Hi, If I place my html file under WebContent, I am able to load my servlet. If I move html file to some folder under WebContent directory, I am getting HTTP Status 404 error. Please let me know

If you file is under WebContent you can access by "/file.jsp"
If you move your file, you will have to put the path "folder/file.jsp" or "/folder/file.jsp" i can not tell you for sure now.

Could you post your code here? and your tree folders?

As suggested by Victor , issue could be with url pattern mapping , if you could post your web.xml , we can help probably help better.

This will work because we are calling Servlet directly. Requirement is, I have to call the Servlet from html file that is located in a directory.

This is covered in the FAQs. You should be using a server-relative URL for the action that starts with the context path.

For example:

P.S. What's with the ".do"? Just because Struts uses that as a pattern to invoke its dispatcher doesn't mean it's necessary for all servlets.

I believe it's one of the JSP FAQs.

This is how to declare a form action to a Servlet. (The same applies to referencing images, scripts and stylesheets).

Looks like your web is is misconfigured such that the EL is not enabled.

Be sure that your web.xml is correctly declared as outlined in the JSP FAQ. (For example, if you are using the Servlets 2.3 DTD in your web.xml, it's wrong.)

I don't have DTD. I see xsd in my web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

Then the EL should be enabled in your JSPs.

What happens when you hit a JSP that contains just the following:?

OK, the EL is correctly enabled. Be sure you are not disabling it on the page in question.

Then take a look at the HTML for the <form> element after is has been sent to the browser. Does it look correct?

1) There are directives that will disable the EL. Be sure you are not using them.

2) Look at the HTML in the browser. Usually something like "View source" on the menus.

Hi Bear,

I do not have any directives as given in the source code above. View source looks good to me.

First of all, rename your "TestMe.html" to "TestMe.jsp".
Then, modify your form declaration to: .
After that, test the JSP in the browser and verify that in the outputed HTML (view source), the action in the form is "/ctWeb/TestServlet.do".

I see the following, when I say, view--> source

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>

</head>
<body>
<form action="/ctWeb/TestServlet.do">
<input type="submit" value="Send"></form>
</body>
</html>

It is working fine now..Thanks Nick and Bear. Renaming from "TestMe.html" to "TestMe.jsp" fixed the issue.
