Hi,

Don't take it personal but you're question is very simple. You may want to read a little bit more about deploying files...

I'll give you a track:

your ACTION tag will have a value (e.g. TARGET1).

<form action="TARGET1" ...>

So, in your WEB.XML, you'll have two very important tags (it is not mandatory, but you should). First one will register your servlet, the second will map your servlet to a URL.

FIRST TAG:

<servlet>
  <servlet-name>MyFirstServlet</servlet-name>
  <servlet-class>package1.package2.myServletJavafileCompiled</servlet-class>
</servlet>

SECOND TAG:

 
<servlet-mapping>
  <servlet-name>MyFirstServlet</servlet-name>
  <url-pattern>/TARGET1</url-pattern>
</servlet-mapping>
 

So, has you can see, the "MyFirstServlet" is a generic name you'll give in your web.xml (the name won't be used anywhere else). The URL could be anything you want. For example, in your web site is:

<a href="http://www.mywebsite.com" target="_blank" rel="nofollow">http://www.mywebsite.com</a>

you'll have to type

<a href="http://www.mywebsite.com/TARGET1" target="_blank" rel="nofollow">http://www.mywebsite.com/TARGET1</a> 

to get your servlet running. So, the ACTION tag should be this link (absolute link or not, depends).

But, as I told you, there's a lot involved in this and it is very difficult to rapidly explain you all.

Hope this helps !

I find the easiest way to confirm ideas is to simply try them
