Relative path called with HTTPServlet

I am currently developing a servlet which returns a lot of data to a given ID. It is called under the URL

localhost:8080/RTC_W/api?id=123

and has no special path given in the source code. My web.xml maps it as followed:

<servlet-mapping> <servlet-name>APICaller</servlet-name> <url-pattern>/api</url-pattern> </servlet-mapping>

It is called by a welcome file, which looks like this (relevant part only) and offers a little box to type in the ID:

<body>
RTC W Front End

<form action="/api" method="get"> 
  Work Item ID:<br>
  <input type="text" name="id" value=""><br>

  <input type="submit" value="Submit">
</form> 
</body>

as you can see, form action should call path /api where the servlet is located. The URL called is wrong though, it always calls

localhost:8080/api?id=123

So the /RTC_W/ is missing. If I add it to <form action="RTC_W/api" method="get">, this URL gets called:

localhost:8080/RTC_W/RTC_W/api?id=123

So the path is called twice. What am I doing wrong?

<form action="api" method="get">

This is what you should use.

When a URL starts with / it is always an absolute URL, i.e. appended right after the <hostname>:<port>

If a url does not start with / it will get appended to the current URL.
