breakfast menu set as one large .jpg That is absolutely not searchable, so if someone is looking for a delicious breakfast burrito, they're not going to find you.
Your page titles don't change and your physical address may not be the right kind of title. Also there is no unified navigation on your website. People who look at your menu might want to look at your catering options as well.
I like the fact that you have lots of content there. Were I doing the website, I'd have a good start to go on.

SOme more help on JSP-Servlets-Beans plz...!!

Thanx a lot for your help !
But I could not understand some things ...
Suppose, I create 5 bean instances in my servlet, & "set" them with data from 5 tuples.
Now, I need to pass these 5 bean objects to a JSP .
HOW exactly can I pass them via a List object thru request attribute ?
And, after doing that, HOW will I be able to access the individual Bean objects in the JSP ?
Plz., see if you can send me some Code Snippets that illustrate the same.
Once again, Thanks a lot for bearing with me !!
Awaiting your response...
Truly yours,
Raghu

Servlet:
request.setAttribute ("someUniqueName", yourBeanList);
JSP:
Either <jsp:useBean> or insert a scriplet like <% List beanList = (List) request.getAttribute("someUniqueName"); %>

Need urgent help on Applet-Servlet communication

Hi,
I have a applet having two button A and B. A passes querystring "Select name from test where letter = A" when button A is pressed while B passes querystring "Select name from test where letter = B" when button B is pressed. The applet passes the string to a servlet which in turn queries a database to get the output name back to the applet. Both compiles fine but while running I am getting the following error:

Since you are just using Strings, it's easier to use an ObjectOutput/InputStream. See http://forum.java.sun.com/thread.jsp?forum=33&thread=205887 for a detailed example.
