Solution

No, what you are doing is wrong. I guess you want to submit this form to a Servlet(test.java).

First you have to make sure that test.java (btw this is not a proper convention in java for a class name, it should start with an uppercase letter) is actually a servlet by extending the HttpServlet class, and implementing the required methods (doGet() and/or doPost() ...). More Info Here

Then you have to map this Servlet in the web.xml.

<servlet>
    <servlet-name>Test</servlet-name>
    <servlet-class>test.java</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Test</servlet-name>
    <url-pattern>/Test</url-pattern>
</servlet-mapping>

And then submit the form to the url-pattern of the servlet assigned above. In this example your form should look like this:

<form method="POST" action="/Test">

Note: You can use the IDE's servlet wizard to automate this functionality, but Its always better to know also how things work internally.

You can check also https://stackoverflow.com/tags/servlets/info to see how servlets work
