Servlet on tomcat 4.1.18

I am facing a problem of running servlets on Tomcat 4.1.18. The problem seems to be in the configuration. In the webapps folder, I created a folder greeting. In that, the WEB-Inf\classes folder has GreetingServlet.class.
webapp\greeting has index.html that has to FORM ACTION set to /greeting/servlet/GreetingServlet.
On clicking the submit button the message I get is that the resource /greeting/servlet/GreetingServlet is not found.
Can anybody help in configuring the server so that the above mentioned servlet gets recognized?
Thanks.

My application is located at %TOMCAT_HOME%\webapps.
%TOMCAT_HOME%\webapps\greeting\WEB-INF\web.xml has the following:
<web-app>
<servlet>
<servlet-name>greeting</servlet-name>
<servlet-class>GreetingServlet</servlet-class>
</servlet>
</web-app>
%TOMCAT_HOME%\webapps\greeting\index.html has the following:
<FORM ACTION="/greeting/servlet/GreetingServlet" METHOD="POST">
<P> Your name <INPUT TYPE="text" SIZE="40" NAME="name"></P>
</FORM>
Yet the problem persists.
Have I missed some point?
Help/assistance will be appreciated.
Thanks.

Servlets in Tomcat

I am trying to run servlets using Tomcat. I have them working and displaying but as soon as I make a change to a servelt and re-compile and refresh the browser the change do not take effect. I have to shutdown and restart tocat. Surely this can't be right. can anyone help with correcting this problem?

Lesta,
For convenience there's a Tomcat admin console. The admin console runs through a web browser and allows you to restart an application, restart a context ect. I think you can also install or reinstall entire ears through it now.
There's some setup to do before you can use the admin console. I seem to remember there being an XML user/password file somewhere...
In a production environment you don't want to shutdown and restart the daemon like you are doing. It will just annoy the heck out of your users.
Hope this helps.

I have Tomcat version 4.0 installed on my machine. If you look at the directory where you have Tomcat installed, you should find the directory structure:
tomcat-folder/webapps/root/web-inf/classes
Try placing your class files in the classes folder.

How to Run servlet in Tomcat 5.5.9

hi
How to run servlet in tomcat 5.5.9?how to set context path in server.xml of conf folder in tomcat since there is no context tag in server.xml.
Jiten

Hi ! I have a similar problem, well, it's along the same line ...
I'm using NetBeans 4.1, and i've coded a servlet. Using NetBeans to launch my servlet (with the bundled Tomcat 5.5.7) works fine, however i need to deploy my application unto a Tomcat 5.5.9 server.
Thus, i copied the WAR file generated by NetBeans into the Tomcat 5.5.9 webapps directory, and Tomcat expands it.
Problem is when i run my JSP pages with the form tags, they do not work on the Tomcat 5.5.9 environment. Anyone knows why?
(These work on the NetBeans Tomcat bundle 5.5.7)
My form action :
<form name="index" method="get" action="PageServlet">
My web.xml :
<servlet>
<servlet-name>PageServlet</servlet-name>
<servlet-class>application.PageServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>PageServlet</servlet-name>
<url-pattern>/PageServlet</url-pattern>
</servlet-mapping>
I'm really stumbed on why it doesn't work in Tomcat 5.5.9, any help is greatly appreciated, thanks in advance ^_^

How to run Servlet in Tomcat 5.5.7 Server

Hi,
How to run Servlet in Tomcat 5.5.7 Server. I mean where I should copy my *.class file.
Thanks in Advance.
bbye.

In order to complile the servlet you need to tell java where to find the servlet libary (as stated above by setting the class path). or (much easier IMO)
copy the servlet-api.jar to
JavaInstallDirectory\jre\lib\ext

To start, make sure you have specified the servlet and mapping in your application's WEB-INF/web.xml file.

<servlet>
    <servlet-name>yourServletName</servlet-name>
    <servlet-class>path.to.Servlet</servlet-class>
</sevlet>
<servlet-mapping>
    <servlet-name>yourServletName</servlet-name>
    <url-pattern>/servlet/yourServletName</url-pattern>
</servlet-mapping>

Run servlet in tomcat 4.1

Hi ,
could someone please help me.
Iam trying to run servlet in tomcat4.1 but in vain.
please help

hi
If you want run a servlet in tomcat4.1,First write one html file,and servlet file.
finally you need to write web.xml.this file will be placed in web-inf folder.
You need to write this tags to run a servlet in tomcat 4.1
<servlet>
<servlet-name> name of the servlet</servlet-name>
<servlet-class>class name of the servlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>name of the servlet</servlet-name>
<url-pattern>/the ref name which u want call servlet</url-pattern>
<servlet-mapping>
Here the servlet name sholud be same .
The url pattern name must match with the action attribute value in html.
now you place your html file in root folder.
place your servlet class file in classes folder.
start ur browser type this http://localhost:8080/htmlfilename.

Newbie question about loading servlets on tomcat

I have what is probably a very basic question about loading simple servlets on to tomcat to test its installation. I have followed instructions from numerous tutorials to the letter but still I can't get it to work.
I have installed tomcat on win2k in c:\tomcat. I set up the jdk, environment vars (JAVA_HOME, CATALINA_HOME, TOMCAT_HOME) which all point at the correct dirs. I can compile a servlet without errors. I can also place a test jsp and html file into the root directory and they both work fine.
However, now I am trying a test servlet and no matter what I do it gives me a 404. I have a servlet class file called "HelloServlet.class" which I placed into the %install_dir%\webapps\ROOT\WEB-INF\classes directory. I try to reference it using this url:
http://localhost/servlet/HelloServlet
Tomcat is configured to use port 80 and has been restarted after adding the servlet class file. Does anyone have a clue why this is not working for me?
Many thanks
Marc

You have to add in the web.xml file that it is in the WEB-INF dir, the information about your servlet. An example:
<web-app>
<servlet>
<servlet-name>HelloServlet</servlet-name>
<servlet-class>HelloServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloServlet</servlet-name>
<url-pattern>/HelloServlet</url-pattern>
</servlet-mapping>
</web-app>

There seems not to be any '.html' in your url-pattern

http://yourhost/Logininstead.

inside this create directories as follows :

        |
        |-----WEB-INF(File Folder)

                   |-----classes ( .class files. )[all of your java code should be placed here.](servlets / beans/ pojo )this is the general Directory structure of a web application. now you've to place the compiled .class file of your servlet in the "TestApp\WEB-INF\classes" directory. make sure that you've configured the servlet in Deploment Desctiptor, i.e, web.xml.
now start the server and type the url like : "http://localhost:8080/TestApp/TestServlet"
the port no. 8080 is the default port no. of tomcat. you have to give your port no. if u've modified it. and TestServlet is the <url-pattern> of your servlet.
go through some tutorials .. then you can easily know that
