My first Servlet accessed from an html page???

**northfield** · 10-02-2002 07:40 AM

I am trying to access a very simple servlet called "ServletOklogin" from an html page.
But unable to do this. My webserver is tomcat.

I think it could be two problems
(1) Path incorrect in the html page
(2) Need an web.xml page

The ServletOklogin.class is located at this path:
D:\tomcat\jakarta-tomcat-3.3.1\webapps\test\WEB-INF\classes
I have the testServlet.html under the test folder, so thus the path is:
D:\tomcat\jakarta-tomcat-3.3.1\webapps\test

Here is the html file:

Code:

<html>
<head>
 <title>testServlet.html</title>
</head>

<body>



Press the submit button:</p>
<form method="get" action="http://localhost:8080/test/servlet/ServletOKlogin">
 
  


  <input type="submit" value="Submit" name="B1"><input type="reset" value="Reset" name="B2"></p>
</form>


</p>

</body>

</html>

What should the path be for the "action" variable in the form??
I have tried other variations like:
"test/WEB-INF/classes/ServletOKlogin"
etc.

but get the error:
HTTP 404 page cannot be found???

I think the problem is I need to produce an web.xml file?????
And this would be placed in the WEB-INF folder located at:
D:\tomcat\jakarta-tomcat-3.3.1\webapps\test\WEB-INF\ ????????

But I do not know what should be in this file?
The book I am using does not give an example of the web.xml file I should produce????

Please help???

The location of the servlet from the html page appears correct as far as the suffix goes (test/servlet/ServletOKlogin).
You could try opening the web browser(IExplorer) and checking for the percise address of the tomcat link. At the Internet Options Connections Lan Settings. Make sure "Use a proxy server is checked with the specified address ie. 192,168.0.1 and specified port ie. 8080". Now use this address instead of the "Localhost".
Better yet, your local system may have a dns..name that you would type in place of the localhost.

Okay it works.
I have tried the same program on another pc.
I think there is something wrong with how the first pc builds new "context areas" for web applications to run.
Any way I have another question.
I have been using jsp and in jsp one could call a "jsp" from an html by entering the line below:

<form method="post" action="ServletOKlogin">

As long as the jsp and html are in the same folder. Why can't one do the same for servlets?

I'm sorry, I do not use jsps and do not know how they handle this.

Whenever you make a request to a servlet, you need to include the entire root address with the /servlet/name attached. This is because the directory the servlet sets in is different by server definition, than the directory the html code sets in.
